3-Layer Coatings

Enhancing Performance, Ensuring Durability
Three-layer coatings for pipelines consist of an epoxy primer, an adhesive polyolefin intermediate layer, and a topcoat, providing a robust defense against corrosion, mechanical impact, and environmental degradation. This advanced coating system ensures superior adhesion and longevity, adapting to varying temperatures and harsh operational conditions. Its comprehensive protection capabilities make it an indispensable solution for safeguarding the integrity and efficiency of modern pipeline infrastructures across the globe.

3-Layer Polyolefin (3LP)

The 3LP coating combines an FBE primer, polymeric adhesive, and a DHPO extruder jacket, providing a robust thickness of 40 to 60 mils and suitable for pipe diameters ranging from 6 inches to 48 inches. This coating system excels in rugged and moist environments, offering enhanced mechanical protection, superior adhesion, and excellent resistance against cathodic disbondment, making it ideal for pipelines that undergo directional drilling or are placed in moderately rocky terrains. Compliant with CSA Z245.21 standard, the 3LP coating is designed for pipe lengths between 35 feet and 80 feet, ensuring moisture and soil resistance which allows for higher operating temperatures.

3-Layer Polyethylene (3LPE)

The 3LPE coating system integrates an FBE primer, a polymeric adhesive, and an HDPE extruder jacket to deliver unparalleled pipeline protection. With minimum thicknesses set at 10 mils for FBE, 8 mils for the adhesive, and 40 mils for the HDPE jacket, this system ensures durable stability and coverage. Featuring a maximum operating temperature of 85°C and a minimum handling temperature of -40°C, the 3LPE coating is engineered for diverse environmental conditions, offering robust protection against physical and chemical stressors.

3-Layer Polypropylene (3LPP)

The 3LPP coating system is meticulously designed to safeguard pipelines, combining an FBE primer, a robust polymeric adhesive, and a high-density polypropylene (HDPP) extruder jacket. It stipulates minimum thickness requirements of 10 mils for the FBE, 8 mils for the adhesive, and 40 mils for the HDPP layer, creating a formidable barrier against environmental threats. Tailored for extreme conditions, 3LPP can withstand temperatures up to 145°C while maintaining its integrity at temperatures as low as -40°C, making it an optimal choice for pipelines operating under severe thermal stresses.
