FRP Insulation Pipes

FRP insulation pipes are a new type of insulation pipes in which fiber wound FRP pipes are used as the conveying pipes, materials such as polyurethane are used as the intermediate insulation layer, and wound FRP pipes are used as the protective layer against external pressure.

Characteristics of FRP Insulation Pipes

1.Lightweight and high-strength, convenient for transportation, installation and maintenance, without the need for heavy lifting equipment.

2.Excellent hydraulic characteristics, smooth inner wall, and small fluid resistance, which can save pumping costs.

3.The inner wall of the pipeline does not scale, and remains smooth after long-term use.

4.Low thermal conductivity, ≥0.22w/(m.K), with excellent insulation performance.

5.Good corrosion resistance and long service life of more than 30 years.

6.The insulation layer is manufactured in the factory, which can shorten the installation time.

Process Description of FRP Insulation Pipes

FRP insulation pipes have a foam plastic sandwich structure. They are mainly composed of FRP pipes, polyurethane and FRP shells. The greatest advantage of using polyurethane to produce sandwich structures is cold protection, heat insulation, light weight, large bonding area with the shell, uniform load transfer, and good impact resistance, etc.
