Three-layer polyethylene corrosion protection for pipelines
The 3LPE coating system provides advanced three-layer corrosion protection for buried and submerged pipelines. This proven technology is the industry standard for long-distance pipeline applications requiring maximum durability and performance.
Layer 1 - FBE Primer: Provides foundational adhesion and corrosion resistance
Layer 2 - Copolymer Adhesive: Bonds the protective layers together for structural integrity
Layer 3 - PE Topcoat: Offers mechanical and environmental protection against external corrosion
The system operates at 180-230°C with precision thickness control, ensuring consistent quality across all applications. Fully compliant with ISO 21809-1, DIN 30670, and API 5L standards.
