Various sizes of FRP pipes ready for municipal and industrial applications.
At Hebei Leihong FRP Technology Co., Ltd., we specialize in manufacturing high-performance fiberglass reinforced plastic (FRP/GRP) pipes designed to meet the diverse needs of wastewater treatment plants (WWTPs), municipal sewage networks, and industrial odor control systems. The image above showcases a selection of FRP pipes in multiple diameters, symbolizing the versatility and scalability of our products.
Custom Diameters, One Purpose: Reliable Flow Management
Our FRP pipes are available in a wide range of diameters-from small-diameter pipes used for chemical dosing or air extraction, to large-diameter pipes suitable for high-capacity sewage transport or odor gas collection. Whether used underground for wastewater flow or aboveground for exhaust systems, these pipes are engineered for durability, safety, and long-term performance.
Ideal for Wastewater and Sewerage Projects
In municipal and industrial settings, corrosion, leakage, and environmental compliance are key challenges. FRP pipes offer unmatched corrosion resistance to acids, sulfides, and moisture, making them ideal for:
- Underground sewage transmission
- Sludge return lines in WWTPs
- Effluent discharge pipelines
- Overflow and ventilation systems
Thanks to their lightweight yet high-strength structure, FRP pipes reduce installation time and labor costs, while their long service life (up to 50 years) ensures low maintenance and reliability over time.
Reliable for Exhaust and Odor Control Applications
FRP pipes are widely used in odor control systems for transporting corrosive gases such as hydrogen sulfide (H₂S) and ammonia (NH₃). Their smooth inner surface ensures efficient gas flow with minimal pressure loss, and the chemical-resistant properties help maintain air quality compliance in sensitive environments like:
- WWTP deodorization units
- Spray towers and biofilters
- Covered grit chambers and sludge tanks
A Smarter Choice for Sustainable Infrastructure
As environmental standards continue to rise, engineering firms and municipalities are seeking more durable, cost-effective, and environmentally friendly piping solutions. FRP pipes provide all of these benefits, combining structural strength, chemical stability, and design flexibility into one solution. Whether for municipal sewer systems, industrial ventilation, or plant-wide waste piping networks, our fiberglass pipe systems are a smart investment in long-term infrastructure performance.
