Advantages of FRP Rectangle Tubes

1. Excellent corrosion resistance

FRP rectangle tubes are made from materials such as epoxy resin and high molecular weight unsaturated polyester resin, which effectively resist acid and alkali corrosion in practical applications. They are also suitable for transporting some corrosive chemical reagents and liquids.

2. Lightweight and easy to install and maintain

FRP rectangle tubes are lightweight and easy to install and maintain, offering convenience in various applications.

3. Good wear resistance

Especially in highway bridge construction, when concrete is poured into FRP rectangle tubes, the wear on the inner walls of the tubes is almost negligible, demonstrating their excellent wear resistance.

4. Outstanding anti-aging performance

FRP rectangle tubes can be used in harsh natural environments with temperatures ranging from -40°C to 70°C for extended periods. Ultraviolet absorbers can be added during the manufacturing process to avoid UV radiation damage, further enhancing the anti-aging properties of the tubes.

5. Prominent frost resistance

In environments with temperatures as low as -40°C, even if the liquid inside the FRP rectangle tubes freezes, the tubes will not crack due to frost.

6. Superior heat and high-temperature resistance

FRP rectangle tubes can withstand temperatures up to 150°C without softening or deforming, making them suitable for use as insulating materials in engineering applications.

7. Exceptional dimensional stability

Once formed, FRP rectangle tubes maintain excellent stability under normal conditions. They will not expand or contract due to temperature fluctuations, as long as the environmental temperature and the load on the tubes remain constant.

8. Good electrical insulation performance

The manufacturing process of FRP rectangle tubes includes glass fibers and epoxy resin materials, which are inherently insulating. The addition of mica as a filler further enhances the insulation properties, making the tubes immune to electrochemical corrosion and stray current corrosion.

9. Long service life and high cost-performance ratio

The normal service life of FRP rectangle tubes can reach over 20 years. Their lightweight characteristics result in lower transportation and installation costs, making them a relatively low-cost engineering material for tubes and fittings.

10. Excellent surface properties

When FRP rectangle tubes come into contact with acidic or alkaline substances, their surfaces rarely exhibit corrosion products. Unlike metal tubes, they do not corrode or rust.
