Testing Requirements for seamless A106 carbon steel pipe

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations.

ASTM A106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

Testing Requirements for seamless A106 carbon steel pipe

• 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.

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
