UHX-13.5.10 Step 10:

Shell Axial Membrane Allowable Stress: = Ss * Esw = 1406.14 * 0.70 = 984.30 kgf/cm^2

Axial Membrane Stress in Shell [Sigmasm_ax]: = ao^2/((Ds+ts)*ts)* [Pe + (Rhos^2-1)(Ps-Pt)]+ as^2*Pt/((Ds+ts)*ts) = 134.000^2/((324.000 +10.0000 )*10.0000 )* [1.65 + (1.209^2-1) (3.00 -1.00 )] + 162.000^2*1.00 /((324.00 +10.0000 ) * 10.00 ) = 21.6743 kgf/cm^2

UHX-13.5.11 Step 11:

Note: For a given Shell thickness of 10.000 mm, the minimum Shell length adjacent to the tubesheet should be 102.458 mm

The Shell Membrane Stress due to Joint Interaction [Sigmasm]: = ao^2/((Ds+ts)*ts)[Pe + (Rhos^2-1)(Ps-Pt)]+ as^2*Pt/((Ds+ts)*ts) = 134.000^2/((324.000 +10.0000 )*10.0000 )[1.65 + (1.209^2-1) (3.00 -1.00 )] + 162.000^2*1.00 /((324.00 +10.0000 ) * 10.00 ) = 21.6743 kgf/cm^2

The Shell Bending Stress due to Joint Interaction [Sigmasb] = 6*ks/ts^2{betas[deltaS*Ps + as^2*PstarS/(Es*ts)] + 6(1 - nu*^2)/(E*)(ao/h)^3(1 + h*betas/2)[Pe(Zv + Zm*Q1) + 2/ao^2* Zm * Q2 ]} = 6 * 11640625 /10.0000^2{0.031 [ 0.001 * 3.000 + 162.0000^2 * 0.0000 /(20206290 ) ] + 6(1 - 0.26^2)/(1007283 )(134.00 /35.00 )^3(1 + 35.00 * 0.03 /2)[ 1.6 ( 0.191 + 0.770 * -0.088 ) + 2/134.00^2* 0.770 * -35.920 ] } = 36.9946 kgf/cm^2
