Heat treatment processing of black steel seamless pipes is widely used, so it is necessary to understand the safe operation of heat treatment processing, so as to ensure their own safety and also ensure product quality.

The ssaw steel pipe adopts the advanced double-sided submerged arc welding process. When welding, it should be ensured that the weld bead has no impurities, no misalignment, and no welding defects such as incomplete penetration.

In the production process of cold drawn seamless tubing, there are work hardening and hydrogen embrittlement, which are the main reasons for the cracking of cold drawn seamless tubing.

The external factors that affect the compressive strength of seamless pipes are temperature, strain rate, and in-situ stress.

We choose the welded pipe because of its corrosion resistance and long service life, but will the welded pipe have a long service life? This is not necessarily the case. Only by understanding the performance of the welded pipe and making it reasonably used can its life be maximized.

With the increasing market demand, the advantages of seamless pipes have also been stimulated, but there are also many fake and shoddy products on the market, everyone must be careful when choosing.
