Frequently Asked Questions
Q: What makes FRP/GRP pipes better than concrete or steel for water pollution control?
FRP pipes offer superior chemical resistance, meaning they won't rust or degrade when transporting corrosive pollutants. They are also significantly lighter and have a smoother internal surface, reducing maintenance and energy costs.
Q: How does the resin-mortar layer improve pipe performance?
The resin-mortar layer is positioned in the lower stress area of the pipe wall. It increases overall stiffness and rigidity without compromising the tensile strength provided by the filament-wound fiberglass layers.
Q: Can FRP pipes be customized for different chemical environments?
Yes. The inner corrosion-resistant liner is specifically selected based on the media being transported. We use high-content resin and E-glass surfacing mats to ensure maximum protection against specific chemicals.
Q: What is the impact of the smooth inner surface on project investment?
Due to the very low friction factor and high water conservancy factor (C=140-150), these pipes increase capacity by 20%. This allows engineers to use smaller diameter pipes to achieve the same flow rate, reducing overall project investment.
Q: How is the structural integrity of these pipes guaranteed?
Integrity is ensured through a computer-controlled winding process. Continuous strand fiberglass roving is wound to specific designs, maintaining a resin content of 20-40% to resist foreign loads and ensure long-term stiffness.
Q: What are the typical applications for these FRP pipes?
They are widely used across the petroleum industry, chemical processing plants, and municipal drainage systems where corrosion resistance and high pressure-bearing capabilities are required.
