Pre-insolated aquatherm Faser composite pipes

for district heating and cooling

one of the most energy-efficient methods for transporting heating or cooling over long distances is by the use of buried piping. To achive the necessary insulating characteristics needed for this application, aquatherm offers factory pre-insulated Fusiotherm® ISO and climatherm OT ISO for drinking water and heating/cooling networks, with operating pressures up to 20 bar (290 psi) and operating temperatures up to 90° C (190° F).

The aquatherm pipe systems are factory-made pre-insulated. They are available in the dimensions 32-315mm:

- Fusiotherm® ISO-fasercomposite pipe system SDR 7,4

- climatherm OT ISO-fasercomposite pipe system SDR 11

These systems are insulated with closed cell PUR rigid foam and coated with a casing pipe made of HDPE.

Fields of application 

  • construction of heating systems
  • climate and chilled water technology
  • potable water supply
  • process water plants
  • industrial water supply

 Components

The following components are available for all insulated fasercomposite pipe systems:

  • pipes (6 m and 12 m straight lengths)
  • elbows 45 °
  • elbows 90 ° (short and long design)
  • branches
  • reducing branches
  • cross over branches
  • accessories for field-insulating of joints
  • special fittings on request

Connection

aquatherm faser composite pipes are joined by socket-welding in the dimensions 32 – 125 mm, and butt-welding in the dimensions 160 – 315 mm.  

The heat fusion welding process for joining the pipes and fittings creates a homogeneous, permanent, and leak-free joint. The aquatherm fusion equipment makes the joining process quick and easy, with joints ready for full pressure testing in a matter of minutes. 

More detailed information and instructions on the welding process and equipment are available in our technical catalog E10101. 

Accessories and materials are available for professional insulation of the joints at the job site.
