Test requirements for seamless A106 carbon steel pipes
Hydrostatic Test: Check that the test pressure produces a stress on the pipe wall equal to 60% of the specified minimum yield strength (SMYS) at room temperature. Maximum pressure must not exceed 2500 psi for NPS 3 and below and 2800 psi for larger sizes. The pressure is maintained for no less than 5 seconds.Mechanical test
Tensile test: NPS 8 and above acceptable transverse or longitudinal test Tensile Tests Less than NPS 8: Longitudinal Tests Only Flattening test: NPS 2 and above Bend Test (Cold): NPS 2 and belowHaihui Steel is the world leader in the supply of A106/SA106 pipe, stocking a full line of Grade B/C pipes in sizes ranging from NPS 1/2″ to NPS 36″ with nominal (average) wall thicknesses as specified in ANSI B36.10 Show. Other sizes of pipe may be supplied if the pipe meets all other requirements of this specification. Pipe ordered in accordance with this specification shall be suitable for bending, flanging, welding and similar forming operations. A full range of SA/A106 stock is available in Annexes 10 to 160, STD, XS, XXS. Size(mm):| OD(Out Diameter) | W.T(Wall Thickness) | L(Length) |
