Specifications

   FRP heat insulation pipe is a kind ofnew heat preservation pipe, which is made of fibr wrapped glass fiber reinforced plastic pipe,which is made of polyurethane and other materials as intermediate insulation layer.
1.Characteristics of FRP heat preservation tube
  (1)Light weight and high strength, transportation, installation and maintenance is convenient, no heavy lifting equipment.
  (2)Excellent hydraulic characteristics, smooth inner wall, small fluid resistance, can save pumping costs.
  (3)The inner wall of the pipeline is not dirty, and the inner wall of the pipe is smooth.
  (4)Low thermal conductivity, 0.39w/m.k, excellent thermal insulation performance.
  (5)Good corrosion resistance, long service life, up to 30 years.
  (6)The insulation layer is made in the factory, which can shorten the installation time.
2.FRP insulation pipe technology
  FRP thermal insulationpipe for foam sandwich structure. Mainly composed of FRP pipe, polyurethane sandwich structure is cold, heat insulayion, light weight, bonding with the
 housing area is large,can evenly transfer load, anti impact performance.
3.Technological process
   Prefabricated FRP pipe-----Prefabricated FRP shell----Shell and pipe assembly-----Overall injection of polyurethane foam postprocessing-----finishing-----test-----be put in storage
4.FRP insulation pipe application
  FRP heat insulation pipe is used in hot spring water transporation, oil field geothermal fluid transportation pipe, city and factory heating system, and other heat transfer pipe and so on.
