Schedule Number = 1,000 x (P/S).

Where P = internal pressure, pounds-per-square-inch-gauge (PSIG) and S = allowable fiber stress (ultimate tensile strength of the steel in psi).
(2)

Schedule Number = (1,000)(P/S).

Where,
P = the internal working pressure, psig.
S = the allowable stress (psi) for the material of construction at the conditions of use.
(3)

A schedule number indicates the approximate value of

Sch. = 1000 P/S

where

P = service pressure (psi)

S = allowable stress (psi)
