Straight seam pipe refers to the steel pipe whose weld is longitudinally parallel to the steel pipe. Generally also known as straight seam welded pipe or straight seam steel pipe. Straight seam pipe is made by high frequency welding machine to roll a certain specification of long steel strip and adopt straight seam welding. The specifications of straight seam pipes are expressed by nominal caliber, and can be divided into thin wall straight seam pipes and thick wall straight seam pipes according to wall thickness. According to the shape can be divided into round, square or shaped tube.
| Basic infor mation: | Longitudinally Submerged Arc Welding (LSAW / SAWL) Pipe: the pipe is produced by double-side submerged arc welding and expanded diameter. During the production used pre-welding and then precision welding process, it is stable welding process and high quality weld. |
