ASTM A106

ASTM A106 carbon steel pipe is American standard of seamless steel tube including A106-A and A106B. The former is equivalent to 10# material in China; the latter is equal to 20# material. ASTM A106 is one of common used material and belongs to the ordinary carbon steel. Moreover, ASTM A106 carbon steel pipe contains two different technologies: cold-drawing and hot rolling. Apart from various production processes, both differ in accuracy, surface quality, minimal size, mechanical properties and structures. Meanwhile, ASTM A106 has a wide application in petroleum, chemical industry, boiler, power station, ships, machinery manufacturing, automotive, aviation, aerospace, energy, geology, architecture and military industry etc..
