Jan 13, 2020 · It can be used as water gas pipe or threaded pipe, which is relatively thick. 2. The line pipe is also a wire tube, which is relatively thin. It is indicated by "T" and can only be used as a pipe. 3. The ERW pipe is a "high-frequency resistance welded steel pipe", which is different from the ordinary welding pipe welding process. Difference Between ERW, SSAW, LSAW - Carbon Steel Pipe Seamless steel pipes are mainly used in oil pipeline and gas pipeline, but seldom used in oil pipelines with long-distance. Most long distance pipeline applied ERW pipes, SSAW pipes and LSAW pipes. Here are comparisons of technological features and performance of these pipes. 1. Electric Resistance Welding Pipes
Winsteel Group as a professional lsaw pipe welding factory, we have got API 5L & ISO certificate for more than decade years. Welded Pipes made by lsaw pipe mill are using steel plate as raw material. Lets see lsaw pipe manufacturing process, first, plate is rolled in the circular section with the help of plate bending machine. LSAW Steel PipeProduct:LSAW pipe,Longitudinally Submerged Arc Welding Pipe Application:Used for oil/gas/water Transmission,Engineering/Offshore projects. LSAW steel pipe manufacturers and suppliers XinYue GroupLongitudinal Submerged-Arc Welded Steel Pipe Process:LSAW UO(UOE)RB(RBE)JCO(JCOE,COE) DSAW -Double Submerged arc welded Usage:Used for low pressure liquid delivery, such as water, gas, and oil. Standard:API 5L, API 5CT, ASTM 53, EN10217, DIN 2458. IS 3589, GB/T3091, GB/T9711 Certif
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. Longitudinally Submerged Arc Welded Steel pipes, LSAW After cold expansion for lsaw steel pipe, steel tube and pipe end diameter will increase by about one percent difference in diameter of the diameter, roundness, and the pipe ends are greatly improved, also have greatly improved the straightness of the steel pipe, steel pipea length of about 0.5% reduction in wall thickness decreases by about 0.8%. Petrosadid:Longitudinally Welded and Double SAWWelded 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).

Next: Jetsun is a professional supplier of steel material in China.We provide common & customized steel pipes, pipe fitting and steel panels which are widely used for industries of petroleum, chemical engineering,nuclear power, paper making, marine The difference between ERW, SSAW and LSAW - rainbow-steelIn the construction of long-distance oil and gas pipelines with high strength, toughness and quality, most of the steel pipes are LSAW with large diameter and thick wall. According to API standards, in large oil and gas pipelines, when passing through 1 or 2 areas (such as high mountains, seabed and densely populated urban areas), longitudinal
Straight seam high-frequency welded pipe (ERW) is divided into two types of induction welding and contact welding according to different welding methods. Hot-rolled wide-gauge steel coil is used as raw material, after pre-bending, continuous forming, welding, heat treatment, sizing, straightening, Cutting and other processes, compared with spiral welded pipe with a short weld, high dimensional What is The Differences Between LSAW Pipe and SSAW PipeLSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It 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. What is a LSAW steel pipe? ASTM A234 butt weld pipe LSAW pipe is used to convey low pressure liquid meida or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation. The advantage for LSAW type is they could produce more thick wall thickness of pipes, maximum to 120mm. Specifications of LSAW steel pipes:Size:Outer Diameter:219mm-1820mm
Feb 27, 2017 · SSAW 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. These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction. Difference between ERW, SSAW, LSAW - Sunny SteelDifference 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).
