"WebbWorking pressure is a term used to describe the maximum allowable pressure a pipe may be subjected to while in-service. Barlow's formula can be used to calculate the maximum allowable pressure by using design factors as. Pa = 2 Sy Fd Fe Ft t / do (3) where. Pa = maximum allowable design pressure (psig) Sy = yield strength (psi) Fd = design factor. " - Pipe safety factor
