Product Description
ASTM A106 Seamless Carbon Steel Pipe

ASTM A106 seamless pressure pipe (also known as ASME SA106 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.

ASTM A106 Grade B pipe is equivalent to ASTM A53 Grade B and API 5L B on chemical position and mechanical properties, in general use carbon steel and yiled strength minimum 240 MPa, tensile strength 415 Mpa.

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)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
