LSAW pipe has large diameter and wall thicknes. It has good resistance to high pressure and resistance to low temperature and strong corrosion characteristics. When constructing high strength and toughness, high quality oil and gas pipeline over long distances, what is required is mostly large caliber straight double submerged arc welding joints. According to the API standard provisions, LSAW pipe is the only designated for tube type when passing through the cold region, submarine, the urban population dense area of 2 kinds, 1 region in the large oil and gas pipeline.
