Product information of welded steel pipe

Welded steel pipe is a seamed steel pipe. The production process is to bend the pipe blank (steel plate and steel strip) into a tube of the required cross-sectional shape and size by various forming methods, and then weld the weld by different welding methods. The process of obtaining a steel pipe. Compared with seamless steel pipes, welded pipes have the characteristics of high product precision,especially wall thickness accuracy, simple main equipment, small footprint, continuous operation in production, flexible production, and wide product range of the unit.

From the production process,welded pipes are further divided into: Spiral Submerged Arc Welding; LSAW (Longitudinally Submerged Arc Welding); ERW (Electric Resistance Welding).
