We can supply all kinds of welded pipes (ERW, LSAW, SSAW), we have a huge range of different welded pipes constantly on stock. ERW (Electric Resistance Welded)ERW Steel Pipe Electric Resistance Welded Steel Pipe is made of hot rolled steel coils/sheets that have been put in a process known as cold roll forming.
More Details Keywords：RHS/ hollow steel tube/ box section steel Anti corrosion Steel Pipe. Anti corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical and electrochemical corrosion reaction of steel pipe.
The ERW (Electrical Resistance Welded) steel pipe is also known as straight seam pipe, it is manufactured by using electric resistance welding. The weld lies inside the tube and is therefore non visible from the outside. The wall thickness of our ERW steel pipe can be customized according to your specific requirement with a thickness deviation 
When the spiral submerged arc welded pipe (SSAW) is a coiled steel pipe, its advancing direction has a forming angle (adjustable) with the centerline of the forming pipe, and the edge is welded while forming. The welding seam is a spiral line. The advantage is that the same specification steel strip can be produced. A variety of diameters of steel pipe, raw material to adapt to a larger range

LSAW steel pipe means Longitudinal Submerged Arc Welded Steel Pipe, which is actually built from hot rolled steel plate or rolls. LSAW steel pipe constantly heads to the big sized welded pipe, which can not be manufactured through electric protection welding strategy.
The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm.The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress.
Senhai especially produces welded steel pipes of large diameter and thick wall thickness in ERW, LSAW and SSAW. Anti corrosion layers can also be done in our factory.

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes . Welded Steel Pipe . LSAW Pipe ; SSAW Pipe (ERW) pipes have two kinds of welding, induction welding and contact welding. The ERW pipe applied wide hot rolling steel profile as raw material, and went through pre bending, continuous forming, welding, straightening, cutting and other processes.

As a welded pipe division of hunan standard steel ,ltd, we mainly produce erw steel pipe, ssaw steel pipe, lsaw steel pipe or other welded pipe products.
ERW PIPE Electric Resistance Welding (ERW) pipes applied wide hot rolling steel proﬁle as raw material, and went through pre bending, continuous forming, welding, straightening, cutting and other processes. The pipe has short weld joints, high dimensional accuracy, uniform thickness, and excellent surface and can bear high pressure.
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small diameter high pressure natural gas pipeline, used for a small number of long distance gas pipeline, the vast majority of long distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
