Variable list
Nominal wall thickness of tubesheet at the tubed area, without considering of gasket grooves or relief grooves.
Local reduction of thickness at the periphery of the tubesheet
A local reduction of thickness at the periphery of the tubesheet for a gasket groove or a relief groove is permitted, provided that the remaining analysis thickness, ea,p , is at least equal to 0,8 times the assumed thickness, e , of the tubesheet (see Figure 13.4.2-1):
