Thickness Due to Internal Pressure (TR): = (P*(L+T)*M)/(2*S*E+P*(M-0.2)) per Appendix 1-4 (d) = (20.00*96.1750*1.6720)/(2*20000.00*1.00+20.00*(1.6720-0.2)) = 0.0803 in.

Max. All. Working Pressure at Given Thickness (MAWP): = (2*S*E*(T-CA))/(M*(L+T)-(T-CA)*(M-0.2)) per Appendix 1-4 (d) = (2*20000.00*1.00*(0.1125))/(1.6720*96.1750-(0.1125)*(1.67-0.2)) = 28.01 psig

M factor for Torispherical Heads ( New & Cold ):M = (3+SQRT(L/r))/4 per Appendix 1-4 (b & d)M = (3+SQRT(96.000)/(7.0000)))/4M = 1.6758

Maximum Allowable Pressure, New and Cold (MAPNC): = (2*SA*E*T)/(M*(L+T)-T*(M-0.2)) per Appendix 1-4 (d) = (2*20000.00*1.00*0.1750)/(1.6758*96.1750-2*0.1750*(1.68-0.2)) = 43.50 psig

Actual stress at given pressure and thickness (Sact): = (P*(M*(L+T)-(T-CA)*(M-0.2)))/(2*E*(T-CA)) = (20.00*(1.6720*96.1750-(0.1125)*(1.6720-0.2)))/(2*1.00*(0.1125)) = 14279.15 psi

Required Thickness Calculation:

First iteration:

Elastic Buckling Stress (Se): = C1 * Et * (t/r) = ( 0.601 * 0.285E+08 * 0.008) = 128801.602 psi

A = 0.5 * D - r = 40.825 in.B = L - r = 89.000 in.BETA = COS(A/B) = 1.094 rad.PHI = SQRT(L*t) / r = 0.320 rad.C = A / COS(BETA-PHI) = 57.106 in.Re = C + r = 64.168 in.

Buckling Internal Pressure (Pe): = (Se * t) / (C2 * Re * ((0.5 * Re / r) - 1.0)) = (128801.6*0.053)/(1.250*64.168*((0.5*64.168/7.062)-1.0)) = 24.090 psig

Yield Internal Pressure (Py): = (Sy * t) / (C2 * Re * ((0.5 * Re / r) - 1.0)) = (34800.0*0.053)/(1.250*64.168*((0.5*64.168/7.062)-1.0)) = 6.509 psig

Knuckle Failure Internal Pressure (Pck): = 0.408 * Py + 0.192 * Pe = 0.408 * 6.509 + 0.192 * 24.090 = 7.281 psig

Allowable Pressure (Pa): = Pck / 1.5 = 7.281 / 1.5 = 4.854 psig
