FRP THERMAL INSULATION PIPE

Filament winding FRP theramal insulation pipe with Lianzhong brand is a kind of new theramal insulationcomosite pipe which taking the filament winding FRP pipe as its inner duct,polyurethane foam as itsmiddle theramal insulation layer and the winding FRP pipe as its protective layer which against the outerpressure.The products is the self-developed and researched result which complied with the need of presentmarket and combined the experience of the composite's professional development and production in 10 yearsby the technique center of Lianzhong Group.Compared with the traditional theramal insulation pipe,the productpossess 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:DN25-2000mmLength:1m,3m,6m,12mPressure classes:0.1Mpa,0.6Mpa,1.0Mpa,1.6Mpa,2.5MpaThe theramal insulation layer's thickness can be designed according to customer's requires to definethe OD.Pipe wall thichness and unit weight of FRP pipe under different pressue.Primary shaped techniquesControlled by the computer and with the technics of filament winding,the inner and outer of FRP pipe takesoverall-frothed polyammoniaester as its interlayer between the inner and outer layer.ApplicationApplication widely in thermal spring,conveyance of heat liquid of water-oil field and collective heat supplyin urban and factory.
