Fiberglass Drainage Pipe
Fiberglass Drainage Pipe is a non-metallic composite drainage pipe made of fiberglass, thermosetting resin, and quartz sand with a sand layer, which is wrapped and formed. It is specifically used for municipal sewage, rainwater, industrial wastewater, chemical wastewater, etc.
Core performance
1. Super strong corrosion resistance
-Resistant to domestic sewage, industrial acid and alkali, salt, seawater, hydrogen sulfide, and oil pollution
-No rust, no corrosion, no scaling
-Lifespan: 20-50 years, concrete/steel pipes generally 5-10 years
2. Lightweight and high-strength
-Density: 1.8-2.1 g/cm ³
-Weight ≈ 1/4 of steel pipe, 1/10 of concrete pipe, can be lifted manually, small crane is sufficient
-Ring stiffness: SN3000- SN10000 N/m ²
3. Excellent hydraulic performance
-The inner wall is extremely smooth, with Manning’s coefficient n=0.008-0.009 (concrete pipe ≈ 0.013)
-Same diameter flow rate can be increased by 20% -30%, or the first diameter can be reduced to save money
-Long term no scaling, no deterioration of water flow capacity
Common specifications (mainstream in drainage engineering)
-Caliber: DN100-DN4000mm
-Pressure rating: 0.2-1.6MPa (drainage is mostly 0.2-1.0MPa)
FRP pipe and GRP pipe systems are used for wastewater drainage, chemical fluid transfer, ventilation and industrial piping projects, offering corrosion resistance, lightweight structure and custom diameters.
