Seamless Pipe
Factory Supply Galvanized Seamless Steel Pipe/Tube
Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to the production method, the 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 and so on. According to the section shape, the seamless steel pipe is divided into two kinds of round and shaped, shaped pipe has square, oval, triangle, hexagonal, melon seed, star, fin tube and many complex shapes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick wall seamless steel pipes and thin wall seamless steel pipes. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and high-precision structural steel pipe for automobiles, tractors and aviation.
1.Carbon Steel Seamless Steel Pipe and Round Steel and Other Solid Steel, in the Bending and Torsional Strength of the Same Weight is Lighter, is a Kind of Economic Section of Steel, Widely Used in the Manufacture of Structural Parts and Mechanical Parts, Such As Oil Drill Pipe, Automobile Drive Shaft, Bicycle Frame and Construction Used in Steel Scaffolding.
2.Seamless Carbon Steel Pipe / Tube used for transporting gas and liquid objects such as oil and gas, could meet the low and high pressure requirement.
3.The bearing capacity of the product is large, and it is not easy to deformation.Multiple processing equipment multiple processing procedures.cutting surface without burrs.
