During the work of the welding pipe, its production process is simple and high in production. The cost is low and develops rapidly during use. The welded pipe can also be welded pipes with different billet production pipes with the same width. However, compared with the same length of the same length, the length of the weld is increased by 30 ~ 100%, and the production speed is lower.
The welded pipe with a large diameter or thicker welded pipe is generally made directly with a steel billet, while the small welded pipe thin -walled welded pipe only needs to be welded directly through the steel band. Then after simple polishing, it is fine.
