In the underground water pipe system, durability and corrosion resistance directly determine the engineering lifespan. The revolutionary polypropylene lined pipes we have launched, with advanced spiral submerged arc welding technology, have become the preferred solution for groundwater transportation, featuring excellent quality and long-lasting durability, perfectly meeting the high standards of groundwater supply and suitable for various application scenarios. And the key to upgrading the performance of this cutting-edge product is the addition of the FBE ARO coating.
The 3LPE (three-layer polyethylene) coating pipe itself has basic anti-corrosion and mechanical protection capabilities, but the underground environment is complex, with rock friction during transportation and installation, backfill impact, and corrosive media such as acids, alkalis, and salts in the soil, which may damage the outer polyethylene and affect the integrity of the pipe. The FBE ARO coating, as a dual-effect protection system combining fusion-bonded epoxy (FBE) and wear-resistant outer coating (ARO), precisely fills this gap.
The FBE coating is closely bonded to the steel pipe substrate, forming the first line of anti-corrosion barrier, effectively blocking the penetration of moisture and corrosive substances; the ARO coating provides extremely strong wear resistance and impact resistance, protecting the pipe from physical damage during installation and long-term use. The synergy of the two not only doubles the anti-corrosion and anti-wear performance of the 3LPE coated pipe, but also meets the strict standards of groundwater supply, extending the lifespan of the pipe.
This polypropylene lined 3LPE coated pipe with FBE ARO coating integrates structural strength and dual protection perfectly, providing reliable guarantees for municipal water supply, industrial groundwater transportation and other scenarios, and becoming the ultimate solution for underground water pipe systems.
