42" Inch Diameter St52 Fusion Bond Epoxy Coating LSAW Steel Pipe
LSAW steel pipe has a wide range of finished specifications, good toughness, plasticity, uniformity and compactness of weld, and has the advantages of large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and strong corrosion resistance.In the construction of high strength and high quality long distance oil and gas pipelines, the required steel pipes are mostly large-diameter thick wall straight seam submerged arc welded pipes.According to API standards, in large oil and gas pipeline, when passing through Class 1 and Class 2 areas, such as alpine zone, seabed and urban densely populated area, SSAW pipe is the only designated suitable pipe type.The main bearing parameters are 2ST/T, S is the yield strength, T is the wall thickness.Submerged arc welding has been developed into double - wire submerged arc welding, and multi - wire submerged arc welding, further improve the efficiency.Widely used in steel structure, pile driving, fluid conveying, long - distance pipeline and other places.
In chemical composition, tensile properties, impact energy, and nondestructive testing which strict in PSL1 indicators.2, do PSL1 does not require impact performance, PSL2 all except x80 grade steel, full size 0 ℃ average Akv: longitudinal p j, 41 lateral acuity 27 j.Average grade X80 steel, full size 0 ℃ Akv: longitudinal 101 j, or lateral acuity 68 j.3, line pipe should do water pressure test, and the standards are not allowed to nondestructive generation of hydraulic pressure, which is also the API standard and one big difference between our country standard.
LSAW steel pipe (Longitudinally Submerged Arc Welding (LSAW) is straight seam Submerged Arc Welding steel pipe professional express terms, is based on single thicker plate as raw material, the steel in the mold or molding machine medium-voltage (roll) into the pipe, using double-sided Submerged Arc Welding of pipes and hole enlargement production.Is made of JCOE steel pipe forming, a weld, submerged arc welding process, the specification ranges from 325 mm - 1420 mm.
