What is a Fiberglass Pipe?

Fiberglass pipe, fully named Fiberglass Reinforced Plastic (FRP) Pipe, is a composite pipe made by using glass fiber as the reinforcement material and thermosetting resin (such as epoxy, polyester, or vinyl ester resin) as the matrix. It is manufactured through processes like filament winding or pultrusion.

Core Characteristics

1. Excellent Corrosion Resistance: Its greatest advantage. It resists corrosion from acids, alkalis, salts, seawater, soil, and various chemicals, requiring no additional anti-corrosion coating and offering a long service life.

2. Lightweight yet High Strength: Much lighter than steel pipe (about 1/4 the weight) but with a high specific strength, making it easy to transport and install.

3. Smooth Inner Wall: Low fluid friction resistance, resistance to scaling, maintaining high flow capacity over time and saving energy.

4. Long Service Life: The design service life is typically 50 years or more, with low maintenance costs.

Main Types

• Filament Wound Pipe: High pressure resistance, often used for high-pressure applications, like water injection lines in the oil industry.

• Centrifugally Cast Pipe: Very high stiffness, commonly used for large-diameter pipes in municipal water supply and drainage.

• Pultruded Pipe: Mainly used for non-pressure or low-pressure applications such as cable protection conduits.

Common Applications

• Oil & Gas Industry: Oilfield water injection, crude oil gathering and transmission, chemical pipelines.

• Municipal Engineering: Potable water, sewage, and reclaimed water pipelines.

• Marine & Power Industries: Seawater desalination systems, circulating cooling water systems.

• Mining Industry: Tailings and slurry transportation pipelines.

In summary, Fiberglass pipe is a high-performance solution for replacing traditional metal pipes in harsh corrosive environments, known for its life-cycle economy and reliability.
