Excellent oil and chemical resistance: Can withstand long-term immersion in non-aromatic oils such as crude oil, diesel, kerosene, and petrochemical by-products. The material remains stable and is not easily swollen (Note: not resistant to gasoline with high aromatic content or benzene-based solvents).
High wear resistance and low flow resistance: Smooth inner wall with a friction coefficient only 1/6 that of steel pipes. Low energy consumption during transport, resistant to wax formation, and wear resistance 4-8 times that of steel pipes, suitable for gathering and transportation of sandy crude oil.
Super flexibility and resistance to geological deformation: Elongation at break can exceed 500%, able to adapt to foundation settlement, earthquakes, and other geological changes without risk of brittle fracture. Particularly suitable for laying in swamps, permafrost, hills, and other complex terrains.
Full lifecycle corrosion resistance: No additional anti-corrosion coating needed, resistant to acids, alkalis, salts, and microbial corrosion in the soil. Underground service life can exceed 50 years, significantly reducing maintenance costs.
Lightweight and easy to construct: Density about 1/8 of steel pipes. Transportation and lifting do not require large equipment, long-distance coil laying is possible, reducing the number of joints and shortening the construction period.
