Ds [in] - inside diameter of shell nt [in] - nominal shell wall thickness Treq [in] - required shell wall thickness sca [in] - shell corrosion allowance

Sn [psi] - allowable stress E - nozzle efficiency

Do [in] - outside diameter of nozzle Nwall [in] - nominal wall thickness of nozzle Lp [in] - exterior projection of nozzle Ip [in] - interior projection of nozzle nca [in] - nozzle corrosion allowance UTP [%] - undertolerance allowance Pn [psi] - interior pressure

Sp [psi] - allowable stress of repad te [in] - repad thickness Dp [in] - outside diameter Leg41 [in] - fillet size Leg42 [in] - fillet size Leg43 [in] - fillet size LegG [in] - depth of groove

UT [in] = Rn [in] =

ti [in] = h [in] =

tn [in] = d [in] =


TreqN [in] = (Pn*Rn)/(Sn*E - 0.6*Pn)+nca ~~ required minimum thickness

CheckTreqN =

K13

Typically E1=1

K16

Use nt from the corresponding head or pipe and shell program

K17

Use one of the following based on nozzle location: nozzle in pipe/shell - See Treq from pipe and shell program nozzle in head - See Treq from corresponding head program
