&lt;p&gt;Question:&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Why effective diameter formula is different in operating and hydrotest condition tube side compared to hydrotest condition shell side?&lt;/p&gt;
&lt;p&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;Answer:&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;In&amp;nbsp;operating and hydrotest condition (tube side) cases the end brackets (Front End &amp;amp; Rear End) will be connected to the tubesheet. Hence taking the bolting loads, bracket weights and external loads while performing the calculation. &lt;/span&gt;&lt;/span&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;Hence effective diameter De = (Ds+Gc)/2, Where Ds = Inside shell diameter &amp;amp; Gc = Channel gasket load diameter&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;Whereas, In hydrotest condition (shell side) case the end brackets (Front End &amp;amp; Rear End) are not present. Hence not&amp;nbsp;taking&amp;nbsp;any effect of bolting loads, bracket weights and external loads while performing the calculation.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="JLqJ4b ChMk0b"&gt;&lt;span class="Q4iAWc"&gt;Hence effective diameter De = Ds&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
