Precision seamless steel pipe is a high-precision steel pipe processed by cold rolling or cold drawing; the full name is: cold rolled or cold drawn precision seamless steel pipe. Due to the advantages of no oxide layer on the inner and outer walls of the precision seamless steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as Cylinders or oil cylinders are made of seamless pipes.

Cold-drawn precision seamless steel pipe is a precision cold-drawn seamless pipe used for mechanical structure and hydraulic equipment with high dimensional accuracy and good surface finish. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment, etc., cold-drawn seamless steel pipes are the first choice for machining manufacturing and parts manufacturing, which can greatly save machining time, improve material utilization, and help improve product quality.

Features of general seamless pipe

1. The main feature of general ordinary seamless steel pipes is that they have no welding seams and can withstand greater pressure. The product can be very rough cast or cold drawn.

2. The dimensions of the inner hole and outer wall of the cold drawn precision steel pipe have strict tolerances and roughness.

Features of cold drawn (rolled) precision steel pipes

1. The outer diameter is smaller;

2. High precision can be used for small batch production;

3. Cold-drawn (rolled) finished products have high precision and good surface quality;

4. The cross-sectional area of the steel pipe is more complicated;

5. The performance of the steel pipe is superior, and the metal is denser.
