Through continuous improvement of service competitiveness, won the praise of the market. Song style; precision steel pipe is a high precision steel tube material after cold drawing or hot rolling. Precision steel pipes are mainly used for the production of pneumatic or hydraulic components, such as cylinders or cylinder products, they can be seamless or welded, but most of them are precision seamless steel. Precision pipe has the advantages of high outer surface of pipe after heat treatment, no flattening crack, cold bending deformation, high pressure resistance, and various complex deformation and mechanical processing. Deep processing. It mainly produces steel pipe grades 10, 20, 35 and so on. Precision steel pipe;

According to a series of formulas, the theoretical weight of steel pipe is calculated: W=(D-S)*S*0.02466, in which W=the weight of steel pipe per meter; S=the nominal wall thickness of steel pipe; D=the nominal outer diameter of steel pipe; the surface quality of bright pipe I is clean, oxide-free, crack-free, folding, rolling, scarring, separating layer and stripe.
