Cold Rolled Steel Pipe BK BKS Cold Rolled Steel Tube
New Gapower Metal is professional manufacturer of hydraulic steel pipe.With an annual production of 10,000 tons of high precision seamless steel tube.
Sample characteristic Introduction
Cold Rolled Steel Pipe BK BKS Cold Rolled Tube is a kind of high-precision steel pipe material after cold rolled treatment. Precision steel pipes have high dimensional accuracy, high internal and external surface finish. After heat treatment, the internal and external surfaces of the steel pipes are free of oxide film. The steel pipes are flared and flattened without cracks, cold bending without deformation, and can withstand high pressure, and can perform various complex deformation and mechanical deep processing.
Cold Rolled Steel Pipe BK BKS Cold Rolled Tube inner and outer diameter tolerance can be accurate to ±0.1mm, in order to ensure the same bending and torsional strength, light weight, so widely used in manufacturing precision machinery parts. Precision steel pipe can save the waste of raw materials, improve the efficiency of mechanical processing, reduce processing procedures, improve production and material utilization rate, and help to improve product quality, reduce costs, and improve economic.
Advantages
2.No leakage under high pressure;
3.High precision;
4.High finish with smooth surface
5.No deformation during cold bending, flaring, flattening and no cracks.
