API 5L 360NB X42 UOE Steel Pipe With Electric Fusion Welding Low Carbon Steel

EFW steel pipe

EFW is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated, so the seam is less visible.

DSAW Double Submerged Arc Welded Pipe

DSAW or Double Submerged Arc Welded Pipe derives its name from the welding process wherein the welding arc is submerged in flux while the welding takes place

. Both inside and outside welds are required and are usually accomplished in separate processes, hence the word "double." These separate welds consume a portion of the other, resulting in a single high quality weld nugget.

DSAW Pipe is normally produced in double random lengths with square ends or beveled for welding.

DSAW Pipe is used in high-pressure gas and oil transmission lines (both onshore and offshore), structural members and Pipe piles.
