Precision spiral steel pipe is a high-precision steel pipe that is cold drawn or hot rolled. Because the inner and outer walls of the precision spiral steel pipe have no oxide layer, there is no high pressure, no leakage, high precision, high smoothness, no cold deformation, flaring, flattening, no cracks, etc., so it is mainly used to produce pneumatic or hydraulic components . The chemical composition of precision spiral steel pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
The difference between precision steel pipe and spiral steel pipe
1. The main feature of spiral steel pipe is that it has no welded joints and can withstand greater pressure. The product can be very rough casting or cold drawn.
2. Precision steel tubes are products that have appeared in recent years, mainly due to strict tolerances and roughness of the inner and outer wall dimensions.
