What is a Double Submerged Arc Weld (DSAW)? -

Oct 31, 2018 · The submerged arc welding process causes metal to coalesce through use of an electrical arc. The electrical arc is transmitted to the workpiece being welded through a consumable electrode. To prevent oxidation from occurring, the electrode and molten base material are protected from oxidation by a flux powder.The difference between straight seam welded pipe and dn700 submerged arc weld steel pipeA narrower blank can be used to produce welded pipes with larger pipe diameters, and a billet with the same width can be used to produce welded pipes with different pipe diameters. But compared with the straight seam pipe of the same length, the weld length is Submerged arc welding pipe, SAW pipes, SAW pipe dn700 submerged arc weld steel pipeSAW 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.

Petrosadid: Longitudinally Welded and Double SAW

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).Longitudinal Submerged Arc Welding (LSAW) Processes dn700 submerged arc weld steel pipeIn 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.Line Pipe - LIBERTY Steel UKFollowing double submerged arc welding, pipe is mechanically expanded and can be produced in a wide range of sizes.
