[Copy] ASME SA-106/SA-106M-2015 Carbon steel pipe

Short Description:

ASTM A106 GrB. Seamless steel tubes belong to American standard steel tubes, A106 includes A106-A, A106-B. The former is equivalent to the domestic 10# material, while the latter is equivalent to the domestic 20# material. Belongs to ordinary carbon steel series, is one of the commonly used materials. ASTM A106 Seamless steel tubes include both cold drawing and hot rolling processes. In addition to the production process, the two are different in accuracy, surface quality, minimum size, mechanical properties, organizational structure. It is widely used in petroleum, chemical industry, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry and other industries.

ASTM A106Gr.B Seamless steel tube is a kind of low carbon steel widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. A106-b steel pipe is equivalent to China’s 20#seamless steel pipe, in accordance with ASTM A106/A106M high temperature operation carbon steel seamless steel pipe standard, grade B.

For transverse strip tests, a deduction for each 1/32-in. (0.8-mm) decrease in wall thickness below 5/16 in. (7.9 mm) from the basic minimum elongation of the following percentage shall be made		1.25		1.00		1.00
A The minimum elongation in 2 in. (50 mm) shall be determined by the following equation:
e=625000A 0.2 / U 0.9
for inch-pound units, and
e=1940A 0.2 / U 0.9
for SI units,
where: e = minimum elongation in 2 in. (50 mm), %, rounded to the nearest 0.5%, A = cross-sectional area of the tension test specimen, in.2 (mm2), based upon specified outside diameter or nominal specified outside diameter or nominal specimen width and specified wall thickness, rounded to the nearest 0.01 in.2 (1 mm2). (If the area thus calculated is equal to or greater than 0.75 in.2 (500 mm2), then the value 0.75 in.2 (500 mm2) shall be used.), and U = specified tensile strength, psi (MPa).

Test Requirement

In addition to ensuring chemical composition and mechanical properties, hydrostatic tests are performed one by one, and flaring and flattening tests are performed. . In addition, there are certain requirements for the microstructure, grain size, and decarburization layer of the finished steel pipe.
