Cold-drawing or cold-rolled precision seamless steel pipe Shandong Seamless Steel Tube Plant Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-83) is used for mechanical structure, hydraulic equipment, high dimensional accuracy and good surface finish cold drawn or cold rolled Precision seamless steel pipe. The use of precision seamless steel pipe manufacturing machinery structures or hydraulic equipment, etc., can greatly reduce the mechanical processing time, improve the material utilization, and help improve product quality.
Precision steel pipe is a kind of high-precision steel pipe material processed by cold drawing or cold rolling. Due to the fact that the outer and inner walls of the precision steel pipe are free of oxide layers, withstand high pressure, no leakage, high precision, high finish, no distortion due to cold bending, no flaring, no flat cracks, etc., they are mainly used for the production of pneumatic or hydraulic components such as cylinders or The cylinders can be seamless pipes or welded pipes (after cold rolling).
Characteristics of cold drawn (rolled) precision steel pipe
1. The outer diameter is smaller.
2. High precision for small batches
3. Cold-drawn (rolled) finished product with high precision and good surface quality.
4. The transverse area of ​​the steel tube is more complicated.
5. The performance of the steel pipe is superior, and the metal is comparatively dense.
