Low price for 4 Inch Cast Iron Pipe - Longitudinally submerged arc welded LSAW steel pipe – BESTOP

LSAW (Large-surface submerged-arc welded pipe) is produced by using a single medium-thickness plate as a raw material, and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine, adopting a double-sided submerged arc welding method and expanding the diameter. Its product specification range is wide, the toughness, plasticity, uniformity and compactness of the weld seam are good. It has the advantages of large diameter, thick wall thickness, high pressure resistance, low temperature resistance and strong corrosion resistance. When building high-strength, high-toughness, high-quality long-distance oil and gas pipelines, most of the required steel pipes are large-caliber thick-walled LSAW 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.
LSAW pipe is used to convey low-pressure liquid or high-pressure petroleum or natural gas for long distance transport and can also be used widely in structural supports or foundations.
Based on its advantage of high reliability and safety performance, the LSAW pipe is widely used in various pipelines engineering and construction, even under the most severe condition, and also can be used in engineering of chemical industry, electric power, irrigation, construction and piling etc. The advantage of LSAW pipe for oil and gas pipeline: produce more thick wall thickness of pipes, max to 120mm.
Features: Large diameter steel pipes, Thick walls, High-pressure resistance.
