Application of Line Pipe
Oil and Gas Transportation
Line pipes are essential in the oil and gas industry, used for the long-distance transmission of crude oil, natural gas, and related products. Their strength and corrosion resistance ensure safe and efficient flow across challenging environments.
Water Supply Networks
In municipal and industrial water systems, line pipes are widely applied for large-scale water distribution, offering reliability, durability, and long service life under continuous operation.
Structural Engineering
Beyond fluid transport, line pipes are also used for structural support in construction—such as bridge columns, frameworks, and infrastructure components—thanks to their high mechanical strength and versatility.

Common Materials of Line Pipe
Carbon Steel (API 5L Gr. B, ASTM A106/A53)
Widely used in oil, gas, and water pipelines, carbon steel offers high strength, excellent weldability, and reliable performance under moderate temperature and pressure conditions.
High-Strength Low-Alloy Steel (HSLA)
Designed for enhanced mechanical properties, HSLA steels provide superior resistance to corrosion and abrasion, making them ideal for harsh environments and long-distance pipelines.
Alloy Steel (P11, P22, etc.)
These grades feature added alloying elements for improved heat resistance and strength, commonly used in high-temperature applications such as power plants and refineries.
Stainless Steel (304, 316L)
Renowned for outstanding corrosion resistance, stainless steel line pipes are suitable for aggressive chemical environments, offshore installations, and sanitary water systems.
Duplex and Super Duplex Stainless Steel
Offering a balance of strength and corrosion resistance, these grades are optimal for highly corrosive environments, including seawater and chemical transport.
