Structural Pipe Related Introduction And Specifications

1. Overview of structural pipe

For structural pipes, this standard applies to seamless steel pipes for general structures and mechanical structures, and the fluid seamless steel pipe standard applies to general seamless steel pipes that transport fluids. The main difference between it and structural seamless steel pipes is that the fluid seamless steel pipes are subjected to hydraulic tests or ultrasonic, eddy current, and magnetic flux leakage testing one by one. Therefore, in the standard selection of pressure pipeline steel pipes, fluid seamless steel pipes should not be used. Seamless steel pipes are expressed in terms of outer diameter and wall thickness. Thick-walled seamless steel pipes are mainly used for machining, coal mines, hydraulic steel, and many other purposes. The material of thick-walled seamless steel pipe is divided into 10#, 20#, 35#, 45# 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, etc. The classification of thick-walled seamless steel pipes-hot-rolled thick-walled seamless steel pipes, cold-rolled thick-walled seamless steel pipes, cold-drawn thick-walled seamless steel pipes, extruded thick-walled seamless steel pipes, pipe jacking. Structural stainless steel seamless steel pipe (GB/T14975-1994) is a hot-rolled (extruded, Expanded) and cold drawn (rolled) seamless steel tubes.
