FRP PIPE
Fiberglass pipes are lightweight and economical pipes that can replace steel, iron, and concrete pipes.The core advantages of FRP continuously wound pipe lie in its high strength, high rigidity, excellent corrosion resistance, superior hydraulic performance, superior leak resistance, and the economic and length advantages afforded by continuous production. It seamlessly integrates materials science with advanced manufacturing processes, offering a high-performance, cost-effective, and environmentally friendly modern engineering piping solution, particularly suited for long-distance, high-flow, and corrosive transport.
Fiberglass reinforced plastic (FRP) circulating pipes are composite material pipes made primarily of resin, glass fiber, and quartz sand. They possess excellent corrosion resistance, are lightweight yet high-strength, and have a long service life, making them widely used in circulating water systems, chemical, power, and oilfield applications.
Products Description
Fiberglass reinforced plastic (FRP) circulating pipes are composite material pipes made primarily of resin, glass fiber, and quartz sand. They possess excellent corrosion resistance, are lightweight yet high-strength, and have a long service life, making them widely used in circulating water systems, chemical, power, and oilfield applications.
Strong Corrosion Resistance: Suitable for high-salt, strong acid and alkaline media (such as seawater, chlorinated wastewater, hydrochloric acid, etc.), avoiding the electrochemical corrosion problems of metal pipes.
Customizable Inner Liner: The inner lining can be customized (e.g., vinyl ester resin or polyvinylidene fluoride resin) to further enhance high-temperature resistance (up to 120℃) and chemical corrosion resistance.
Excellent Hydraulic Characteristics: The smooth inner wall (roughness coefficient only 0.0084) reduces frictional resistance by more than 30% compared to steel pipes, allowing for smaller pipe diameters or lower pump power for the same flow rate, resulting in significant energy savings.
No Scaling Issues During Long-Term Use, Maintaining Stable Flow Rate.
Lightweight, High-Strength, and Long Service Life: Weighing only 1/4 of steel pipes and 1/10 of concrete pipes, facilitating transportation and installation.
Designed for a 50-year lifespan, with low maintenance costs (no anti-corrosion coating or cathodic protection required).
Outstanding economic benefits: Although the initial investment is relatively high (e.g., approximately RMB 11,600/meter for DN3000 pipe), it saves 30%~40% on pump energy consumption and is maintenance-free, resulting in lower overall costs than metal pipes.
Example: A nuclear power plant's circulating water system using fiberglass pipes saved approximately RMB 42.68 million in electricity costs over 50 years.
Typical applications:
Industrial circulating water systems: Cooling water transport in nuclear power plants and thermal power plants, resistant to seawater corrosion and high temperature differences.
Chemical wastewater discharge pipelines: Transporting acidic and alkaline wastewater (e.g., 30% hydrochloric acid, chlorine-containing media), replacing carbon steel lined with plastic.
Oilfield water injection and gathering: Transporting high-mineralization formation water, resistant to soil salinization (Middle Eastern oilfield application case).
Fluorescent gas desulfurization and environmental protection projects: Chimney exhaust pipes adopt anti-static design (lined with graphite flakes or built-in alloy conductive wires).
With its advantages of corrosion resistance, energy saving, and long service life, fiberglass circulating pipes have become the preferred solution for transporting corrosive media.
