Typical Application Scenarios of Steel Pipes

2025-03-24


Energy Arteries—Oil and Gas Transmission Systems
Long-distance pipelines: X80 grade steel pipes, under 5-10 MPa pressure, can transport up to 40 billion cubic meters of gas annually, equivalent to replacing 40 million truck shipments.
Deep-sea engineering: Using double-layer epoxy powder-coated steel pipes, it can withstand high pressure and seawater corrosion at depths of 300 meters, ensuring the development of offshore oil and gas fields.
Urban Lifelines—Municipal Pipe Network Systems
Smart water management: Steel-plastic composite pipes with PE lining combine the strength of steel pipes with the hygiene of plastic pipes, with a service life of 50 years and a leakage rate of less than 3%.
Comprehensive pipe galleries: Pre-fabricated assembled steel pipe gallery frames, on-site installation efficiency increased by 70%, realizing the sharing of multiple pipelines such as electricity, communication, and water supply.
Industrial Backbone—High-end Manufacturing Field
Precision machinery: Cold-drawn seamless steel pipes with accuracy up to H8 grade, inner wall roughness Ra0.4μm, meet the needs of hydraulic supports and injection molding machine cylinder bodies.
Heat exchangers: Duplex stainless steel pipes are resistant to chloride ion corrosion, and the heat exchange efficiency in seawater desalination devices is 15% higher than that of copper pipes.
Future Engineering—Emerging Technology Fields
Hydrogen storage and transportation: High-pressure gaseous hydrogen transmission steel pipes (working pressure 70 MPa), using special threaded connection technology, to achieve zero leakage.
CCUS projects: 3PE anti-corrosion steel pipes are used for carbon dioxide sequestration pipelines, with a temperature resistance of up to 120℃, ensuring the safe operation of the carbon capture system.
