FRP/GRP Flange

Product Introduction

FRP flanges are essential components in piping systems made of Fiberglass Reinforced Plastic (FRP). They are designed to securely connect FRP pipes, valves, and other equipment, providing a reliable and leak-proof joint. Manufactured using the hand lay-up process with high-quality resins such as epoxy, vinyl ester, or polyester, these flanges are lightweight, high-strength, and highly corrosion-resistant.

Customizable according to customer specifications, FRP flanges allow for precise adjustments in dimensions. They are widely used in industries that demand excellent corrosion resistance, durability, and lightweight construction, including chemical processing, water treatment, and Flue Gas Desulfurization (FGD) systems.

Product Advantages

1. Excellent Corrosion Resistance
FRP flanges are highly resistant to a wide range of corrosive chemicals, including acids, alkalis, and salts, making them ideal for harsh environments like FGD systems and chemical plants.

2. Lightweight and High Strength
FRP flanges are significantly lighter than traditional metal flanges (e.g., steel or stainless steel), reducing transportation and installation costs. Despite their lightweight, they offer high mechanical strength and rigidity, ensuring reliable performance under pressure.

3. Durable and Long-Lasting
FRP flanges have a long service life, even in corrosive and abrasive environments, reducing the need for frequent replacements.

4. Smooth Surface Finish
The smooth surface of FRP flanges minimizes friction and prevents the buildup of deposits, ensuring efficient fluid flow.

5. Customizable Design
FRP flanges can be manufactured in various sizes, pressure ratings, and configurations (e.g., slip-on, weldneck, blind) to meet specific project requirements.

6. Thermal and Electrical Insulation
FRP flanges provide excellent thermal and electrical insulation, making them suitable for applications involving high temperatures or electrical hazards.

7. Cost-Effective
Lower material and maintenance costs compared to metal flanges, offering a cost-effective solution for corrosive environments.
