ASTM A106 is a standard specification issued by the American Society for Testing and Materials (ASTM) that outlines the requirements for seamless carbon steel pipes, which covers various grades, such as A, B, and C.
ASTM A106 seamless steel pipe includes two processes: cold drawing and hot rolling. In addition to different production processes, there are also differences between the two in terms of accuracy, surface quality, minimum size, mechanical properties, organizational structure, etc. Widely used in petroleum, chemical industry, boilers, power stations, shipbuilding, machinery manufacturing, automobiles, aviation, aerospace, energy, geology, construction and military industries.
