LSAW Steel Pipe - Arabian Pipes
APC LSAW Steel Pipe Plant, is located in the Industrial City of Jubail and specializing in the manufacture of Longitudinal Submerged-Arc Welded (LSAW) carbon steel pipe for the Oil and Gas, Petrochemical, Agricultural and Construction Industries. APC is unique, being only the carbon steel pipe manufacturer in the Middle East of both ERW and SAW having a state of the art anti-corrosion coating plant or Introduction to Welded Pipe Manufacturing - The Process In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are: 1.

The alloy content of the coil is often lower than similar grades of steel plate, improving the weldability of the spiral welded pipe. Due to the rolling direction of spiral welded pipe coil is not perpendicular to the pipe axis direction, the crack resistance of the spiral welded pipe materials.ERW/HFW Steel Pipe | Galvanized ERW Steel PipeGalvanized ERW Steel Pipe Advantage. Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipes lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications. Galvanized steel pipes are dipped into a protective zinc coating to protect the pipes from corrosion
