ASTM A106 Grade B Pipe Dimensions Schedule
The standard covers pipe sizes in NPS (National Standard Straight) from 1/8 inch to 48 inch (10.3mm DN6 – 1219mm DN1200), meanwhile complied the nominal wall thickness of the standard ASME B 36.10M. For other sizes out of the ASME B 36.10M is also allowed to use this standard specification.

Grade B Seamless Pipe
ASTM A106 standard specifications for the seamless steel pipe have three grades, that is ASTM A106 Gr. A, Grade. B and C, with the higher grade material, the strength performance is better.

Test Methods
The test methods for the ASTM A106 A, B, C are the flattening tests, hydrostatic test, nondestructive electric test, Ultrasonic test, eddy current test, flux leakage test, these test procedures shall be notified or discussed with client to confirm what kind of test will be applied.
