DIN 2458 1422mm Longitudinal Submerged Arc Welded Pipes
Outer Diameter : 406.4mm -1422mm (16 ”-56 ”) Water LSAW Steel Pipe
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. According to API standards, LSAW pipe is the only designated type of pipe to be used in large-scale oil and gas transmission pipelines when passing through Class 1 or Class 2 areas such as the alpine zone, submarine, and densely populated urban areas. According to different molding methods, they can be divided into:
UOE welded pipe: single steel plate after the edge of pre-bending, after U molding, O molding, internal welding, welding, mechanical cold expansion and other processes;
JCOE welded pipe: press “J-C-O-E” pre-welding, forming, welding, cold expansion and other processes;
HME welded pipe: It is formed by the “C-C-O” method of mandrel rolling method, and the process of cold expansion after welding.
By carrying out standard Non-Destructive Detections on our LSAW pipes, we ensure that our pipes serve our customers well. Our LSAW steel pipes are ideal pipes for large-scale pipeline water transportation.
