Fiberglass Cable Protection Tube: Specifications, Characteristics and Applications

FRP Cable Protection Pipe is a composite material pipe made of resin as the matrix and glass fiber as the reinforcement material, which is specially used for laying and protecting various cables. Compared with traditional metal or PVC pipes, FRP pipes have better corrosion resistance, insulation and mechanical strength.

In the construction of modern power facilities, the selection of cable protection pipes is crucial. With its excellent performance and reliable quality, FRP cable protection pipes have become the preferred product in the power, communication and other industries. As a professional FRP manufacturer, we will introduce you to the various characteristics and applications of this product in detail.

Advantages of FRP Cable Protection Pipes

1.Strong and tough:

resistant to rolling and impact, adaptable to geological movements such as earthquakes, preferred for heavy loads/seismic areas.

2.Top corrosion resistance:

resistant to strong acids, alkalis, and salt spray, with a lifespan of 50+ years (3-5 times that of metal pipes), durable in humid/chemical areas.

3.Electricity safety:

high insulation to prevent leakage, non-magnetic and power-saving, flame retardant from -50℃ to 130℃, first choice for flammable and explosive scenes.

4.Lightweight and cost-saving:

the weight is only 1/4 of that of steel pipes, with fast installation and short construction period, and a full-cycle cost that is 20%-40% lower.

5.Green and low-carbon:

environmentally friendly and recyclable, low production energy consumption, helping projects obtain green certification, and meeting the dual carbon goals.

6.Full-scene adaptation:

UV resistance (20 years in the open air), -50℃ low temperature resistance, and general use in severe cold/strong UV areas.

Installation and Maintenance Guide

Preparation before installation

Check the appearance quality of the pipeline, Prepare special connectors and sealing materials, Measure and lay out, determine the laying path

Installation steps

• Trench excavation: width ≥ pipe diameter + 300mm
• Foundation treatment: lay 100mm thick sand cushion
• Pipeline laying: socket facing the direction of water
• Connection treatment: ensure that the sealing ring is in place
• Backfill compaction: backfill in layers, each layer ≤ 300mm

Maintenance

• Regularly check the joint sealing
• Clean up the accumulation at the pipe mouth
• Avoid long-term pressure from heavy objects

Purchase Suggestions

• Choose the appropriate pipe diameter according to the cable specifications
• Consider environmental conditions to determine the pressure level
• Choose products from regular fiberglass manufacturers
• Request product test reports and certificates

FAQ

Q: How long is the service life of FRP cable protection tube?

A: Under normal use conditions, the service life can reach more than 50 years.

Q: How to judge the quality of the product?
