![]() The tolerances (permissible variations) for outside diameter of ASTM A106 pipe are specified in below table. Generally, pipes ≤ 4″ may be weighed in convenient lot pipe larger than 4″ shall be weighed separately. The mass of any length of pipe shall not vary more than 10% over and 3.5% under that specified in ASME B36.10M. Dimensions, Weights & Permissible Variations Testing and InspectionĬhemical analysis, tensile test, bending test, flattening test, hydrostatic test, nondestructive electric test (NDE) which includes ultrasonic test and eddy current testing, dimensional inspection & visual examination. *EL-2: the minimum elongation when standard round 2″ gauge length test specimen is used. *EL-1: basic minimum elongation transverse strip tests, and for all small sizes tested in full section. *T.S min.: tensile strength, minimum Y.S min.: yield strength, minimum. The sum of Cr, Cu, Mo, Ni, and V shall not exceed 1%. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200☏ or higher. When required, it shall be heat treated at a temperature of 1200☏ or higher. Hot finished pipe need not be heat treated. ASTM A106 seamless pipe shall be manufactured by the hot finished or cold drawn process. ![]() The pipe shall be made from killed steel with the primary melting process being open-hearth, basic-oxygen, or electric furnace, possibly combined with separate degassing or refining. Shijiazhuang Metalsin maintains a huge stock of ASTM A106 Gr.B seamless carbon steel pipes in 1/2″ to 36″ with wall thickness of SCH 40, SCH 80, XS, SCH 160, etc. The seamless pipe shall be suitable for bending, flanging, coiling and other similar forming operations, and for welding. There are 3 grades available: Grade A, Grade B, and Grade C. Pipe having other dimensions can also be furnished under this standard provided such pipe complies with all other requirements of this specification. It covers pipes sized from NPS 1/8 to NPS 48 with nominal wall thickness as given in ASME B36.10M. ASTM A106, identical with ASME SA-106, is the standard specification for carbon steel seamless pipe for high temperature service.
