API 5L steel line pipe is for oil and gas industries pipelines, developed for different working environments. Difference Between Spiral Welded Pipe and Straight Welded Nov 11, 2019 · The main difference between the two welded pipes of spiral welded pipe and straight welded pipe is the difference in welding form. Spiral welded pipe is a low carbon carbon structural steel or a low alloy structural steel strip rolled into a tube blank with a certain helix angle (also called forming angle), and then welded and made into a pipe joint, which can use a narrow strip steel
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. Difference between ERW Pipes, SSAW Pipes and LSAW 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. ERW, SSAW, LSAW Welded Steel PipeERW steel pipe:high-frequency straight seam resistance welded pipe, using hot-rolled wide coil as the material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, blocking and other processes, it has a shorter weld seam than the spiral, standard High precision, uniform wall thickness, good surface quality, and high-end benefits under pressure, but the
SSAW steel pipe is a coiled steel pipe made from strip coils as the raw material, which is often warm extruded and welded by an automatic double wire double-sided submerged arc welding process. The strength of the ssaw steel pipe is generally higher than that of the lsaw steel pipe. LSAW Steel Pipe, DSAW Steel Pipe, Welded Steel PipeTypes Standard SY/T5040-2000 SY/T5037-2000 SY/T9711.1-1977 ASTM A252 AWWA C200-97 API 5L PSL1 Tube end OD deviation LSAW Steel Pipe-HELICAL WELDED STEEL PIPE|Longitudinal Tianjin Xinyue Steel Group main prodects:ASTM A252 Spiral Steel Pipe,ASTM A106 GR B Carbon Steel Pipe,API 5L GR B Seamless Steel Pipe,ASTM A53 GR B Black Steel Pipe,HELICAL WELDED STEEL PIPE,Longitudinal Submerged Arc Welded steel Pipe.
Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut 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. Furthermore, the mechanical properties of the pipe base metal and weld metal were tested, and the results were in accordance Spiral Welded Pipe - Nucor SkylineSpiralweld pipe, like ERW, is also manufactured from steel coil. The difference is the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix. This allows for a lot more variation in diameter and thickness than ERW pipe. Spiral Welded Pipe:Specification Sheet - Carbon Steel PipeBelow is the specification range for sprial welded pipe supplying. The outer diameter production ranges from 219.1mm to 3500mm. The wall thickness production ranges from 6mm to 25mm. PRIME STEEL PIPE is able to supply the spiral steel pipe/ssaw steel pipe within this range with the variable international standards.
Seam welded pipe production technology is simple with high production efficiency, low cost and rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, and can adopt a narrow billet to produce larger diameter welded pipes, and it can also use the billet with the same width to produce the different pipe diameter welded pipe. Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface. Welded Steel Pipes Supplier Philippines Welded Pipe Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, sot he welding seam is in a spiral line.
Transverse crack in the weld of thick-walled lsaw steel pipe D36, D36-Z35 and S355 structural steel plates with thickness of 20~50mm are used respectively to produce marine experience exchanges through the JCOE forming method. The lsaw steel pipe of the 54.HAN GUAN welded pipe platform are 508~1372mm in diameter. lsaw steel pipes vs ssaw steel pipes lsaw steel pipe millDifferently, the SSAW pipe is spiral welded where the LSAW is longitudinally welded. 5) Different Application:LSAW steel pipes have been widely applied in the oil and gas pipelines, especially required large diameter and thick wall pipe with high strength and long-distance. Meanwhile in construction of a structure that needs tough strength ssaw_erw_lsaw-Cangzhou Spiral Steel Pipe (Group) Co., Ltd.Cangzhou Steel Pipe Group (CSPG) Co., Ltd. is a large-sized, key metallurgic enterprise of Hebei Province in North China, whose history dates back to 1994. CSPG currently em/paces six member companies with products varying from SSAW, LSAW, ERW, seamless steel pipes to 3PE pipes, galvanized pipes, casing pipes, etc.
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
