ASTM A106 carbon steel seamless pipe

ASTM A106 carbon steel seamless pipe can be divided different types on the basis of different classification standards. According to diverse production processing, it is divided into cold draw steel pipe, cold rolled seamless steel tube and hot rolled steel pipe or hot expansion steel pipe. While cold rolled pipe has better dimensional accuracy than hot rolled. And according to different applications, it also can be divided into low pressure steel pipe, medium pressure seamless steel tube, high pressure boiler tube, alloy steel pipe and petroleum cracking pipe for construction and pipe line.
