Difference between ERW, HFW, SAW, EFW pipe & seamless

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). LSAW Steel Pipe - Gnee steelLSAW Pipe 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.

LSAW Steel Pipe, DSAW Steel Pipe - Seamless Steel Pipe

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. LSAW Steel Pipes Manufacturers, Factory Suppliers,Buy API Metline is a specialized manufacturer and factory supplier of Longitudinal Submerged-Arc Welded (LSAW) carbon steel pipes for the Oil and Gas, Petrochemical, Agricultural and Construction Industries. We can supply high quality LSAW pipes with various standards, including but not limited to API 5L GR A, GR B, X42, X46, X56, X60, X65, X70. Seamless Steel Pipe vs. Welded Pipe:What Are the Mar 16, 2021 · Examples of ASTM or API 5L welded steel pipes include SSAW pipe, ERW steel pipe, and LSAW pipe. Many people confuse the ERW pipe with seamless steel because it does not use fusion metals, the weld seam is not always visible, and you cannot feel it. On the contrary, a Double Submerged Arc Weld (DSAW) leaves evident traces of weld beads, which

Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. Longitudinally Submerged Arc Welded Steel pipes (LSAW) In High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve Welded Steel Pipes - Zhangzhou Steel PipesBoth SSAW and LSAW pipes are large-diameter steel pipes. LSAW steel pipes welding line is straight while the SSAW welding line is spiral. LSAW steel pipes length range from 3 meters to 15 meters long. The normal maximum length of the LSAW steel pipe is only about 15 meters long. Welded steel pipe:Welded steel pipeWelded steel pipe Sunny Steel produce an extensive selection of welded pipe including Electronic Resistance Welded (ERW), Electronic Fusion Welded (EFW), and Double Submerged Arc Welded (DSAW) carbon steel pipe along with their respective flanges and fittings.
