FRP Spray Circulation System Pipes
FRP spray circulation system pipes are high-strength and corrosion-resistant pipes made of high-performance resins (such as epoxy resins and unsaturated polyester resins) as the matrix and glass fiber as the reinforcing material through advanced composite processes. Designed specifically for industrial spray and circulating water systems, they can replace traditional metal and PVC pipes and are suitable for harsh chemical environments and long-term outdoor working conditions.
Features & Advantages
Super corrosion Resistance
✅ Completely solve the problems of metal pipeline rust and electrochemical corrosion, suitable for high corrosion scenarios such as desulfurization and electroplating.
Lightweight and Easy to Install
✅ The length of a single pipe can reach 12 meters, reducing the number of connection points and reducing the lifting cost by 30%.
Maintenance-free Design
✅ No anti-corrosion coating is required, no scaling problem, and the cost of the entire life cycle is reduced.
Environmental Protection and Energy Saving
✅ The production energy consumption is only 1/3 of that of steel pipes, and 100% can be recycled.
Customized Service
✅ Supports customization of diameters from DN50 to DN3000mm, and provides a variety of connection methods such as flanges and sockets.
Product Performance
- Corrosion resistance: Tolerant to acid, alkali, salt spray, organic solvents (pH 1-14)
- Strength-to-weight ratio 50% higher than steel pipe, and only 1/4 of the weight of steel pipe
- Pressure resistance: 0.6MPa~2.5MPa (customizable)
Service life More than 20 years (harsh environment) - Fluid resistance Smooth inner wall (roughness 0.0084), small flow loss
- Temperature range -40℃~120℃ (adjusted according to resin type)
Application
- Environmental protection engineering: Flue gas desulfurization (FGD) spray tower circulation pipelines, wastewater treatment plants.
- Chemical industry: Pickling production line, electrolyte transportation, chemical plant circulation cooling system.
- Energy and power: Cooling water system of power plant, auxiliary pipeline of nuclear power plant.
- Marine engineering: Desalination of seawater, ship ballast water treatment.
- Other fields: Process spray systems in papermaking, pharmaceutical, food processing and other industries.
Production Process
Fiber winding molding process
Computer-controlled fiber winding technology is used to ensure that the fibers are evenly laid according to stress distribution.
Inner lining: Spraying corrosion-resistant resin layer to form a smooth and impermeable barrier.
Structural layer: Cross-winding high-tension glass fiber to improve mechanical strength.
Outer protective layer: Add anti-ultraviolet agent to adapt to long-term outdoor use.
Curing and post-processing
High-temperature curing molding to ensure sufficient cross-linking reaction of the resin.
Precision processing of the port to ensure the sealing of the flange connection.
