Testing Requirements for seamless ASTM Q179/SA179 carbon steel pipe
(1)Hydrostatic Testing:
Inspection test pressures produce a stress in the pipe wall equal
to 60% of specified minimum yield strength (SMYS) at room
temperature. Maximum pressures are not to exceed 2,500 psi for NPS
3 and under, and 2,800 psi for the larger sizes. Pressure is
maintained for no less than 5 seconds.
(2)Mechanical Tests:
Tensile Test: Either transverse or longitudinal are acceptable for
NPS 8 and larger
Tensile tests smaller than NPS 8: Longitudinal testing only
Flattening Test: NPS 2 and larger
Bending Test (cold): NPS 2 and under
