Some advantages of the aquatherm blue pipe MF system are:

  • Corrosion resistant (internal and external)
  • Low pipe roughness of 0.0070mm (less friction head loss; smaller pumps)
  • Low Thermal Conductivity
    (λ  = 0.15 W/mK; λ Copper = 350-384 W/mK, λ Carbon Steel = 50 W/mK)

  • Recyclable
  • Light in weight (ρ < 1)
  • Less linear expansion (α = 0.035 mm/mK);


Provision for linear expansion aquatherm MF pipes vs Copper pipes 

  • no thrust blocks required for in ground application
  • Larger support intervals
  • Very good sound insulating characteristics
  • Very good chemical resistance
  • High impact strength
  • Easy processing
  • Excellent material for prefabrication

Weld in Saddle Technique

UV Resistance

Pipes and fittings made from fusiolen PP-R or fusiolen PP-R C are normally not installed where subject to UV-radiation.

All aquatherm PP-R pipes and fittings have UV stabilizer to bridge transport and installation times. Maximum storage time in the open air is 3 months under Australian UV-conditions.

For the application in open air aquatherm offers composite pipes with an UV-protective layer made from black polyethylene, which excludes damages caused by sunlight.

Aquatherm PP-R fittings have to be protected against sunlight by using a black UV-resistant adhesive tape.

Painting the aquatherm PP-R pipes and fittings with an UV resistant epoxy based primer or lagging the aquatherm PP-R pipes and fittings with an UV resistant insulation is sufficient as well to protect the PP-R pipe system from UV damage.

Available types of pipe:

  • aquatherm green pipe MF UV
  • aquatherm blue pipe MF UV (on demand)
  • aquatherm blue pipe MF UV-OT (on demand)

Peeling of the UV layer

When welding UV pipe peel off the UV layer off the aquatherm pipe before fusion.

Push the end of the UV pipe into the guide of the peeling tool. Peel off the UV layer up to the top of the peeling tool. It is not necessary to mark the welding depth as the back stop of the peeling tool indicates the correct welding depth.

Before starting the fusion, check if the UV layer has been completely removed.

Pipe system for potable water, heating and climate technology

Industrial pipes

In the field of plastic pipes for industrial application with the aquatherm green pipe and aquatherm blue pipe (climatherm) systems aquatherm offers a high-quality, sophisticated and well-approved system for the transport of liquids and further media. Due to its chemical resistance it is most suitable for the transport of aggressive liquids like acids, bases and liquors. Pharmaceutical-, chemical- and food industry as well as water industry trust in our long lasting and worldwide experience as manufacturer of plastic pipe systems.

For the supply with potable water and liquid food in hotels, stadiums, universities, infrastructural large plants or other major projects the aquatherm green pipe system is most suitable due to its excellent hygienic and ecologic features and its neutrality of smell and taste.

Also best suited is aquatherm blue pipe system (climatherm) for the application in heating and climate technology. 

Whether in manifold construction as risers or distribution pipes or for the transport of various media on longer distances, e.g. for district heating, the climatherm pipe system now provides a wider field of applications.
