Pipe is welded on one of three welding stands using a three-wire inside pass followed by a two-wire outside pass. The deposits overlap to provide a full penetration weld. The welding process is computer controlled and weld alignment is automatically adjusted by a laser tracking system.

Difference between erw and saw steel pipe, Sunny Steel Difference between erw and saw steel pipe is also known as soft steel, the carbon content is from 0.10 to .30% and easily accepted by various processing such as forging, welding and cutting, commonly used in the manufacturing chain, rivets, bolts, shafts, etc.
Dec 19, 2018 · As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW pipe means Electric Resistance Welded pipe. Second, Different Weld Seam Between SAW and ERW Pipe . The surface quality is very important for pipes. Though both SAW and ERW pipes all have a weld seam. But for weld seam of ERW pipe is flat.

Large diameter Spiral-Welded SSAW/SAWH tubular steel Spiral Submerged Arc Welded Pipe Pile (SSAW Steel Pipe) SSAW can be manufactured in large lengths and diameters. Spiral welded tubular pipes are produced from internally and externally welded steel coils. Piling pipes can be welded with pipe shoes
Welded pipe vent pipe weld not only affect the density, resulting in leaking pipes, and corrosion-induced point will become a serious decrease weld strength and toughness. Produce weld porosity of factors:the flux of water, dirt, oxide and iron, welding components and cover thickness, the surface quality of steel and steel side plate

What is The Differences Between LSAW Pipe and SSAW PipeThe 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.
