High Pressure Resistance 12m 24 Inch LSAW Steel Pipe

API 5L GR X52 X65 X70 X80 24 inch LSAW Steel Pipe For Oil&Gas Definition

　　LSAW steel pipe is a cylindrical shape in which a hot rolled coil is formed by a forming machine and deforms the coil into a smooth shape, and is welded by using a skin effect and a proximity effect of a high-frequency current or an arc burning under a layer of the solder. The edge is heated and melted, and it is fused under a certain squeezing force and finally cooled to form. The edge of the tube, which is melted by a high-frequency current, is called a high-frequency straight welded tube (ERW), and the arc melting is called a longitudinal welded pipe (LSAW).

LSAW Steel Pipe Manufacturing Process

　　LSAW steel 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.

Diameters range and performances of LSAW steel pipe

　　The LSAW steel pipe diameter range is larger than ERW, normally from 16 inch to 60 inch, 406mm to 1500mm. Good performances on high pressure resistance, and low-temperature corrosion resistance.

Applications of LSAW steel pipe

　　LSAW steel pipe has been widely applied in the oil and gas pipelines, specially required large diameter and thick wall pipe with high strength and long distance. Meanwhile in construction of structure that need tough strength, water treatment, thermal industry, bridge building, etc. According API specifications, the LSAW steel pipe is specially designated in large scaled oil and gas transportation, in the cases that pipelines across the city, sea, and the urban area.
