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.

Color Customized

Standard Colors: Black, Green, Blue, Yellow

Optional / Custom Colors: Red, White, Orange, Gray, Brown

Special / RAL Colors: Available upon request

Note: Color is for identification and project marking; it does not affect corrosion protection. Custom colors may require MOQ.

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

Long Service Life: Durable underground performance, typically 30–50 years.

Mechanical & Chemical Protection: PE outer layer resists scratches, impacts, UV, and soil chemicals.

Low Maintenance: Reduces repair needs over decades.

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.

Packaging & Transportation

Packaging

Pipes are bundled by size using PET/PP straps, with rubber or wooden spacers to prevent friction.

Plastic end caps are applied to protect bevels and keep pipes clean.

Surfaces are protected with plastic film, woven bags, or waterproof wrapping to prevent moisture and UV exposure.

Use nylon lifting slings only; steel wire ropes must not contact the 3PE coating.

Optional packaging: wooden saddles, steel-frame pallets, or individual wrapping for high-spec projects.

Transportation

Vehicle beds are lined with rubber mats or wooden boards to avoid coating damage.

Pipes are securely fixed with soft straps and separated by blocks to prevent rolling.

Loading/unloading requires multi-point lifting with nylon belts to avoid scratches.

For sea freight, pipes are loaded in 20GP/40GP containers or bulk shipments, with additional moisture protection and optional temporary rust oil on pipe ends.
