&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;Where to input extra cladding thickness &amp;nbsp;on tubesheets?&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;Example:&lt;/p&gt;
&lt;p style="margin-left:90px;"&gt;input 3.2 mm of cladding on shell and tubes side. But we want to increase cladding on tubesheet until 9.5 in shell side and 8 on tube side. How can I do this? Should I input those values in corrosion field? (if I do that hfl is bigger than hp on floating tubesheet).&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;The clad can be taken into account as a corrosion allowance, but this is just a workaround (there is an enhancement in the backlog: TFS#72825).&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;hfl is bigger than hp in the model because the corrosion (tube side) is not applied on hfl (thickness of the flanged extension), see below the detail of the calculation:&lt;br /&gt;thickness of the flanged extension : hfl&lt;br /&gt;thickness at the periphery : hp&lt;br /&gt;thickness of the tubesheet: hnew = 329 mm&lt;br /&gt;Corrosion Shell Side: CAss = 9.5 mm&lt;br /&gt;Corrosion Tube Side: CAts = 8 mm&lt;br /&gt;Extra thickness (machining extension): hg = 8 mm&lt;br /&gt;Extra thickness (recessed face): hf = 5 mm&lt;br /&gt;hfl = hnew - hg - hf - CAss = 329 -8-5-9.5 = 306.5 mm&lt;br /&gt;hp = hnew - hg - CAts - CAss = 329 -8-8-9.5 = 303.5 mm&lt;/p&gt;
