⑴ Specifications Range
★ Out Diameter: 219mm-720mm( UOE),406 mm-1625.6 mm( JCOE).
★ Wall Thickness: max 65mm.
★ Length: 3.0m-18m.
⑵ UOE SAWL PIPES
The UOE mill features the most sophisticated technology and process, attains high production efficiency, steady product quality and is geared up with complete examination devices.
UOE mill adopts U & O forming, the formed pipes are bonded inside through 5 internal welding stations with three wires, and welded outside through 4 external welding stations with three wires. In accordance with various requirements of the customers, the bonded pipe can be broadened either by mechanical or hydrostatic expander to improve dimensional accuracy, and remove recurring tension.
