what is the difference between Precision steel pipe and seamless steel pipe

Precision seamless steel pipe is a kind of high-precision steel pipe after cold drawing or hot rolling. Because the precision seamless steel pipe inner and outer wall without oxide layer precision seamless steel pipe, withstand high pressure and no leakage, high precision, high finish, cold bending deformation, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components Products such as cylinders or cylinders are made of seamless tubes. The chemical composition of precision seamless steel tubes is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
The difference between precision steel pipe and seamless steel pipe 1. The main feature of seamless steel pipe is that it has no welding seam and can withstand greater pressure. The product can be very rough cast or cold dial.
2. Precise steel pipe is a product that has emerged in recent years. It mainly has strict tolerances and roughness on the inner hole and outer wall dimensions.
Precision seamless steel pipe features 1. Smaller outside diameter.
2. High precision can be done in small batch production.
3. High-precision cold drawn products, good surface quality.
4. The transverse area of the steel tube is more complicated.
5. The steel pipe has better performance and the metal is denser.
