OEM/ODM China Aisi 4140 Steel Plate - G550 Pre-coated DX51D SPCC Galvanized Steel Coil – XINXIN PENGYUAN Detail:
Seamless steel pipe is perforated by the whole round steel pipe, there is no weld on the surface of the steel pipe, called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking, etc. According to the shape of the section, seamless steel pipe can be divided into two kinds: round pipe and special-shaped pipe. Special-shaped pipe has square, oval, triangle, hexagonal, melon seed shape, star shape and many complex shapes with wings. The maximum diameter is 900mm, and the minimum diameter is 4mm. According to different uses, there are thick wall seamless steel pipe and thin wall seamless steel pipe. Seamless steel pipe is mainly used for petroleum geology drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high precision structural steel pipe for automobile, tractor and aviation.
The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn , Sulphur S, Phosphorus P, Chromium Cr, compared with solid steel such as round steel, seamless steel pipe has lighter weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and machinery Components.
