A106 seamless steel pipe belongs to the American standard steel pipe. A106 includes A106-A and A106-B. The former is equivalent to the domestic 10# material, and the latter is equivalent to the domestic 20# material. It belongs to the ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes: cold drawing and hot rolling. In addition to the different production processes, the two are different in precision, surface quality, minimum size, mechanical properties, and organizational structure. It is widely used in various industries such as petroleum, chemical industry, boilers, power stations, ships, machinery manufacturing, automobiles, aviation, aerospace, energy, geology, construction and military industry.
