API 5L L360 Pipeline Steel Plate And API 5L X52
API 5L L360 pipe is a low carbon steel pipe, which plays an important role in many fields such as oil and natural gas. API 5L L360 high strength pipe has a minimum yield strength of 52ksi. It follows the API SPEC 5L standard of the American Petroleum Institute, covers two major categories of seamless pipes and welded pipes, and provides clear guidelines for the use of API 5L L360 pipelines in different application scenarios.
API 5L L360 has two product grade specifications, namely PSL1 and PSL2. The chemical composition of PSL2 is relatively rich, including carbon, manganese, phosphorus, sulfur, silicon, vanadium, niobium and titanium. The composition of API 5L X52 PSL1 is relatively simple, mainly manganese, phosphorus, sulfur and trace amounts of vanadium, niobium and titanium.
API 5L L360NS Nace Pipe is designed for high resistance when conveying corrosive media and toxic gases. For possible reduction problems, protective layers such as FPE, galvanizing or 3LPE coating can be used to enhance its corrosion resistance, extend the service life of the pipeline, and ensure the safe and stable transmission of the medium during long-distance transportation.
GNEE provides API 5l X52 LSAW pipes with an outer diameter ranging from 2 inches to 24 inches and a maximum wall thickness of 250 mm. Such a wide range of sizes, combined with different wall thickness and outer diameter combinations, has spawned a rich and diverse product schedule, ranging from sch10 to XXS, which can accurately match the most suitable pipe according to specific pressure, flow and other requirements.
