&lt;h1&gt;&lt;span style="color:#993300;text-decoration:underline;"&gt;&lt;strong&gt;Problem:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:60px;"&gt;How to optimize Body flange design in AutoPIPE Vessel?&lt;/p&gt;
&lt;h1&gt;&lt;span style="color:#993300;text-decoration:underline;"&gt;&lt;strong&gt;Solution:&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p style="margin-left:60px;"&gt;Body flanges can be a very expensive component of a pressure vessel particularly if the material of construction is expensive eg. nickel alloys or stainless steel. Hence performing an optimum flange design is critical for a cost effective solution.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;AutoPIPE Vessel flange design module offers several optimization methods eg. EN 13445 Annex. G, with compression rings, loose and bolt tensioning options.&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;There are 4 options available for optimization based on hub stress and gasket circle reaction optimizations and also another design method based on bolt load namely design, full or controlled bolt load.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Shown above are the results from a case study on the design of a body flange using the hub stress and gasket circle reaction based on the 4 optimization methods available in AutoPIPE Vessel.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;In summary one can easily observe how much difference in cost each of the methods can result to.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Options 2 and 4 which are the higher cost options, lead to a much more safe and conservative design with significantly reduced hub stress but with 40%-55% cost increase.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Options 1 and 3 result in more compact flanges with smaller hub length and flange diameter but at the cost of higher hub stress. &lt;br /&gt;Hence the optimization method provides a valuable iterative approach to arrive at the most optimum design based on the cost vs. performance criteria.&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/22464.1.png"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/22464.1.png" /&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;Body flanges can be a very expensive component of a pressure vessel particularly if the material of construction is expensive eg. nickel alloys or stainless steel. Hence performing an optimum flange design is critical for a cost effective solution.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;AutoPIPE Vessel flange design module offers several optimization methods eg. EN 13445 Annex. G, with compression rings, loose and bolt tensioning options.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:120px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png" alt=" " /&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;There are 4 options available for optimization based on hub stress and gasket circle reaction optimizations and also another design method based on bolt load namely design, full or controlled bolt load.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;Shown above are the results from a case study on the design of a body flange using the hub stress and gasket circle reaction based on the 4 optimization methods available in AutoPIPE Vessel.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;In summary one can easily observe how much difference in cost each of the methods can result to.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;Options 2 and 4 which are the higher cost options, lead to a much more safe and conservative design with significantly reduced hub stress but with 40%-55% cost increase.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;&lt;span style="color:#008000;"&gt;Options 1 and 3 result in more compact flanges with smaller hub length and flange diameter but at the cost of higher hub stress. &lt;/span&gt;&lt;br /&gt;&lt;span style="color:#008000;"&gt;Hence the optimization method provides a valuable iterative approach to arrive at the most optimum design based on the cost vs. performance criteria.&lt;/span&gt;&lt;/p&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 style="margin-left:60px;"&gt;Text&lt;/p&gt;
&lt;h1&gt;Answer:&lt;/h1&gt;
&lt;p style="margin-left:60px;"&gt;Body flanges can be a very expensive component of a pressure vessel particularly if the material of construction is expensive eg. nickel alloys or stainless steel. Hence performing an optimum flange design is critical for a cost effective solution.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;AutoPIPE Vessel flange design module offers several optimization methods eg. EN 13445 Annex. G, with compression rings, loose and bolt tensioning options.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/56525.2.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;There are 4 options available for optimization based on hub stress and gasket circle reaction optimizations and also another design method based on bolt load namely design, full or controlled bolt load.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Shown above are the results from a case study on the design of a body flange using the hub stress and gasket circle reaction based on the 4 optimization methods available in AutoPIPE Vessel.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;In summary one can easily observe how much difference in cost each of the methods can result to.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Options 2 and 4 which are the higher cost options, lead to a much more safe and conservative design with significantly reduced hub stress but with 40%-55% cost increase.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Options 1 and 3 result in more compact flanges with smaller hub length and flange diameter but at the cost of higher hub stress. &lt;br /&gt;Hence the optimization method provides a valuable iterative approach to arrive at the most optimum design based on the cost vs. performance criteria.&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/22464.1.png"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/22464.1.png" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
