The high-frequency pipe production line is specialized equipment to produce high frequency straight seam welded pipes for structuralpipe and industrial pipe with 70mm×70mm -170mm×170mm and wall thickness of 2.0mm-6.0mm.
Compare with round into square&rectangle forming way,this way is better for the shape at the edge of cross section,comparatively, semi-diameter of inner arc is Small, and the brim is flat, outlook is regular.
It is directly roll the steel strip and bend it to square & rectangular shape, then weld it to finish the formation.
