b31gacl: ASME B31G. Allowable corrosion length in pipe

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.

d

nominal outside diameter of the pipe, [inch]. 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.

# NOT RUN {
 b31gacl(1093, 910, 30, .438, .1, 7.5)
 # [1] Inf  # [inch] - corrosion is low, no limit for the corroded area length

 # [1] 2.018  # [inch] - finite allowed length of the corroded area
