LSAW Welded Black Round Steel Pipe for the Fluid Transport
LSAW welded black round carbon steel pipe is widely used in kinds of industry and building areas all over the world.It can be used for Structure, Building, Decoration Machinery and so on.

LSAW(longitudinally Submerged Arc Welding) pipe is produced by using a single medium-thickness plate as a raw material, pressing (rolling) the steel plate into a tube blank in a die or a molding machine, and adopting a double-sided submerged arc welding method to expand 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.
