Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.

We absorbed the international advanced technology of tube making, like FFX and cage forming flexible formation technology etc, which apply CAD system to deformation process of welding pipe, which analysis and research the distortion craft of high grade steel pipe, also coordinated with high-performance welding machine to solve better the forming and welding defects that provide the high grade & high value-added welded pipe products for users.
In the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure. Roller sleeves are filled between roller pieces. The pieces structure is used for rollers. In the deformation region, rollers contact strip steel partially not fully, reducing the contact area and reducing the friction between strip steel and rollers accordingly.
