Electric Resistance Welding (ERW) pipes have two kinds of welding, induction welding and contact welding. The ERW pipe applied wide hot rolling steel profile as raw material, and went through pre-bending, continuous forming, welding, straightening, cutting and other processes. The pipe has short weld joints, high dimensional accuracy, uniform thickness, and excellent surface and can bear high
Difference between ERW, SSAW, LSAW - Sunny SteelWelded steel pipe (steel 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. Difference in ERW and SAWL Submarine Pipeline and Welding Technology Ambivalence is the watch word for now in China
Differences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

LSAW Welded Steel Pipe Features and Manufacturing 6. Inside weld:This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe. 7. Outside Weld:Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8. Ultrasonic Testing:Outside and inside of the straight seam
LSAW steel pipes vs SSAW steel pipes LSAW steel pipe millOct 05, 2018 · Differently, the SSAW pipe is spiral welded where the LSAW is longitudinally welded. 5) Application Difference:Application of LSAW steel pipes have been widely used in the oil and gas pipelines, especially required large diameter and thick wall pipe with high strength and long-distance.
Mainly as a field gathering pipe and internal high-pressure natural gas pipeline of small-caliber, long-distance pipelines for oil and gas a small number, the vast majority of long-distance pipeline is the use of high-frequency straight seam welded pipe (ERW), spiral submerged arc welded pipe (SSAW), LSAW steel pipe (LSAW) three.
SSAW Pipes, Spiral submerged-arc welding pipes,Spiral Spiral submerged arc welding (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding, and welding them into a spiral. SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes.

Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · An LSAW pipe (submerged arc welding) is manufactured by cutting, bending, and welding steel plates (JCOE process). LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must-go options for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).
Dec 20, 2018 · Seamless pipes have a higher price per ton than ERW pipes, generally 20 to 30% higher, due to their fairly complex production process (more articulated than the manufacturing process of ERW and LSAW pipes) and to due to the fact that the number of seamless pipe manufacturers is rather limited (the market has an oligopolistic nature).
