The difference between precision seamless steel tube and cold drawn seamless steel tube
Precision seamless steel tube 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 cylinders.
Difference between precision seamless steel tube and cold drawn seamless steel pipe
1, the main features of seamless steel tube 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.
