Manufacturing, characteristics, and applications of seamless steel pipe 279

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 pipe is favored by the market for its unique performance and wide range of applications.

First, the manufacturing process of seamless steel pipe 279

The manufacturing process of seamless steel pipe 279 mainly includes perforation, rolling, heat treatment, straightening, sizing, flaw detection, and other processes. Perforation is to pierce a solid tube blank into a hollow capillary tube, which is the first step in the production of seamless steel pipes. Next, the capillary tube goes through the rolling process, and through continuous rolling, extrusion, and diameter 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 and at the same time improve the mechanical properties and corrosion resistance of the steel pipe. The straightening and sizing process ensures the straightness and dimensional accuracy of the steel pipe. Finally, the steel pipe goes 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.
