How to distinguish precision seamless steel pipes and industrial seamless steel pipes？

There are significant differences between precision seamless steel pipes and industrial seamless steel pipes in many aspects, and these differences can be effectively distinguished.

First of all, from the perspective of manufacturing process and raw materials, precision seamless steel pipes are usually obtained by cold drawing or hot rolling. The raw materials are stainless steel tube blanks, that is, bare pipes. After cold drawing or cold rolling, annealing and pickling, they become Finished product. The manufacturing process of industrial seamless steel pipes may involve more types of processes, and their raw materials may also be different.

Secondly, from the perspective of dimensional accuracy and surface finish, precision seamless steel pipes have higher dimensional accuracy, usually reaching 0.05mm, and their inner and outer diameters have high surface finish, so users can use them directly without processing. In comparison, the dimensional accuracy and surface finish of industrial seamless steel pipes may be slightly inferior.

In addition, there are also differences in the outer diameter dimensions of the two. The outer diameter of precision seamless steel pipes is generally smaller.

Finally, from the perspective of use and performance, precision seamless steel pipes are mainly used to produce products that require high precision and smoothness, such as pneumatic or hydraulic components, with dense metal and superior performance. Industrial seamless steel pipes are widely used in manufacturing structural parts and mechanical parts due to their high strength, high corrosion resistance, good plasticity and weldability.
