SSAW Steel Pipe Molding Technology Features

The hot topic of SSAW steel pipe forming technology has always been discussed. As a professional manufacturer and exporter of spiral welded pipes, I would like to express my opinion today.

Carbon steel pipe is a large diameter steel pipe manufacturing process. Since its birth in the United States in 1888, it has continued to promote and develop, process technology is perfect, product quality has also reached a higher level. Its production Wanji more flexible, you can use different width of the steel strip to produce the same diameter of the steel pipe, you can also use the width of the strip to produce different diameter steel pipe. Its production features are mainly reflected in the following aspects:

1. It is possible to continuously produce large-diameter steel pipes with narrower steel strips. The length of the steel pipes can be cut to the required length.
2. It is relatively easy to exchange production specifications.
3. The precision of the steel pipe produced by spiral molding is high, and it can meet the use requirements without sizing and straightening.
4. Continuous production, easy to implement mechanization and automation.
5. The shaper has a simple structure and a small tonnage, so that it occupies a small area, has a small investment, and is quick to construct. However, it is easy to manufacture and easy to operate.
6. Welding is performed at the same time with the forming, and the solder joint is in the obliquely downward position, and the influencing factors of the welding quality are often complicated.
7. The weld length is 1.5-2 times the length of the straight seam steel pipe. When the welding process is poorly controlled, there is a greater chance of welding defects.
8. The production of small steel belts has a great influence on the stability of spiral molding. The position of the welding spot and the gap of the forming seam are in a change, and it is easy to produce defects such as misaligned edges, excessive diameter, and welding deviation.
