  UOE mill adopts Uing and Oing forming, the formed pipes are welded inside by five internal welding stations with three wires for each weld,and welded outside by four external welding stations with three wires for each weld. According to different customers’ requirements, the welded pipe can be expanded by mechanical or hydrostatic expander to enhance the dimension accuracy, and eliminate the residual stress. ?????????? Specifications: The mill has been equipped with Baldwin Southwork Co,Ltd.’s edge milling, Mannesmann and Mckay Co.,Ltd.’s crimping press, VERSON company’s U-ing press, O-ing press and hydrostatic testing and expanding machine, American Lincoln Company’s modern welding equipment including tab welding, internal welding and external welding.The whole manufacturing process is controlled by computer and PLC. The UOE mill is the best suitable process to meet customers’ requirements by virture of the characteristic of high production efficiency, stable product quality and various accessories for manufacturing and inspection.
