FRP insulation pipe

Introduction:
FRP insulation pipe is filament winded by fiberglass roving, used as conveying pipe. It is a new type insulation pipe which produced by the polyurethane material as central insulator layer and FRP pipes as the external pressure-bearing protection layer.

Characteristics:

1.        Light weight, high strength, convenient transportation, installation and maintenance, the heavy lifting equipment is not required

2.        Good water conveying, smooth inner surface, small resistance for fluid can save the cost of pumping.

3.        No fouling on the inner surface, through long-time use, the smooth inner surface also can be kept.

4.        Low thermal conductivity, it is 0.39w/m•k，excellent insulation.

5.        Good corrosion resistant, long service life.

6.        The insulation layer shall be performed in factory, and it can reduce the installation time.

FRP insulation pipe is foam interlayer structure; it is mainly composed of FRP pipe, polyurethane and FRP outer protection pipe. The excellent advantage for the polyurethane interlayer are cold resistant, heat insulation, light weight, big adhesive area with the outer protection pipe, uniform load transferring, good impact resistant, etc.

1.        FRP pipe：According to the medium, concentration, temperature and pressure, to determine the resin, fiber, etc raw material and its thickness & production process.

2.        Polyurethane material: Adopt the rigid polyurethane foam with low thermal conductivity, good cold resistant and convenient fabrication & processing. Its thickness is according to 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.

3.        FRP outer protection pipe: It mainly plays the role of protecting the polyurethane, it also has low thermal conductivity, in addition, it undertakes the external load, and be added UV absorber & aging resistant agent, to extend the service life of the FRP insulation pipe.

Application: FRP insulation pipe can be used fro hot spring water conveying, oilfield geothermic fluid conveying, heat supply system of city & and factory, and other hot medium conveying, etc.
