Detailed Product Description

Filament winding FRP theramal insulation pipe with Lianzhong brand is a kind of new theramal insulation

comosite pipe which taking the filament winding FRP pipe as its inner duct,polyurethane foam as its

middle theramal insulation layer and the winding FRP pipe as its protective layer which against the outer

pressure.The products is the self-developed and researched result which complied with the need of present

market and combined the experience of the composite's professional development and production in 10 years

by the technique center of Lianzhong Group.Compared with the traditional theramal insulation pipe,the product

possess the following advantages:

1.Lightness and high strength,easy to conveying,installation and maintenance without the giant hanging

   equipment.

2.Excellent hydraulic property,smooth inner wall,low resistance against the liquid and saving the cost of

   pump-transporting.

3.Even long-used the inner wall is always smooth without filth.

4.Low thermal conductivity as 0.28 w/k and distinguished property of theramal insulation with the temperature

   lowers than 0.50C/km.

5.Execellent properties of corrosion resistance and long life usage of more than 30 years.

6.The theramal insulation layer is made in factory thus the time of installation be shored.

Specification:

Diameter:DN25-2000mm

Length:1m,3m,6m,12m

Pressure classes:0.1Mpa,0.6Mpa,1.0Mpa,1.6Mpa,2.5Mpa

The theramal insulation layer's thickness can be designed according to customer's requires to define

the OD.

Pipe wall thichness and unit weight of FRP pipe under different pressue.

Primary shaped techniques

Controlled by the computer and with the technics of filament winding,the inner and outer of FRP pipe takes

overall-frothed polyammoniaester as its interlayer between the inner and outer layer.

Application

Application widely in thermal spring,conveyance of heat liquid of water-oil field and collective heat supply

in urban and factory.
