SSAW Pipe (HSAW Pipe) Manufacturing Process. SSAW Pipe (Spiral Submerged Arc-Welding Pipe), also called HSAW pipe (Helical SAW), welding line shape like a helix. It is using the same welding technology of Submerged Arc-Welding with LSAW pipe. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.
Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe. Owing to the flux layer, there is no instant heat loss and it gets concentrated near the weld.
Spiral Submerged-Arc Welding 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.
Spiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force better, the disadvantage is the poor geometry of the weld length compared to the long straight seam pipe, prone to cracking, porosity, slag, welding efw ssaw lsaw spiral welded steel pipeDifferences Between SAW and ERW Pipe Winsteel GroupYou will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate. And the tolerance of weld seam height is specified in specifications. If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish.
Electric Fusion Welding(EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.Images of EFW SSAW lsaw Spiral Welded Steel Pipe hbcytubeDn1000 erw lsaw ssaw spiral steel pipe China Manufacturertecnos-sa.chWelded Pipes - ProjectmaterialscnspipesChina SSAW Carbon Steel Spiral Welded Pipe Suppliers efw ssaw lsaw spiral welded steel pipemetalsteelpipeANSI B36.10 SSAW / LSAW/ ERW/ EFW Welded Steel Pipe For efw ssaw lsaw spiral welded steel pipepiyushsteel-pipesAPI 5L EFW / ERW Carbon Steel Pipe, API 5L Lsaw /Hsaw efw ssaw lsaw spiral welded steel pipe imagesPeople also askWhat is a spiral welded pipe?What is a spiral welded pipe?Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time.

Used for oil/gas/water Transmission,Engineering/Offshore projects. LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.
6. Inside weld This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe. 7. Outside Weld Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8.Petrosadid Electric Resistance/ Fusion Welded (ERW and EFW)ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is especially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
Spiral Submerged-arc Welded steel pipe technological process The SSAW pipe is widely used in long distance pipeline project for transmission of oil, natural gas, water as well as coal gas, and also is used in all kinds of engineering, such as chemical industry, electric power, irrigation, construction and piling etc.Seamless steel pipe|carbon steel pipe|Stainless steel pipe efw ssaw lsaw spiral welded steel pipeAs a professional manufacturerDMH United Steel Industry offer you the best steel pipes,such as Carbon pipes,seamless steel pipe,stainless steel pipe,welded pipe,ERW,SSAW,LSAW and pipe
