In accordance with different requirements of the customers, the welded Longitudinal Submerged Arc Welding (LSAW) Processes In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.
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).

SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength The sizes are adjustable & can be tailored to end-user requirements. SSAW Steel Pipe vs. LSAW Steel Pipe - ESC GroupMay 25, 2020 · There are three (3) manufacturing processes high quality steel pipes are being produced:SSAW (Spiral Submerged Arc Welded), LSAW (longitudinal submerged arc welding), and ERW (electric resistance welding). Let us take further on LSAW and ERW pipes. 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
