The Use of LSAW steel pipe

LSAW steel pipe has large diameter and wall thickness, resistance to high pressure, 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 steel 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. Test:Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test.Mill Test Certificate:EN 10204/3.1B Third party inspection:SGS, BV, Lloyds etc.
