FRP/GRP Insulation Pipe
The FRP/GRP insulation pipe is a lightweight, high-strength, and corrosion-resistant non-metallic pipe designed for efficient thermal insulation. This innovative pipe features a fiber-wound FRP (Fiber Reinforced Polymer) pipe as the core conveying pipe, with a polyurethane or other insulating material as the central layer, and an external FRP layer providing added strength and protection against external pressure.
Product Introduction
The FRP/GRP Insulation Pipe is a lightweight, high-strength, and corrosion-resistant non-metallic pipe designed for efficient thermal insulation. This innovative pipe features a fiber-wound FRP (Fiber Reinforced Polymer) pipe as the core conveying pipe, with a polyurethane or other insulating material as the central layer, and an external FRP layer providing added strength and protection against external pressure.
Ideal for transporting hot or cold fluids, the FRP insulation pipe offers excellent thermal performance, corrosion resistance, and durability. It provides reliable protection against heat loss, ensuring energy efficiency and longevity in various industrial applications, even in harsh environments.

Process design
FRP pipe: according to the medium, concentration, temperature and pressure, to determine the resin, fiber, etc ray material and it’s thickness & production process.
Polyurethane material: Adopt the rigid polyurethane foam with low thermal conductivity (0.016～0.08kcalm•h•℃) good cold resistant(- 45℃) and fabrication & processing. It’s thickness depends on the working condition of the medium and the environmental condition. The temperature falling of the medium within the range of the design shall be ensured.
FRP outer protection pipe: it mainly plays the role of protecting the polyurethane, it also has low thermal conductivity, equals to 1/100～1/1000 of the metal’s, it is 0.34 kcal/m•h•℃ approximately, in addition, it undertakes the external load, and be added UV absorber & ageing resistant agent, to extend the service life of the FRP insulation pipe.
