Large Diameter Precision Bright Seamless Steel Pipe

Precision steel tubes are a type of tubing that is cold drawn or...Hot RolledA high-precision steel pipe material after treatment. Due to its advantages such as no oxidation layer on the inner and outer walls, no leakage under high pressure, high precision, high smoothness, no deformation during cold bending, no cracks during expansion or flattening, it is mainly used for manufacturing products like pneumatic or hydraulic components, such as cylinders, which can be either seamless or welded pipes.

Precision steel tubes with high dimensional accuracy, inner and outer tube surfacesSurface finish，Steel pipeAfter heat treatment, both the inner and outer surfaces are free of oxidation film. The steel pipes have no cracks after expansion and flattening, do not deform during cold bending, and can withstand high pressure. They are capable of various complex deformations and can be subjected to deep mechanical processing.

Main steel pipe grades produced: 10#, 20#, 35#, 45#, 40Cr, 42CrMo, 16Mn, etc.

Negotiable for supply of other brands as well.Precision Seamless Steel Pipe。

Key production bases for precision seamless steel tubes: Shandong, Jiangsu, Chengdu, Tianjin, Hebei, etc.

The chemical composition of precision steel pipes includes carbon (C).SiliconSilicon (Si), Manganese (Mn), Sulfur (S), Phosphorus (P)ChromeCr。

National standard for precision steel tubes: GB/T699-2008, National standard for precision steel tubes: GB/T3639-2008, and possibly also precision steel tubes for structural use under GB/T8162-2008.
