The technology of Cold welded pipe mill line adopt the combined roller and panel construction during the production of square/rectangular piped. A ser of roller can cover the majority of the pipe. The sharing rate of the roller is up to 80%. The roller adopting the panel construction contact with the strip in the deformation region but not all, to reduce the contact area, the friction and power consumption of forming roller. At the same time the technology can save about 4% steel strip. According to user needs, the machine can be designed for the production of section steel, square, rectangular and circular tube of multi-functional combination equipment, realizing multipurpose.
