We deals in the following products of India, China, Taiwan and Korea Origin:- ERW Steel Pipes
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.
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.

The high-frequency straight seam welded pipe mill is used to level the fixed strip after slitting line and enter it to forming machine, bend to open pipe by roller, melt the strip edges through the High-frequency current, squeeze and weld the pipe to be closed by the squeeze roll. The high-frequency pipe mill is also called ERW pipe mill. Our products technology of full-automatic FFX HFW production line and multifunction 250mm-500mm directly formed square pipeline are among the highest in the industry.
Product: ERW (Electric Resistance Welded ) Steel Pipe, HFW Pipe, ERW Black Pipe Application: Used for Oil/Gas/Water transmission,Machinery Manufacturing
