OVERVIEW OF SSAW/SAWH PIPES:
SSAW (Spiral Submerged-Arc Welded) steel pipes are made of narrower hot rolled plates/coils, which lowers their costs. The diameter of the spiral welded steel pipe can be very large, suitable for transporting large amounts of oil and natural gas.
FEATURES OF SSAW PIPES
SSAW pipes offer a more diverse diameter range compared with ERW pipes and LSAW pipes
Since SSAW pipes are made from narrower hot rolled plates, it lowers the production cost thus brings users additional cost benefits.
SSAW pipes show great performance especially when it comes to stress bearing.
