EFW pipe vs SSAW pipe ERW - Electric Resistance Welded. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes.
SSAW steel pipe, spiral submerged arc welded pipe is coiled its forward direction and shaping of the center line of the pipe forming angle (adjustable), side shaping welding edge, the weld into spiral line, the advantage of the same specifications can produce a variety of diameter specifications of steel, raw adaptation range is larger, weld Electric Resistance Welded - an overview ScienceDirect Spiral submerged-arc welded (SSAW) pipes are used for larger-diameter pipelines of 400 mm and above, but the pipe diameter is dependent on the angle of coil and thickness of the sheet used. Manufacture is by using a hot roll of steel that is unwound using a series of rollers.
Jul 26, 2018 · The SSAW pipe diameter range is from 20 inch (406 mm) to 100 inch (2540 mm).The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress. LSAW Steel Pipe VS. SSAW Steel PipeLSAW and SSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally. In the SSAW type, steel coils are welded spirally, like a helix, so that
Production Process. 1.Raw materials are strip steel coils, welding wires, and fluxes. Strict physical and chemical tests are required before investment. 2.Butt joint of strip steel head and tail, adopt single wire or double wire submerged arc welding, after coiling into steel pipe, adopt automatic submerged arc welding repair welding. Products Taurus Pipeline SolutionLSAW 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. Pipe O.D:406.41422.4mm16-56in
DSAW PIPE:Double Submerged Arc Welded (DSAW) is manufactured by first forming steel plates into cylindrical shapes. The edges of the rolled plate are formed to produce v-shaped grooves on the interior and exterior surfaces at the seam. The pipe seam is then welded by an arc welder in a single pass on the interior and exterior surfaces. SPIRAL PIPE CASING - Alberdo IndustriesSpiral Submerged Arc Welded or SSAW pipes are highly noticeable because of their helical welding seam. Spiral steel pipe casing, which is also called pipe piles and bored pipe casing, is normally used in the foundation of structures that have soft soil. These pipes can also be used in water lines that require big diameter and lengths.

SSAW pipes are mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.
Submerged arc welding spiral steel pipe Feb 21, 2021 The production process of submerged arc welding spiral steel pipe:It is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process with strip steel coil as raw material, often extruded and Submerged arc welding spiral steel pipe - Knowledge The production process of submerged arc welding spiral steel pipe:It is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process with strip steel coil as raw material, often extruded and formed at temperature.
LSAW 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. q345 seam submerged arc welded pipe for hydropower Longitudinally Submerged Arc Welded Steel pipes, LSAW q345 seam submerged arc welded pipe for hydropower plantMainly 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
Spiral Submerged Arc Welded pipe, is a low-carbon structural steel or low-alloy structural steel strip according to a certain degree of helix angle (called forming angle) into a tube blank, and then by pipe seam welded together, It China Transport Oil & Gas Helical Submereged Arc Welded spiral piling ssaw helical submerged arcSteel Pipes, Pipes SSAW Steel Pipe Manufacturing Process - Permanent Steel Spiral steel pipe (SSAW steel pipe) is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit.
