Longitudinal submerged arc welded (LSAW) pipe has two type manufacture process.

One is to adopt 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. The mill has the advantages of wide specifications and can produce pipes in any size within its production range.

Another is named as UOE process, The 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 hydraulic expander to improve dimensional accuracy, and eliminate residual stress.
