TUBE SHEET CALCULATION

Tubesheet calculation as per ASME Section VIII Div 1 Appendix 41 hr = 22 mm hr = minimum required thickness of the EIH support W = 45 W = EIH support plate flanged extension bolt load for the gasket seating condition Wm1 = 45 Wm1 = EIH support plate flanged extension bolt load for operating conditions. hg = 58 mm hg = gasket moment arm, Sa = 52 Sa = allowable stress for the EIH support plate material at atmospheric temperature S = 64 S = allowable stress for EIH support plate material at design temperature G = 89 G = diameter of gasket load reaction Minimum required thickness of the EIH support plate

92.12773

83.04282 = 92.12773

p = mm p = minimum pitch of element holes d = mm d = diameter of holes in element pattern Calculate ligament efficiency = #DIV/0! h = mm h = thickness of the center of the EIH support plate

h/p

=

#DIV/0!

E* = E* = effective modulus of elasticity of EIH support plate in perforated region
