Surface Coating & Anti-Corrosion Services - 3PP Coating

3PP coating, or Three-Layer Polypropylene Coating, is an advanced pipeline anti-corrosion system designed for high-temperature and highly demanding environments. Structurally similar to 3PE coating, it consists of:

Fusion Bonded Epoxy (FBE) Primer: Provides excellent adhesion to the steel substrate and initial corrosion protection.

Adhesive Copolymer Layer: Bonds the primer to the outer polypropylene layer, ensuring long-term coating integrity.

Polypropylene (PP) Outer Layer: A high-performance polymer layer that offers superior mechanical, chemical, and thermal resistance.

This combination ensures robust corrosion protection, mechanical durability, and thermal stability, making 3PP the preferred choice for pipelines operating under elevated temperatures or harsh environmental conditions.

Technical Features

High-Temperature Resistance: Designed to withstand continuous operating temperatures of up to 110°C, suitable for hot oil, gas, and steam pipelines.

Superior Mechanical & Abrasion Resistance: The polypropylene outer layer protects pipes from scratches, impact, and wear during transportation, handling, and installation.

Excellent Corrosion Resistance: Protects steel from soil, water, chemicals, and other corrosive agents, ensuring long-term pipeline performance.

Uniform & Durable Coating: Ensures consistent thickness and smooth, defect-free surface, preventing weak points that may lead to coating failure.

Long-Term Reliability: The combination of epoxy primer, adhesive layer, and polypropylene ensures exceptional adhesion and coating longevity.

Applications

High-Temperature Oil & Gas Pipelines: Ideal for pipelines transporting crude oil, refined products, or steam at elevated temperatures.

Onshore & Offshore Pipelines: Provides reliable protection in both buried and exposed pipelines, including marine and coastal environments.

Industrial Piping Systems: Suitable for chemical plants, refineries, and power stations where high-temperature corrosion resistance is critical.

Specialized Transmission Lines: Used for pipelines requiring both mechanical protection and thermal resistance.

Advantages for Clients

Extended Operational Lifespan: Reduces corrosion and maintenance needs even under high-temperature operating conditions.

Enhanced Mechanical Protection: Polypropylene outer layer guards against impact, abrasion, and external stress.

Compliance with International Standards: Produced according to ISO 21809-1, DIN 30670, NACE SP0198, and other global standards, ensuring quality and reliability for worldwide projects.

Versatility: Suitable for a wide range of pipe diameters, wall thicknesses, and steel grades (API, ASTM, EN), providing flexible solutions for complex projects.
