Three-layer polypropylene for high-temperature pipeline applications
3LPP is the premium choice for high-temperature applications where polyethylene cannot deliver the performance required. The three-layer structure mirrors 3LPE but features a polypropylene topcoat, enabling continuous service up to 110°C—a significant advantage in deep-water offshore, high-temperature gas, and industrial process piping applications.
This advanced coating system combines the proven FBE primer and copolymer adhesive of 3LPE with a PP topcoat that exhibits superior mechanical strength and heat resistance. Essential for pipelines operating in demanding thermal environments where durability and reliability are non-negotiable.
Fully compliant with ISO 21809-1 and DIN 30678 standards, 3LPP delivers the thermal performance and longevity required for next-generation pipeline infrastructure.
3LPP handles continuous temperatures up to 110°C, compared to 3LPE's 80°C limit. Perfect for deep-water offshore and high-temperature applications.
Polypropylene's rigid molecular structure provides enhanced abrasion and impact resistance in demanding subsea and installation environments.
Ideal for high-temperature gas, steam, and thermal circulation applications where PE would degrade or fail prematurely.
Superior flexibility and strength make 3LPP ideal for HDD and other trenchless installation methods in challenging terrain.
