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). Difference between ERW, SSAW, LSAW - Sunny SteelSpiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force better, the disadvantage is the poor geometry of the weld ERW Steel Pipe, A53 ERW Pipe - Seamless Steel PipeERW (Electric Resistance Welded ) Steel Pipe Standard. for erw pipe ASTM A53 B, ASTM A178, ASTM A252 GR.2 API 5L X42/46/52/56/60/70 ASTM A500, ASTM A513 EN 10204/10217 S235JR,S275JR, S355,S355JR,S355J2H
Hot sale various high quality ERW steel pipe, JIS G3456, Carbon ERW steel pipe, welded bare erw steel pipe from China leading manufacturer. Our products are efficient, cost effective and deliver more benefits. Welcome to choose us! ERW Steel PipeB) Good mechanical properties.As the ERW steel pipe with easy control of rolling, with the welding technology and on-line heat treatment technology, the performance of the weld can be controlled, so straight seam welded steel pipe elongation than seamless steel pipe 8% -10% higher, which Is because the straight seam electric-welded pipe carbon content of less than 12% lower than the seamless tube. ERW Tube Mill, Direct Forming to Square Pipe Mill, Spiral ERW 660 Tube Mill. ERW660 tube mill/pipe mill/welded pipe production/pipe making machine is used to produce steel pipes of 406mm-660mm in OD and 8.0mm-20.0mm in wall thickness, as well as corresponding square and rectangular pipe.
SPT Technology is focus on all the steel pipe machinery solution including the ERW tube mill and their pipe finishing equipment straightener , beveling, hydro-tester, NDT , heat treatment equipment, coating line, bundling and packing equipment. And seamless tube mill, spiral welded pipe mill, LASW, HASW- We also can provide the newest technical case from China. How is the Welded Steel Pipe Made?ERW steel pipe:high-frequency straight-slit electric resistance welded pipe, which adopts hot-rolled wide-rolled material as material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting and other processes, compared with spiral, it has short weld seam, standard The precision is high, the wall Large diameter erw spiral welded steel pipe - Weld Steel PipesSpiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe.

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. The difference between ERW steel pipe and spiral steel Jun 03, 2018 · The ERW welded pipe has a simple production process, high production efficiency, low cost, and rapid development. Spiral 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.
Manufacturer of welded pipes and tubes, include erw steel pipe, hfw steel pipe, lsaw steel pipe, sawh steel pipe,ssaw steel pipe,etc. 0086-731-88739521 [email protected] English What is EFW steel pipe - pipelinedubaiWhat is EFW steel pipe? EFW steel pipe (Electric Fusion Welding steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld.EFW steel pipe is formed by rolling plate and welding the seam. What is a Welded Steel Pipe? About Welded or ERW Steel 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. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.
Interpipe can provide you with Electric Resistance Welded (ERW) Pipe suitable for your project needs. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge. Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet.
