There are 3 welding types:ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe Difference between ERW Pipes, SSAW Pipes and LSAW Pipes Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same specification can produce SSAW pipes with various diameters. The welding joints can avoid major stress and have better force resistance.
In a single seam SAW steel pipe, the wedding is done with the help of the submerged arc welding process. In this method, a welding arc is submerged in welding flux. A Continues solid filler wire is fed from the outside. The pipe is welding two sides, first is inside, and then welding from the outside. LSAW Steel Pipe, Longitudinally Submerged Arc Welding PipeThe interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process. End facing machine The machine levels the pipe end with rotating cutter heads to ensure that required groove and edge specifications are met. LSAW Steel Pipe, Longitudinally Submerged Arc Welding PipeThe interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process. End facing machine The machine levels the pipe end with rotating cutter heads to ensure that required groove and edge specifications are met.
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing. SSAW Pipes, Spiral submerged-arc welding pipes,Spiral Spiral Submerged-arc Welded Quality Assurance. Spiral welded pipe production by submerged arc method is based on using tandem welding technique for joining inside and outside coil edges, which have been trimmed and beveled by carbide milling for high quality weld structure. SSAW Steel Pipe, SAWH Steel Pipes Supplier In ChinaSSAW steel pipe is made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows the steel pipes manufacturers to produce large-diameter steel pipes suitable for different applications.
Brief overview:SSAW steel pipeSpiral Submerged- Arc Welded Steel Pipe is also known as the SAWH Steel pipe(Submerged-arc Welded Helical pipe Generally used:welded pipes convey fluid, metal structures, pile and so on. Our products are widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, and spiral submerged steel pipe SSAW,SSAW pipe,SSAW steel pipe,Spiral submerged arc SSAW steel pipe,Spiral submerged arc welding steel pipe SSAW steel pipe API5L API 5L, EN-10208, GB9711.1/2, ISO A, B, X42, X46, X52, X56, X60, X65, X70 SSAW steel pipe API5L 1.Uses:Used for the conveyance of water, gas, or pertroleum products and piling pipe Spiral submerged arc welded pipes (SSAW steel pipes As we know, seamless steel pipe always is small dimension,longitudinal submerge arc weld steel pipe is large dimension,but for larger dimension,we should use the method of spiral submerge arc welding instead of longitudinal submerge arc welding.With this method,we can use narrow width steel plates to produce large dimension pipes.The outside diameter is determined by the angle of the de-coiled steel
As we know,seamless steel pipe always is small dimension,longitudinal submerge arc weld steel pipe is large dimension,but for larger dimension,we should use the method of spiral submerge arc welding instead of longitudinal submerge arc welding.With this method,we can use narrow width steel plates to produce large dimension pipes.The outside The difference between ERW, SSAW, LSAW(UOE) Steel pipe 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 Welded Steel Pipes - Zhangzhou Steel PipesZhangzhou Steel Pipes mainly focuses on manufacturing Spiral Submerged Arc Welded (SSAW) steel pipes with two factories in Fujian Province, China. We have the ability to provide various diameters and wall thicknesses of welded steel pipes to accommodate your specific requirements.
Welding Seam Treatment and Process Characteristics of Spiral Pipe. Weld processing:1. If the gap is too large, the proximity effect will be reduced, the eddy current heat will be insufficient, and the weld will have poor intercrystalline joints, resulting in non-fusion or cracking. spiral submerged arc welding ssaw steel pipe, spiral offers 2,546 spiral submerged arc welding ssaw steel pipe products. About 65% of these are Steel Pipes. A wide variety of spiral submerged arc welding ssaw steel pipe options are available to you, such as standard, grade, and application.What is a SSAW pipe? - pipelinedubaiSpiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard.
