Product Description

Easy To Operate Cold Roll Forming Carbon Steel Square Tube Mill



The high-frequency pipe production line is specialized equipment to produce high frequency straight seam welded pipes for structuralpipe and industrial pipe with 35mm×35mm -70mm×70mm and wall thickness of 1.5mm-3.5mm.Square pipe making machine can form steel strip into round pipe, and then turn it into square or rectangular shape. It consists of equipment from raw material uncoiling to pipe cutting off and collecting. This pipe making progress is automatic so it is of large production capacity.
