Product Description

Model NO.: DN100-500 MPa Classfication: Medium Pressure Piping Standard: ASTM, GB Medium: Liquid Connection Type: Flange Trademark: HYX Specification: DN100-500MM HS Code: 39172900 Temperature Classification: High Temperature Piping Material: FRP Diameter: 100-500 Cross-Section Shape: Round Industry Standard: GB/T 4272-2008 Transport Package: Steel Frame Origin: China For FRP Insulation Pipe, fiber wound FRP Pipe as conveying pipe,the polyurethane, etc materials as central insulation layer, and the fiber wound FRP pipe as the external pressure-bearing protection layer,it is a new type insulation pipe.


Advantages of FRP insulation pipe:

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 for the 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,it can achieve above 30 years.
6.The insulation layer shall be performed in our factory,it can reduce the installation time.

Process description of FRP insulation pipe:

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

Process design:

FRP pipe: according to the medium,concentration,temperature and pressure,to determine the resin,fiber,etc raw material and it's thickness & production process.
Polyurthane material: Adopt the rigid polyurethane foam with low thermal conductivity (0.016~0.08 kcal/m▪h▪ºC),good cold resistant (-45ºC) and convenient fabrication & processing.It's thickness depends on the working condition of the medium and the enviromental condition.The temperature falling of the medium within the range of the design shall be ensured.iFRP 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▪ºC 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.

Process flow:
Prefabrication→assembly→polyurethane foam injection→post treatment→finishing→inspection→storage
