Geothermal Water Heating Pipe Systems from Aquatherm

Geothermal Water Heating Pipe Systems from Aquatherm

The aquatherm green pipe SDR9 MF RP and aquatherm blue pipe SDR11 MF RP for geothermal heating water projects.

Aquatherm can supply polymer pipe systems for (in ground) geothermal heating water applications. For this type of application the (in ground) pipe system has to meet the following conditions.

The challenge:

  • The pipe material has to be suitable for in ground geothermal heating, conveying geothermal heating water up to 65-70°C (max.), a water pressure up to 1,000kPa (10 bar), and with a calculated design life of 50 years.
  • Non-corroding (internal and external) and durable pipe material.
  • The pipe material has to be chemically resistant against the various minerals in the geothermal bore water.
  • Good insulation features (low thermal conductivity); pre-insulated, only if needed.
  • Pipes sizes required are up to DN300.
  • The pipe had to be somewhat flexible.
  • Easy and proven jointing method.

Advantages:

  1. The aquatherm green pipes SDR9 MF RP and aquatherm blue pipes SDR11 MF RP are made of a corrosion resistant material, being PP-R (Polypropylene Random Copolymer).
    This eliminates future internal or external corrosion issues and provides longevity.
  2. Less pipe roughness = 0.0070mm (less friction head loss; smaller pumps).
  3. Recyclable material.
  4. Light in weight (density = 1,000kg/m3); 8x lighter than steel, 9x lighter than copper. This might save hiring a crane to lift the pipes.
  5. Aquatherm manufactures its own glass-fibre reinforced polypropylene composite.
    Our three-layer pipes are extruded with a fibre-reinforced middle layer that strengthens the pipe and restricts expansion and contraction. Linear expansion coefficient (α = 0.035mm/mK).
  6. Since the thermal expansion forces [kN] of the aquatherm green pipes SDR9 MF RP and aquatherm blue pipes SDR11 MF RP are less than for metal pipes, for in ground pipework, no thrust blocks are required.
  7. Very good chemical resistance.
  8. High impact strength and ring stiffness.
  9. Easy processing (socket fusion and butt welding).
  10. The aquatherm green pipes SDR9 MF RP are available up to ø355 (OD) (DN300) and the aquatherm blue pipes SDR11 MF RP are available up to ø450 (OD) (DN400).
  11. Both aquatherm pipe systems can also be supplied in a pre-insulated version up to ø355 (OD) (DN300), called aquatherm TI (Thermal Insulated).
