Surface:Black Painting/Oil Painting/Anti-Rust oil/Anti-Corrosive Coating
Process: LSAW – UO(UOE),RB(RBE),JCO(JCOE,COE) DSAW -Double Submerged arc welded
Usage: Used for low pressure liquid delivery, such as water, gas, and oil.
The UOE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipments. UOE mill adopts U & O forming, the formed pipes are welded inside through five internal welding stations with three wires, and welded outside through four external welding stations with three wires. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expander to improve dimensional accuracy, and eliminate residual stress.
JCOE LSAW steel pipe:
Specifications:
Outside Diameter:Φ406mm- 1626mm (16" - 64" )
Wall Thickness:6.0- 75mm (1/4" - 3" )
Quality Standards:API,DNV,ISO,DEP,EN,ASTM,DIN,BS,JIS,GB,CSA
