Spiral Welded steel pipe is distinguished by the manufacturing process that results in a spiral DSAW seam the length of the pipe to lengths of 155 feet. Interpipe can source and process DSAW pipe to customer specifications. Call one of our sales specialists today to discuss your project needs and suitable steel pipe products for your application!DSAW pipe, Double Submerged arc welded pipe Sunny SteelSpiral Welded steel pipe is distinguished by the manufacturing process that results in a spiral DSAW seam the length of the pipe to lengths of 155 feet. The manufacturing of Double Submerged Arc Welded Pipe involves first forming steel plates into cylindrical shapes.Products, ERW DSAW SMLS pipe Weiler Pipe llc.DSAW Pipe is distinguishable by the spiral DSAW seam that runs the length of the pipe up to 155 feet. AdvantagesThe submerged welding process protects the steel from the contamination of air impurities. The welds also penetrate 100% of the pipe wall, producing a very strong bond.
Double Submerged Arc Welded pipe (DSAW) if cold formed from a single piece of steel plate by rolling or pressing. The longitudinal seam is welded both inside and outside using the submerged arc welding process. Each piece is often cold expanded to meet tight dimensional tolerance.api5l spiral seam submerged arc welded carbon steel pipe Spiral Submerged Arc Welded Steel Pipe, Spiral Submerged offers 1,958 spiral submerged arc welded steel pipe products. About 87% of these are steel pipes, 1% are stainless steel pipes.Types of Oil & Gas PipesSeamless, ERW, LSAW The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface. The difference between LSAW and ERW

Automatic double wire double sided submerged arc welding process welded spiral seam steel pipe.Steel Casing Pipe Straight Seam, Spiral Welded, & Rolled Spiral Welded Steel Casing PipeThis steel casing pipe is a very durable and economical product that gives your project the long lasting reliability you require. The weld seam on spiral weld pipe is in a spiral around the pipe, said to be like a barberpole style This pipe can be manufactured to meet a specific outer diameter, wall thickness Difference between ERW, SSAW, LSAW Sunny SteelSteel 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).
Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line. SSAW pipe (HSAW PipeInterpipe Inc. DSAW & Spiral Weld PipeDSAW pipe can be specified in very large diameter and to exact inside or outside dimensions. Spiral Welded steel pipe is distinguished by the manufacturing process that results in a spiral DSAW seam the length of the pipe to lengths of 155 feet. Interpipe can source and process DSAW pipe api5l spiral seam submerged arc welded carbon steel pipe DSAW carbon steel pipe is easily distinguishable due to its prominent and consistent ID and OD weld seam. Common DSAW specs include; API5l, A252, and A139. Spiral Weld. The most easily distinguishable manufacturing method for carbon steel pipe is spiral weld.[plate]China API5l X70 SSAW Spiral Welded Steel Pipe factory and
The spiralweld manufacturing process is one of the most cost effective ways to produce steel pipe. Spiralweld pipe is manufactured from steel coil and typically utilizes a helical double submerged arc weld (DSAW). The mill setup offers avarying degree of flexibility, allowing for production of a wide range of pipe diameters and wall thicknesses.Welded Steel Pipe American Piping ProductsWelded Pipe American Piping distributes an extensive selection of welded pipe, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe along with their respective flanges and fittings. We also carry A139 Grade B, A252 Grades 2 & 3 spiral weld pipe, and A691 chrome moly pipe.Spiral Submerged Arc Welded Pipes, Spiral Seam Steel Pipe Spiral Submerged Arc Welded Pipes, Spiral Seam Steel Pipe, Spiral Steel Pipe Manufacturer, Supplier in China.

Williamson SpirALL® Magnetic Flux Leakage (SMFL)Compact magnetizer design to create a spiral or transverse magnetic field that provides 100% coverage of the pipe wall Detects axial planar or crack like defects not detected by axial MFL Able to distinguish attributes of long seam type electric resistance welded (ERW), electric fusion welded (EFW), double submerged arc welded (DSAW), lap
Straight seam steel pipe is the production of steel plate, and spiral welded pipe is hot rolled coil production. The rolling process of the hot strip mill has a series of advantages, and has the ability to obtain the metallurgical technology of producing high quality pipeline steel. For example, a water cooling system is provided on the output 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.Differences Between SAW and ERW Pipe Winsteel GroupThe 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. And the weld seam of the SAW pipe is not flat. SSAW pipe weld seam. SAW pipe weld seam. LSAWweld seam. You will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate.
