Description

Calculate allowable length of the corroded area in the pipe.

Usage

b31gacl(dep, maop, d, wth, depth, l)

Arguments

dep

design pressure of the pipe, [PSI]. Type: assert_double.

maop

maximum allowable operating pressure - MAOP, [PSI]. Type: assert_double.

wth

nominal wall thickness of the pipe, [inch]. Type: assert_double.

depth

measured maximum depth of the corroded area, [inch]. Type: assert_double.

l

measured maximum longitudinal length of the corroded area, [inch]. Type: assert_double.

Value

allowable length of the corroded area in the pipe, [inch]. Type: assert_double.
