Tube mills, slitting lines, shearing and edging machines

QINGDAO Haokun Heavy Machinery Technology’s products include ERWmill, SSAW mill, hydrostatic testing machine, end beveling machine and other auxiliary equipment, such as slitting line, longitudinal shear production line and edge milling machine. ERW MILL: ERW production lines specifications: ERW16", ERW20", ERW24". A complete set of ERW25" production lines with horizontal accumulator, high-speed edge milling machine with sawmill, cutting machine and finishing area has already been put in to operation. Another complete set of ERW25" production line to be exported to WBHO in South Africa is already under testing. In addition, the company has mastered all techniques for ERW 630mmx19.1mm with iron grade X80 and has developed JCOE 1420mmx30mm with iron grade X80 welded pipe production line. SSAW mill: from a forming process’s perspective, the products can be divided into external control forming and internal control forming. From a mill production process’s perspective, they can be divided into: accumulator pit stored welding material or backward swing machine unit and forward swing short machine unit in welding tractor style with continuous production capability.
