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. Raw materials The materials used for ASTM A106 standard specification shall be applicable for bending, flanging, or the similar forming processes. In case the steel material is to be welded, the welding process supposed to be suitable for this grade of ASTM A106, and applicable for the high temperature working environment. Where there is a superior or a higher grade for the ASTM A106 steel pipe is required, the standard has a optional specification for the supplementary requirements, for the pipes that used this standard. More over, these supplementary specification asked for the additional test, when the order is to be placed. Standards referred for making ASTM A106 pipes References ASTM standards: a. ASTM A530/ A530M This is the standard specification for the common requirements of the carbon, and alloy pipes. b. E213 The standard for the Ultrasonic Examination test c.

SSPC-SP 6 The standard specification for the surface. 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.
