STEEL PIPE & FITTINGS SUPPLY

The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel can be divided into hot-rolled seamless steel , cold-rolled seamless steel , cold-drawn seamless steel , extruded seamless steel , and pipe jacking. . According to different purposes, there are thick-walled seamless steel and thin-walled seamless steel . Seamless steel are mainly used as petroleum geological drilling , cracking for petrochemical industry, boiler , bearing , and high-precision structural steel for automobiles, tractors, and aviation.
A steel pipe that is seamless along the perimeter of its cross-section. According to different production methods, it is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking, etc., all of which have their own process regulations.
The materials include ordinary and high-quality carbon structural steel (Q215-A~Q275-A and No. 10~50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid-resistant steel, etc.
According to the purpose, it is divided into two categories: general purpose (for water transmission, gas pipelines and structural parts, mechanical parts) and special purpose (for boilers, geological exploration, bearings, acid resistance, etc.)
