L485 Spiral Submerged Arc Pipe
L485 Spiral welded steel pipe Description
L485 spiral welded pipe is made of X70M/L485M low alloy high-strength steel, which meets the standards of API 5L (American Standard) and GB/T 9711 (National Standard) and belongs to the category of pipeline steel.
Chemical composition: low carbon (C ≤ 0.12%), low sulfur and phosphorus (S ≤ 0.015%, P ≤ 0.025%) as the basis for the addition of niobium (Nb), vanadium (V), titanium (Ti) and other micro-alloying elements, to optimize the grain refining and comprehensive performance.
Mechanical properties
High strength: yield strength ≥ 485MPa, tensile strength ≥ 570MPa, elongation ≥ 21%.
Low-temperature toughness: through the -20 ℃ impact test, adapted to the cold or very cold environment.
Corrosion resistance
Resistant to hydrogen-induced cracking (HIC) and sulphide stress cracking (SSC), suitable for the transport of corrosive-containing media (e.g. seawater, acidic oil and gas).
Process characteristics
Spiral forming + double-sided submerged arc welding: stable weld quality, small heat-affected zone; outer diameter up to Φ3000mm, wall thickness 6-22mm.
