Product information


aquatherm green has not only revolutionised the plastic piping sector, but has been shaping it for decades. Due to its excellent ecological properties, the innovative all-round talent made of corrosion-resistant polypropylene shows its advantages, especially in the field of drinking water applications. It is completely free of heavy metals and toxic chemicals.  aquatherm green is also ideally suited for swimming pools, agriculture, shipbuilding or the transport of potable water, taking into account its chemical resistance. A form-fit and material-fit means a secure connection is created due to the very good welding properties.

Technical details

What should you know about the technical features of AQUATHERM GREEN?

The diameter of the PP pipe determines its location and intended use. In order to be able to lay a pipeline from the connection to the outlet, the pipe diameter of the individual pipes and fittings must be compatible with each other.

aquatherm green S: Ø 20 - 315 mm 

aquatherm green MF: Ø 20 - 32 mm 

aquatherm green MF UV: Ø 20 - 32 mm 

 aquatherm green MF RP: Ø 32 - 315 mm 

aquatherm green MF RP UV: Ø 32 - 315 mm 

The SDR (Standard Dimension Ratio) is a ratio indicating the resistance to pressure. In order to guarantee a certain pressure resistance, a certain maximum SDR number is necessary, depending on the type of material. The following applies: the greater the wall thickness, the smaller the SDR number and the more pressure-resistant the plastic pipe. The unit indicates the ratio between outer diameter and wall thickness of a pipe. aquatherm blue is available in the following SDR sizes:

SDR 6: aquatherm green S

SDR 7,4: aquatherm green S | aquatherm green MF | aquatherm green MF UV

SDR 9: aquatherm green MF RP | aquatherm green MF RP UV

SDR 11: aquatherm green S

aquatherm polypropylene pipe systems put an end to corrosion damages. All materials are corrosion resistant and show reduced flow noise compared to metallic pipes. aquatherm pipes are impermeable to light. Therefore there is no danger of algae formation.

The systems include all elements for the pipe system installation for chilled, hot fluid and various industrial applications:
• Pipes in straight lengths and / or coils
• Fittings
• Flanged joints
• Water point connections and accessories
• Welding devices and machines
• Weld-in saddles
• Manifolds
• Shut-off devices
• Cutting and peeling tools
• Installation guide and fastenings
• Transition joints from PP to metal or from metal to PP


How can AQUATHERM GREEN be processed?

aquatherm pipes and fittings are connected by heat fusion, which creates a homogeneous, cohesive unit with no leak paths. Heat fusion connections are stronger than the pipe itself, providing lasting safety at these critical points of a piping system. A properly executed aquatherm fusion creates a permanent leakproof connection.

What fire protection solutions are offered for aquatherm green?

The aquatherm polypropylene pipe systems comply with the requirements of the fire classification B2 DIN 4102 (normal inflammable). Compared to natural products like wood, cork or wool, aquatherm polypropylene pipes do not produce any gas toxicity. In case of fire, there is no risk of dioxin emissions.

To avoid fire and smoke transmission aquatherm advises the use of fire retardant seals. The fire resistance period is the minimum period in minutes. The extent of the preventive measures depends on the type of installation. The determining of fire areas and fire classification has to be made in accordance with the law of the country. Information is given by the Planning Department and Building Control Office or the Fire Protection Representative.

Basically fire walls and ceilings with pipe passages have to be installed to the same fire resistance classification. All fire protection systems with a corresponding classification are suitable for aquatherm polypropylene pipes.

aquatherm polypropylene pipes may be stored outside at any temperature. A solid base for the pipe is very important to avoid a deformation of the pipes while in transport and storage.
At temperatures below 0 °C it is possible to damage the pipes through strong impacts. The material has to be treated with caution at low temperatures. In spite of its high resistance aquatherm pipes should be treated with care. UV-radiation has effects on all high polymer plastics. Do not store permanently outdoor. The maximum permissible storage time outdoors is 6 months.
