UOE (Uing and Oing forming) Pipes

UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. read more...
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.

UOE (Uing and Oing forming) Pipes

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.
