Precision seamless steel pipe is a cold drawn or hot-rolled after treatment of a high-precision steel pipe. As the precision seamless steel pipe inside and outside the wall of non-oxidized layer of precision seamless steel pipe, to withstand high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc., is mainly used to produce pneumatic or hydraulic components Of products, such as cylinders or cylinders, are made of seamless tubes. Precision seamless steel pipe chemical composition of carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.


 


Difference between precision steel pipe and seamless steel pipe


1, the main features of seamless steel pipe is no welding seam, can withstand greater pressure. The product can be very rough as-cast or cold-drawn parts.


2, precision steel pipe in recent years there are products, mainly within the hole, the outer wall size has a strict tolerance and roughness.


 


Characteristics of precision seamless steel tube


1. Smaller outer diameter.


2. High precision can do small batch production.


3. Cold drawn finished high precision, good surface quality.


4. Tube cross-sectional area is more complex.


5. Pipe performance is better, more dense metal.
