PRODUCT DETAILS
Description
Longitudinally Submerged Arc Welding Pipe is subdivided into UOE, RBE, JCOE steel pipe according to its different forming methods. Longitudinal high-frequency welded steel pipe has the characteristics of relatively simple process and fast continuous production, and has wide use in civil construction,petrochemical, light industry and other sectors. Mostly used to transport low pressure fluids or made into various engineering components and light industrial products.
UOE LSAW PIPES
| UOE LSAWPIPES | The UOE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipments. |
| Prodution Line | 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. |
| Specifications | Outside Diameter: φ508mm-1118mm(20"-44") Wall Thickness: 6.0-25.4m m (1/4"-1") Quality Standards: API、DNV、ISO、DEP、EN、ASTM、DIN、BS、JIS、GB、CSA Length: 9-12.3m (30' - 40') Grades: API 5L A-X90,GB/T9711 L190-L625 |
JCOE LSAW PIPES（PRESS BENDING）
| Prodution Line | This is large diameter longitudinal submerged arc welded (LSAW) pipe production line in China. The mi ll adopts progressive bending process, featuring evenly distributed forming stress, high uniformity of dimension, infinite sizes variation& wide product range, and high flexibility, etc. |
| 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 Length: 3-12.5m (10'-41') Grades: API5L A-X100,GB/T9711 L190-L690 |
JCOE LSAW PIPES（ROLL BENDING）
| Production Line | This is the first large diameter longitudinal submerged ar c welded (LSAW) pipe production line in China. The mi ll adopts continuous axis contorting J-C-O form ing process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress. The mi ll has the advantages of wide specifications and can produce pipes in any size within its production range. |
| Specifications | Outside Diameter: φ406mm-1829mm(16"-72" ) Wall Thickness: 6.0-30mm (1/4"-11/6") Quality Standards: API、DNV、ISO、DEP、EN、ASTM、DIN、BS、JIS、GB、CSA Length: 3-12.2m (10'-40') Grades: API5L A-X80,GB/T9711 L190-L555 |
