Electric Fusion Welded Pipe

LSAW welded pipe is for short straight seam submerged arc welded pipe. The production process is simple: using die or forming machine to roll steel plate into pipe shape, then double side submerged arc welding. The advantages: the dimension range is wide. High toughness, good plasticity, good uniformity and compactness are important advantages. So in project construction of long distance oil and gas pipeline, LSAW welded
