Manufacturing, characteristics, and applications of 279 seamless steel pipe

Seamless steel pipe, as an important industrial raw material, is widely used in petroleum, chemical industry, natural gas, heat, water supply, drainage, steam, electricity, and other fields. Among them, 279 seamless steel pipes have been favored by the market for their unique performance and wide application fields.

First, the manufacturing process of 279 seamless steel pipe
The manufacturing process of 279 seamless steel pipe mainly includes perforation, rolling, heat treatment, straightening, sizing, flaw detection, and other processes. Perforation is to pierce the solid tube into a hollow rough tube, which is the first step in the production of seamless steel pipes. Then, the rough tube undergoes the rolling process, and through continuous rolling, extrusion, and expansion, the thickness and diameter of the tube wall meet the specified requirements. The heat treatment process is to eliminate the stress generated by the steel pipe during the rolling process while improving the mechanical properties and corrosion resistance of the steel pipe. The straightening and sizing processes ensure the straightness and dimensional accuracy of the steel pipe. Finally, the steel pipe passes through the flaw detection process to check the internal quality and surface defects of the steel pipe to ensure that the quality of the steel pipe meets the standards.
