TEMA Tubesheet Allowable Stress Values
TEMA Tubesheet Allowable Stress Values
(OP)
TEMA RCB-7.132 Defines S as the ‘Code' (ASME VIII) allowable stress in tension for tubesheet material metal temperatures’. Some alloy materials, such AISI 316, have stress values listed in the Code greater than 66% of yield and less than 90% of yield (ASME II Part D Table1A Note G4), is it permissible to use these higher design stresses for S or should the tubesheet be designed to reduce the amount of deformation by using the lower values?
Would this be different for a U tube exchanger subject to no flange moments or an exchanger with expanded tubes only?
Thanks
