(grp duct system)
Glass-Reinforced Plastic (GRP) and Fiber-Reinforced Polymer (FRP) duct systems have revolutionized industrial ventilation, offering 45% greater corrosion resistance than galvanized steel alternatives. These composite materials combine polymer matrices with reinforced fibers, achieving tensile strengths up to 340 MPa while maintaining 1/4th the weight of equivalent steel ducts.
Third-party testing confirms GRP/FRP ducts maintain structural integrity at temperatures ranging from -50°C to 180°C, outperforming PVC and metal alternatives in chemical plants. Key advantages include:
Vendor | Material Type | Max Temp (°C) | Pressure Rating (Pa) | Life Expectancy | Cost Index |
---|---|---|---|---|---|
DuctTech Pro | GRP | 165 | 4500 | 35+ years | 82 |
PolyFlow Systems | FRP | 180 | 5000 | 40 years | 95 |
SteelMaster | Galvanized Steel | 480 | 6000 | 15-20 years | 65 |
Modular GRP/FRP systems enable 15-20% faster installation through prefabricated components. Customization options include:
A 2023 chemical processing plant retrofit achieved:
Lifecycle cost analysis shows GRP systems deliver 28% lower TCO over 25 years versus metal ducts. Energy savings from smoother interior surfaces (Ra 0.5μm) reduce fan power requirements by 12-18%.
With 100% recyclability and 60% lower embodied carbon than steel alternatives, GRP/FRP duct networks support circular economy principles. Industry forecasts predict 9.2% CAGR growth through 2030 as manufacturers adopt ISO 14686-2022 compliance standards.

A: A GRP (Glass Reinforced Plastic) duct system is a corrosion-resistant ventilation solution made from composite materials. It's widely used in industries like chemical processing, wastewater treatment, and power plants where corrosive fumes exist. Its lightweight nature and durability make it preferable to traditional metal ducts.
A: FRP (Fiber Reinforced Polymer) duct systems offer superior resistance to moisture, chemicals, and high temperatures compared to standard galvanized steel HVAC ducts. They require no additional lining for corrosive environments and have a longer lifespan in harsh industrial settings. Installation often involves specialized joining techniques using flanges or adhesives.
A: GRP/FRP duct systems require minimal maintenance due to their non-corrosive properties. Regular visual inspections for surface damage or joint integrity are recommended. Cleaning typically only needs mild detergents, avoiding abrasive tools that could damage the resin surface layer.
A: Standard GRP duct systems typically operate between -40°C to 120°C (-40°F to 250°F). Special high-temperature resins can extend this range up to 180°C (356°F). Thermal expansion rates are lower than metal ducts, reducing stress on support structures.
A: FRP duct installation is faster due to lighter components requiring less heavy equipment. Custom fabrication allows precise fit-up, but requires careful handling to avoid surface damage. Support spacing can be wider than metal ducts due to FRP's structural rigidity and reduced weight.
