Welding Steel Pipe

Welding pipe also called welded steel pipe is made of steel plate or steel strip through crimp forming thus welding. The length is 6 meters. Welding pipe production technology is simple, high production efficiency, variety specifications, less equipments investment while the strength is generally lower than seamless pipe.

With rapid development of high quality strip steel rolling production and improvement of welding and testing technology, welded pipe is gradually taking the place of seamless steel pipe in the most field. Due to increasing welded quality, the specifications of welded steel pipe are variety. Small diameter welding pipe uses straight seam welding, large diameter welded pipe uses spiral welding.

How is the Production Process of Welding Pipe?
The production technology of straight seam welded steel pipe is simple, high production efficiency, low cost and rapid development. The strength of spiral welding pipe is generally higher than straight seam welded steel pipe. Compared with the same length of straight seam pipe, welding seam increases by 30-100% and the production speed is much lower.

Larger diameter or thicker welding pipe is usually made by steel billet directly. While small or thin wall welding pipe only need to weld steel strip directly. Then through simple polishing and wire drawing, the welding pipe is fine.
