No chance for corrosion

Smooth operation over many decades: this is a simply formulated, although not always easy to implement, wish in the field of heating, ventilation and air conditioning technology. Steel pipes used in air conditioning systems, for example, are particularly susceptible to corrosion on the outside of the pipe. Condensation that forms between the insulation and the pipe attacks the pipe surface and breaks it down. Corrosion inside pipes is a major problem in heating systems: it leads to pressure losses and increased energy consumption by the pumps used.

With aquatherm blue pipe corrosion damages are a thing of the past, because it consists of the 100 % corrosion resistant material polypropylene. This considerably extends the service life of the air conditioning or heating system.

Due to its heat and sound insulating properties, aquatherm blue pipe requires significantly less insulation against heat and cold loss or condensation when falling below the dew point compared to metallic pipes and is therefore ideal for heating and cooling systems from commercial buildings to detached houses. Its light weight also facilitates installation and brings significant time benefits.

Product advantages

aquatherm blue pipe


  • high temperature-resistance
  • high compressive strength
  • absolutely corrosion resistant
  • Resistance to chemicals
  • lower weight than metallic materials
  • thinner insulation required compared to metallic pipes


aquatherm pipes and fittings are connected by welding. In the process, the plastic fuses into a homogeneous, cohesive unit. Double material thickness at the connection point – this means double safety at the otherwise critical point of a piping system. With the fusion technique of aquatherm you quickly create a permanently tight connection!

Depending on the dimension, pipes and fittings are joined by the heating element socket welding process, the butt welding process or the electro socket welding process.
