ASTM A106B in stock

ASTM Specification A106B covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending, flanging and similar forming operations. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface finish standards are outlined in the specification.

ASTM A106B Testing Requirements for seamless A106 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. ASTM A106B Mechanical Tests:

1) Tensile Test: Either transverse or longitudinal are acceptable for NPS 8 and larger

2) Tensile tests smaller than NPS 8: Longitudinal testing only

3) Flattening Test: NPS 2 and larger

4) Bending Test (cold): NPS 2 and under

ASTM A106B 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.
