Calculate safe maximum pressure for the corroded area of pipe.

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

Arguments

dep

design pressure of the pipe, [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

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

Examples

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

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