LSAW Steel Pipe For Petroleum Pipeline And Natural Gas LSAW Steel Pipe

Spiral submerged arc welding can use narrow steel strip to produce large diameter welded pipes, and can also produce welded pipes with different wall thicknesses according to the demand, which meets the diversified engineering construction needs. Longitudinal submerged arc welding plays an important role in pipeline construction with high pressure and high strength requirements by pre-bending the edge of steel plate and then rolling it into a tubular welding, which has high dimensional accuracy of steel pipe and good surface quality of internal and external walls.
