Our 3PE anti-corrosion steel pipes boast several outstanding properties: The product’s polymer structure is stable and anti-aging, with a service life exceeding 50 years under normal operating conditions; its strong molecular stability resists corrosion from natural gases and various chemical media in soil, eliminating the need for additional anti-corrosion components. The pipes exhibit excellent toughness, with an elongation at break exceeding 500%, and good flexibility, allowing for bending and bypassing obstacles during construction, reducing the use of fittings and lowering installation costs. The applicable temperature range is -60℃ to 60℃; it is not prone to brittleness at low temperatures, exhibits outstanding impact and seismic resistance, can adapt to uneven foundation settlement, and is less prone to damage during winter construction.
