Introduction to FRP-Plastic Composite Pipe

FRP-Plastic Composite Pipe is a high-performance pipe that combines glass fiber reinforced plastic (FRP) with thermoplastics (such as HDPE, PP, PVC, etc.) through a special process. It has the high strength and corrosion resistance of FRP and the flexibility and sealing of plastics, and is widely used in harsh environments such as chemical, municipal, and marine.

Product performance

• Mechanical properties

Tensile strength ≥ 200MPa, ring stiffness ≥ SN5000, pressure bearing capacity can reach 1.6-4.0MPa.

• Corrosion resistance

Can withstand acid, alkali, salt spray, organic solvents, etc., with a service life of more than 30 years (3-5 times that of ordinary steel pipes).

• Lightweight and high strength

The density is only 1/4 of that of steel pipes, which is easy to install and reduces transportation costs.

• Fluid characteristics

The inner wall is smooth (roughness coefficient 0.0084), and the flow rate is 20%-30% higher than that of metal pipes.

• Environmental adaptability

Working temperature: -40℃~120℃, some models can withstand higher temperatures.

Advantages and characteristics

• Synergistic effect of dual materials

The plastic layer is anti-seepage and anti-corrosion, and the fiberglass layer is pressure-resistant and impact-resistant, solving the limitations of a single material.

• Long life and low maintenance

No need for cathodic protection, no painting, and reduced downtime maintenance costs.

• Customized design

Adjustable resin type (such as corrosion-resistant vinyl ester resin) and fiber layer thickness to adapt to different working conditions.

• Environmental protection and energy saving

Production energy consumption is lower than that of metal pipes, 100% recyclable, and meets green building standards.

Application areas

1.Chemical industry

Acid/alkali transmission pipelines, exhaust gas treatment tower connecting pipes.

2.Municipal engineering

Water supply and drainage network, reclaimed water reuse, fire protection pipelines.

3.Ocean and ships

Seawater desalination pipelines, dock anti-corrosion pile pipes.

4.Power and energy

Power plant desulfurization system, oil and gas field corrosive medium transportation.

5.Mining and metallurgy

Slurry transportation, tailings discharge pipelines.

Glass fiber reinforced plastic composite pipes are gradually replacing traditional metal pipes and pure plastic pipes with their excellent corrosion resistance, lightweight design and long life. Our factory adopts automated production lines and strictly follows international standards such as ISO and ASTM to provide customers with full-specification products and customized solutions from DN50 to DN3000.
