What is the longitudinal stress psi of a 600 psig steam head

What is the longitudinal stress (psi) of a 600 psig steam header made from 16 in. ID pipe with wall thickness 0.5 in.?

Solution

FROM Given Data,

Pinternal=600PSIG,

Internal dia.=16In

Thickness ,t-0.5 In

longitudinal stress=(Pi+Di)/(4*t)

longitudinal stress=(600*16)/(4*0.5)

longitudinal stress=4800 PSIG
