API 5L PSL2 LSAW PIPE is a high performance pipeline pipe with high strength, high toughness and good corrosion resistance, which is widely used in many fields:
The oil and gas industry
1.Long Distance pipelinesAPI 5L PSL2 LSAW PIPE can be used to build long distance oil and gas pipelines both onshore and offshore. Its high strength-to-weight ratio enables it to withstand high internal pressures while maintaining a relatively lightweight construction that is easy to transport and install, and cost effective. For example, the X60Q-class tube is suitable for traversing a variety of terrain, including challenging environments such as frozen soils or earthquake-prone areas, and can efficiently transport large quantities of oil or gas over long distances.
2.Offshore platform riser system
In offshore oil and gas production, the line pipe can be used to connect subsea oil and gas Wells to offshore platform riser system. It not only needs to withstand the pressure of internal oil and gas, but also to withstand the static pressure of external sea water and the dynamic load caused by ocean currents and waves, its corrosion resistance is particularly important in the Marine environment, and can effectively resist the corrosion of sea water.
3.High pressure delivery systems for the petrochemical industryIn refineries and chemical plants, API 5L PSL2 LSAW pipes can be used to transport a wide range of hydrocarbon products and process fluids under high pressure and temperature conditions. The pipeline is resistant to hydrogen induced cracking (HIC) and stress corrosion cracking (SCC), making it suitable for acidic service applications dealing with the presence of hydrogen sulfide.
Energy field
1.Hydrogen transport infrastructureAs the world transitions to clean energy, hydrogen transport infrastructure is becoming increasingly important. The high strength and toughness of API 5L PSL2 LSAW PIPE make it a potential candidate for addressing unique challenges associated with hydrogen transport, such as hydrogen embrittleness.
2.High-pressure power plant boiler pipeIt can be used for high-pressure power plant boiler pipe system, its excellent mechanical properties and corrosion resistance can meet the high pressure, high temperature working environment requirements, to ensure the stable operation of power generation equipment.
Urban infrastructure
1.Urban gas transmission network
It can be used for urban gas transmission to provide stable gas supply for urban residents and industrial users. Its good sealing and corrosion resistance ensure the safety and reliability of gas during transportation.
2.Water piping
The API 5L PSL2 LSAW PIPE is also an ideal choice for large water projects that require high pressure piping. Its durability and corrosion resistance make it suitable for long-term use in water supply systems, ensuring a reliable water supply to urban areas and industrial facilities.
