Longitudinal Submerged Arc Welding (LSAW) Processes In Figure 1 is shown a UOE method for production of longitudinally welded large diameter pipes. Longitudinally edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press subsequently into an O shape using an O-press. Figure 1:Longitudinal seam Submerged Welded (LSAW) pipes with UOE process
Longitudinal steel seam welded pipesWelding of Longitudinal pipe. welding Straight seam pipe generally high-frequency welding, high frequency welding is a kind of induction welding (or pressure contact welding), it does not need to weld filler, weld spatter, welding heat affected zone is narrow, beautiful welding molding, welding, the advantages of good mechanical performance, so in the production of steel by wide application.
Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW). DSAW Pipe is often produced by automatic double-wire double-sided submerged arc welding process.
SSAW Steel Pipe vs. LSAW Steel Pipe - ESC GroupMay 25, 2020 · The two main types of LSAW pipes are:Longitudinal (single or double straight seam weld, DSAW) and Spiral (SSAW, HSAW, or SAWL pipe). The difference between DSAW and LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, while LSAW pipes have a single seam weld on the outer surface, longitudinal or cross sectional.
Seamless vs Welded Steel Pipe Pile Eiffel TradingStraight Seam:Straight seam welded steel pipes are manufactured by adding a welding parallel to the pipe seam. The process is fairly straightforward:Straight seam pipes are formed when a sheet of steel is bent and formed into a pipe shape, then welded longitudinally. Straight seam pipes can be submerged arc welded (SAW) or double-submerged arc welded (DSAW). Spiral Seam:Spiral seam welded pipes

What is a steel pipe? - China piping solution supplier Dec 20, 2019 · Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes. 1. Pipe can be divided according to the basic shape of Longitudinal seam and spiral welded pipe are two:(1) Straight seam welded pipe:simple production technology, high efficiency, low cost, rapid development. Longitudinal more general industrial use.
Which Industries are Straight Seam Steel Pipes Widely Used in?Sep 22, 2020 · Submerged arc longitudinal seam welded pipe is produced by using a single steel plate as raw material, through JCO or UOE forming, submerged arc welding or submerged arc welding combined with other welding processes. Common ones are X70, X80, X120, etc. The diameter of LSAW pipe is 400-1422mm and the wall thickness is 8-44.5mm.
