Precision seamless steel pipe is a kind of high-precision steel pipe after cold rolling or cold drawing

Precision Seamless Steel Pipe is a cold-rolled or cold drawn after the treatment of high-precision steel; 

full name: cold-rolled or cold drawn precision Seamless Steel Tubes. 

Because the seamless Steel Pipe inside and outside the wall without oxide, high pressure without leakage, high precision, high finish, cold deformation, flaring, flattening crack-free, so mainly used to produce pneumatic or hydraulic components of products such as Cylinder or cylinder, are used seamless pipe. 

The chemical composition of precision seamless steel tubes are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. 

The difference between precision steel pipe and seamless steel pipe 

1, the obvious difference with the seamless steel pipe is: high dimensional accuracy, up to 0.05mm. 

2, Precision Steel Tube diameter surface finish, customers do not need to process can be used directly; and ordinary seamless steel pipe need to customer lathe, polishing and other processing. 

Precision seamless steel pipe Features 

1. Outer diameter smaller. 

2. High precision can do small batch production. 

3. Cold drawn high precision, good surface quality. 

4. Pipe cross-sectional area is more complicated. 

5. Pipe superior performance, metal is more dense.
