&lt;td&gt;Bentley Technical Support Group&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Question:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="padding-left:30px;"&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;When this option is selected, you will obtain the values of allowable stresses according to ASME II Part D, even if you change the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;When this option is selected, you will obtain the minimum values between the allowable stresses according to ASME II Part D and the calculated using the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1680.Untitled.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1680.Untitled.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;When this option is selected, you will obtain the calculated allowable stresses using the safety factors.&amp;nbsp;&lt;/span&gt;&lt;span&gt;The allowable stresses issued from ASME II Pert D are ignored.&lt;/span&gt;&lt;/p&gt;

&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Question:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="padding-left:30px;"&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;When this option is selected, you will obtain the values of allowable stresses according to ASME II Part D, even if you change the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;/table&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Question:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="padding-left:30px;"&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;&lt;span style="color:#993300;"&gt;&lt;strong&gt;Question:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="padding-left:30px;"&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;&lt;span&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin-left:60px;"&gt;&lt;span&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span&gt;&lt;img alt=" " border="0" src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" border="0" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" border="0" alt=" " /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;When this option is selected, you will obtain the values of allowable stresses according to ASME II Part D, even if you change the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png" border="0" alt=" " /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;h1&gt;&lt;span style="color:#993300;"&gt;&lt;strong&gt;Problem:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;&lt;span style="color:#993300;"&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;

&lt;td style="text-align:right;"&gt;&lt;strong&gt; &lt;/strong&gt;&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;Problem:&lt;/h1&gt;
&lt;p&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;Answer:&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;strong&gt;&lt;span style="color:#ff0000;"&gt;Note:&lt;/span&gt;&lt;/strong&gt; If &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;Code values&lt;/span&gt;&lt;/strong&gt; radio button was selected and pressed the &lt;strong&gt;&lt;span style="color:#ff6600;"&gt;View&lt;/span&gt;&lt;/strong&gt; button, data is only available for viewing, i.e. &amp;nbsp;No changes can be made.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" border="0" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;If your Design Pressure Code is ASME:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0167.4.png" border="0" alt=" " /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;When this option is selected, you will obtain the values of allowable stresses according to ASME II Part D, even if you change the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/4353.5.png" border="0" alt=" " /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;When this option is selected, you will obtain the minimum values between the allowable stresses according to ASME II Part D and the calculated using the safety factors.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1680.Untitled.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1680.Untitled.png" border="0" alt=" " /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;When this option is selected, you will obtain the calculated allowable stresses using the safety factors.&amp;nbsp;&lt;/span&gt;&lt;span style="color:#008000;"&gt;The allowable stresses issued from ASME II Pert D are ignored.&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;

&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" border="0" /&gt;&lt;/a&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;h1&gt;Problem:&lt;/h1&gt;
&lt;p&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;Answer:&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;

&lt;td style="text-align:right;"&gt;&lt;strong&gt; &lt;/strong&gt;&lt;/td&gt;
&lt;td style="text-align:right;"&gt;&lt;strong&gt; &lt;/strong&gt;&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;h1&gt;Problem:&lt;/h1&gt;
&lt;p&gt;Input user defined material factor of safety for changing design allowable stress as per various codes in AutoPIPE Vessel&lt;/p&gt;
&lt;h1&gt;Answer:&lt;/h1&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt; Input user defined material factor of safety for changing design allowable stress as per various codes.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;If there is no provision to select material directly based on a particular code/standard (eg. ASME) offered by AutoPIPE Vessel, the user has to input a user-defined safety factor. Shown below is an example of a storage tank design made with SS304L plate material at 50 degree C design temperature with API 650 code based safety factor:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The material allowable stress for SS304L plate at 50 deg C should be 114 MPa as per ASME as shown below:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8182.1.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now if the user wants to change this design allowable stress by using the safety factors of API 650 following is the method:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Under Tank Properties&amp;gt;Design Parameters &amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; instead of the default &amp;ldquo;Code Values&amp;rdquo; and click &amp;ldquo;Edit&amp;rdquo;.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;&amp;nbsp;Once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, select Stainless Steel and change the factors C1 and C2 to 0.3 and 0.9 respectively following API 650 Table S-2a. Then click OK.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/0184.2.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Now the user can check the Material tab for the shell component of the tank, the Allowable Stress should now show according to API-650 maximum allowable (which is 144 MPa in this case).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/690x0/__key/communityserver-wikis-components-files/00-00-00-00-41/1781.3.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The method of changing the safety factor using the user-defined option for Pressure Vessel and Heat Exchanger is similar. Under The Vessel (or Heat Exchanger) Properties window&amp;gt;Design Conditions tab&amp;gt; Safety Factor, select &amp;ldquo;User Defined&amp;rdquo; and click on Edit.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8836.4.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/8814.4.jpg"&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;Then once the &amp;ldquo;Untabulated Allowable Stresses Computation&amp;rdquo; dialog box appears, change the factors C1, C2 etc. accordingly and click OK.&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg"&gt;&lt;img alt=" " src="/resized-image.ashx/__size/490x0/__key/communityserver-wikis-components-files/00-00-00-00-41/2146.5.jpg" border="0" /&gt;&lt;/a&gt;&lt;a href="/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-41/5.jpg"&gt;&lt;/a&gt;&lt;/p&gt;
