High Pressure 9.5mm 40mm Double Submerged Arc Welded Pipe
Longitudinal submerged arc welded pipe (LSAW pipe for short). Longitudinal Submerged Arc Welding (LSAW) is a process of pressing (rolling) steel plate into the billet of die or forming machine, using single plate as raw material. Double-sided submerged arc welding is used to enlarge the diameter. The finished product has complete specifications, good weld toughness, good plasticity, uniformity, compactness, large diameter, thick wall, high pressure, low temperature and corrosion resistance.
LSAW steel pipes widely used in natural gas, LNG and chemical industry. According to API standard, in large gas pipelines, LSAW pipe is the only designated pipeline type in the first and second class areas such as high altitude areas, seabed and densely populated urban areas.
