Seamless steel pipe characteristics and production process
Nov 22, 2018

The seamless steel pipe is a long section of steel with a hollow section and no seams around it. Generally, the thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost. Moreover, the process of the product determines its limited performance, and detection and shaping must be processed offline. Therefore, it embodies its superiority in high-pressure, high-strength, mechanical structural materials.


Combined with its performance characteristics, the current seamless steel pipe is mainly used in fluid conveying pipes, boiler plants, engineering and mechanical processing plants. This product can greatly save machining time, improve material utilization, and help improve product quality.


The production methods of seamless steel pipes are different. The main processes are: tube blank, inspection, stripping, inspection, heating, perforation, pickling, grinding, lubrication, air drying, welding head, cold drawing, solution treatment, pickling , pickling passivation, inspection, cold rolling, oil removal, cutting, air drying, internal polishing, external polishing, inspection, marking, and finally finished packaging.
