Precision pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Because the inner and outer wall of the precision steel tube are free of oxide layer, high pressure without leakage, high precision, high smoothness, cold bending is not deformed, flaring, flattening crack-free and so a little, so mainly used to produce pneumatic or hydraulic components of products such as cylinder, can be seamless, but also welded pipe. The chemical composition of precision steel carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The difference between precision steel pipe and seamless steel pipe
1, The main feature of seamless steel pipe without welding seam, can withstand greater pressure. Products can be very rough cast or cold dial.
2, Precision steel tube is the product of recent years, mainly in the hole, the outer wall size has strict tolerances and roughness.
