Surface Coating & Anti-Corrosion Services - 3PE Coating

3PE coating, or Three-Layer Polyethylene Coating, is a high-performance anti-corrosion system widely used for steel pipelines in oil & gas, water, and industrial projects. The coating consists of three layers:

Fusion Bonded Epoxy (FBE) Primer: Provides strong adhesion to the steel surface and excellent corrosion resistance.

Adhesive Copolymer Layer: Acts as a bonding bridge between the primer and the outer polyethylene layer.

Polyethylene Outer Layer: Provides mechanical protection against impact, abrasion, and environmental wear.

The combination of these three layers ensures long-term protection even under extreme environmental conditions, making 3PE the industry standard for buried and exposed pipelines.

Technical Features

Superior Corrosion Resistance: Protects steel from soil, moisture, chemicals, and aggressive environments, extending the service life of pipelines.

Impact & Abrasion Resistance: The polyethylene outer layer shields the pipe from mechanical damage during transportation, installation, and service.

Wide Temperature Range: Designed to operate effectively in temperatures ranging from -40°C to +80°C, suitable for diverse climatic conditions.

Uniform & Durable Coating: Ensures consistent thickness, smooth surface, and strong adhesion, minimizing the risk of coating defects.

Eco-Friendly & Safe: 3PE is free from harmful solvents and VOCs, complying with environmental regulations.

Applications

Long-Distance Transmission Pipelines: Ideal for oil, gas, and water pipelines spanning hundreds of kilometers.

Onshore & Buried Pipelines: Protects pipelines buried underground from soil corrosion and moisture ingress.

Industrial Piping Systems: Suitable for chemical, power, and water treatment industries.

Marine & Coastal Pipelines: Provides reliable corrosion protection for pipelines in challenging offshore or coastal environments.

Advantages for Clients

Extended Service Life: Reduces corrosion risk and maintenance frequency, saving long-term costs.

Mechanical Protection: Guards against scratches, dents, and abrasion during handling, transportation, and installation.

International Standards Compliance: Manufactured and applied according to ISO 21809-1, DIN 30670, and NACE SP0198, ensuring reliability for global projects.

Compatibility: Can be applied to pipes of various diameters, wall thicknesses, and steel grades, including API, ASTM, and EN standards.

Conclusion

3PE coating is the industry-leading solution for pipeline corrosion protection, combining chemical resistance, mechanical durability, and long-term performance.
