Besides SSAW pipes we can also supply carbon steel ERW pipes, longitudinal welded pipes, seamless steel pipes ERW welded steel pipes longitudinally welded pipes LSAWamp; fittings and stainless steel tubes. Generally, welded steel pipes can be divided into ERW pipes, SSAW pipes and LSAW pipes according to the welding technologies involved to

API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

There are 3 welding types:ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe Comparison of ERW and LSAW Steel Pipes - OilVoiceJan 13, 2020 ERW welded steel pipes longitudinally welded pipes LSAWnbsp; ERW welded steel pipes longitudinally welded pipes LSAW#0183; ERW welded steel pipes longitudinally welded pipes LSAW#32;The Technological Development Process of ERW Steel Pipe. High frequency straight seam welded pipe (ERW) is the hot rolled coil plate formed by the forming machine, using the skin effect and proximity effect of high frequency current to heat and melt the edge of the tube blank, and pressure welding under the action of the squeeze roller To achieve product

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.

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, so the welding LSAW Steel Pipe, EFW Steel Pipe, Welded Steel PipesLSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.

LSAW Steel Pipe, EFW Steel Pipe, Welded Steel Pipes

LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.

Welded steel pipe:ERW Pipe coating

Welded 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. Welded steel pipes-ERW,SSAW,LSAW Hebei Haihao GroupERW (eletrical resistance weld) is a welding method in which pipe is welded without adding filler material.ERW is either high or low frequency.Electric resistance welded steel pipe(ERW steel pipe) is manufactured by cold-forming a sheet of steel plate into a cylindrical shape.ERW has the weld seam on the inside of the pipe.

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.

API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

Welded Pipe manufacturing types There are 3 welding types:ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe in two different manners as listed below.
