Precision seamless steel pipe is a kind of high-precision steel pipe after cold rolling; full name: cold-rolled precision seamless steel pipe. Because the inner and outer walls of the precision seamless steel pipe have no oxide layer, can withstand high pressure, no leakage, high precision, high finish, cold bending, deformation, flaring, flattening and no cracks, they are mainly used to produce pneumatic or hydraulic components. The cylinders or cylinders are all seamless. 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 obvious difference from the seamless steel pipe is: high dimensional accuracy, which can reach 0.1mm.
2. The surface roughness of the inner and outer diameter of precision steel pipe is high, and customers can use it without processing; and ordinary seamless steel pipe requires the customer to process the lathe, polishing, etc.
Precision seamless steel pipe features
1. The outer diameter is smaller.
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.
