Manufacturing Process Of LSAW Pipe

UOE pipe is a type of longitudinally welded steel pipe produced using the UOE method, which involves crimping, U-pressing, O-pressing, and expanding.

UOE is more suitable for the production of single-size, high-volume products

Specifications
UOE pipes size range:
Outside Diameter： Φ508mm- 1118mm (20"- 44")
Wall Thickness： 6.0mm-30.0mm（1/4"-1"）
Length： 9m-12.3m (30'- 40')
Quality Standards： API、DNV、ISO、DEP、EN、ASTM、DIN、BS、GB、CSA
Grades： API 5L A-X90,GB/T9711 L190-L625

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 Pipe refers to a type of longitudinally submerged arc-welded (LSAW) steel pipe that is produced using the JCOE forming process.

The mill adopts continuous axis contorting J-C-O(J-ing, C-ing and O-ing)process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress.
