DIN1626 ASTM A53 S355JRH S355J2H 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 pipe is important and required. On the basis of API 5L standard, it is the only designated welded steel pipe types in areas of cold area, sea and city populated areas.
