Structural pipe
Structural pipe, suitable for general structure, mechanical structure with seamless steel pipe, fluidseamless steel pipeThe standard applies to the general seamless steel pipe for conveying fluid. The main difference between it and the structural seamless steel pipe is that the fluid seamless steel pipe is subjected to hydraulic test or ultrasonic, eddy current and magnetic flux leakage detection. Therefore, in the standard selection of pressure pipe steel pipe, it is not appropriate to use fluid seamless steel pipe. Seamless steel pipe means outer diameter, wall thickness, thick wall seamless steel pipe is mainly used for machining, coal mine, hydraulic steel, and other purposes. The material of thick wall seamless steel pipe is divided into 10#, 20#, 35#, 45# 16Mn, 27SiMn, 12Cr1MoV,10CrMo910,15CrMo,35CrMoWait. 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, and pipe jacking. Structural stainless steel seamless steel pipe (GB/T14975-1994) is widely used in chemical, petroleum, textile, medical, food, machinery and other industrial corrosion-resistant pipes and structural parts and parts of stainless steel made of hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel pipe.
