Features

1. Advanced Coating Technologies:  

   - 3PE (3-Layer Polyethylene) Coating: Combines epoxy, adhesive, and polyethylene layers for maximum protection against soil stress and moisture.  

   - Fusion-Bonded Epoxy (FBE): Thermally bonded epoxy coating provides chemical resistance and adhesion strength.  

   - Galvanization: Hot-dip galvanizing forms a zinc barrier to prevent oxidation.  

   - Internal Cement Mortar Lining: Protects against water corrosion in potable water systems.  

2. Material Options:  

   - Base pipes include carbon steel, stainless steel, or alloy steel, tailored to project requirements.  

3. Durability:  

    - Service life extended by 20–50 years, depending on coating type and environmental exposure.  


Applications  

- Oil & Gas: Subsea pipelines, refinery piping, and chemical transport.  

- Water Infrastructure: Municipal water supply, sewage systems, and desalination plants.  

- Renewable Energy: Geothermal and solar thermal systems.  

- Industrial: Cooling systems, acid storage, and mining slurry transport.  

- Marine: Port pilings, offshore platforms, and shipbuilding.  


Advantages  

Multi-Layer Defense: Dual external/internal coatings for comprehensive protection.  

Custom Solutions: Coatings optimized for specific environments (e.g., high salinity, acidic soils).  

Compliance: Meets ISO 21809, AWWA C210, and NACE standards.  

Cost Efficiency: Reduces maintenance and replacement costs over the pipe’s lifespan.  


Our Capabilities  

In-House Coating Facilities: State-of-the-art production lines for 3PE, FBE, and galvanizing.  

Testing & Certification: Hydrostatic tests, holiday detection, and thickness inspections.
