Filament winding FRP theramal insulation pipe with Lianzhong brand is a kind of new theramal insulation composite pipe which taking the filament winding FRP pipe as its inner duct, polyurethane foam as its middle thermal 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 thermal insulation pipe,the product possess the following advantages:

1.Lightness and high strength ,easy to convey, 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 thermal insulation with the temperature lowers than 0.50°C/km.

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

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

1. Specification:

Diameter:DN25-2000mm

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

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

The thermal insulation layer's thickness can be designed according to customer's requires to define the OD.

Pipe wall thickness and unit weight of FRP pipe under different pressure.

2. 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.

 3.Application

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

in urban and factory.

Lightness and high strength Excellent properties of corrosion resistance FRP pipe
