ASME B31G. Safe maximum pressure for the corroded area of pipe — b31gsap • pipenostics

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.

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

# safe pressure is lower than design pressure due corrosion:
b31gsap(877, 24, .281, .08, 15)
