ASME B31G. Safe maximum pressure for the corroded area of pipe

Description

Calculate safe maximum pressure for the corroded area of pipe.

Usage

b31gsap(dep, d, wth, depth, l)

Arguments

dep

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

d

nominal outside diameter of pipe, [inch]. Type: assert_double.

wth

nominal wall thickness of 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

Safe maximum pressure for the corroded area of pipe, [PSI]. Type: assert_double.

Examples

 library(pipenostics)

 b31gsap(1093, 30, .438, .1, 7.5)
 # [1] 1093  # [PSI], safe pressure is equal to design pressure

 b31gsap(877, 24, .281, .08, 15)
 # [1] 690   # [PSI], safe pressure is lower than design pressure due corrosion
