FRP / GRP Ducting Systems
frp ducting, grp ducting, frp ductwork solutions from leading frp duct manufacturers and frp ductwork manufacturers are engineered for high-performance industrial environments. Our complete frp ducting system includes design, manufacturing, and frp duct installation, supported by a competitive frp duct price list.
We also supply frp duct rodder, along with a complete range of frp duct and fittings and grp duct and fittings, manufactured using thermoset frp duct technology in accordance with the thermoset frp duct construction manual.
FRP/GRP ducting is engineered for safe and efficient transport of corrosive gases, fumes and vapors in industrial ventilation and environmental control systems. Unlike metallic ducting, which deteriorates in acidic, alkaline or moisture-rich conditions, FRP/GRP ducting provides long-term stability, excellent corrosion resistance and reliable airflow performance.
SREX Composites manufactures a full range of FRP/GRP ducting systems used in fume extraction, exhaust ventilation, scrubber interconnections and air-pollution-control applications. Our systems ensure consistent performance in industries that demand dependable non-metallic ducting for continuous operation.
Industrial Applicability
Why FRP/GRP for Ducting?
Applications within Environmental & Process Systems
Industrial Applicability
FRP/GRP ducting is widely used in:
- Chemical and petrochemical plant ventilation
- Acid and alkali fume extraction
- Scrubber inlet/outlet duct networks
- Battery and metal finishing exhaust systems
- Chlorination, bromination and halogen fume zones
- ETP and wastewater-treatment vent systems
- Pharmaceutical & API manufacturing ventilation
- Semiconductor corrosive gas extraction
- Mining / metallurgical process exhaust channels
These ducts ensure safe handling of corrosive gases where metal systems cannot withstand long-term exposure.
Why FRP/GRP for Ducting?
- Excellent resistance to chemical vapors and corrosive fumes
- Stable operation in high-humidity or condensation-rich atmospheres
- Lightweight, reducing load on supports and structures
- Smooth internal bore for efficient airflow
- No rusting, pitting or internal scaling
- Low maintenance and long lifecycle
- Compatible with scrubbers, chimneys, blowers and filtration systems
Applications within Environmental & Process Systems
- Wet scrubber interconnecting ducts
- Industrial exhaust manifolds
- VOC and hazardous fume removal systems
- Mist eliminator exhaust sections
- Process gas collection and transfer
- Emission-control and neutralization units
- Industrial air-handling and extraction systems
Thermoplastic-Lined FRP/GRP Ducting
For extreme fume and gas environments where elevated chemical resistance is required, SREX Composites manufactures thermoplastic-lined FRP/GRP ducting. These systems combine:
- A corrosion-resistant thermoplastic liner, and
- A reinforced FRP/GRP structural shell
This dual-layer construction provides exceptional resistance to aggressive vapors, halogen gases, mixed acids, solvent fumes and high-temperature exhaust streams.
Seamless vs. Non-Seamless Liners
- Seamless thermoplastic liners are available up to 300 mm diameter
These are produced as joint-free liners offering the highest level of internal corrosion resistance and smooth airflow characteristics. - For diameters above 300 mm, the thermoplastic liner cannot be seamless
Larger liners are fabricated using welding, thermoforming or segmental forming techniques and bonded to the FRP/GRP shell.
These non-seamless liners still provide excellent chemical resistance and allow manufacture of large-diameter ducting widely used in industrial ventilation systems.
