LSAW Steel Pipe, Longitudinal Submerged Arc Welded - Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service, high performance and tight tolerances. LSAW pipe are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects. ASME B36.10 LSAW Pipe,API 5L X42 PSL1 28 Inch SCH XS 12M
LSAW Pipe 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.
Longitudinal Submerged Arc Welding LSAW Steel Pipes LSAW Steel Pipe s (longitudinal submerged arc welding) are usually the most economical solution when high wall thickness is required due to high internal or external pressure. LSAW Steel Pipe s are larger in diameter than ERW (resistance welding), typically from 16 inches (406 mm) to 60 inches (1500 mm).
Longitudinaly Submerged Arc Welded PipesLongitudinal Submerged Arc Welded Steel Pipes (LSAW) for oil&gas industry but also for other industries; pressure applications, structural applications, water transportation. With a nominal capacity of 50 kto/year and a wide dimensional feasibility, the line is addressing several applications such as:welded steel pipes for use in pipeline
Steel can be offered in other grades if required (e.g. ASTM grades, API grades, and more). Please contact us directly for further details. ELECTRIC RESISTANCE WELDED STEEL PIPE (ERW)
longitudinal seam submerged arc welded steel pipe - The longitudinal seam submerged arc welded steel pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements.
longitudinal submerged arc welded pipes, longitudinal 84 longitudinal submerged arc welded pipes products are offered for sale by suppliers on , of which steel pipes accounts for 3%. A wide variety of longitudinal submerged arc welded pipes options are available to you, such as 10#-45#, a53-a369, and q195-q345.
Longitudinal submerged arc welded (LSAW) pipes manufacture process is bending and welding wide steel plates to pipes from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter "J", "C", "O" or "U" shape, then expansion) forming processes.
