Product information

What can AQUATHERM BLUE do?

aquatherm blue made of corrosion-resistant polypropylene (PP) is the specialist for the transport of cooling and heating media in closed systems and is therefore particularly suitable for various industrial applications. The physical properties of the plastic are tailored to the special needs of the heating and cooling sector.

The material is characterised by high temperature and pressure resistance. Thanks to its exceptionally good welding properties, the pipe and fitting fuse to form a homogeneous, materially bonded unit. This results in maximum safety and service life. In combination with the extensive range of fittings, the system includes all components for the pipe performance installation of air conditioning and heating systems as well as for plant engineering.

AQUATHERM BLUE S

Single-layer pipes are particularly suitable for use in installations with a medium temperature of up to 25°C.

AQUATHERM BLUE MF

is a multi-layer and fiber-reinforced composite pipe.

The composite pipes produced in the multi-layer extrusion process receive increased stability due to the fiber filling introduced in the middle layer. 

Numerous other advantages result from this technology:

  • the linear expansion is reduced by 75% compared to conventional PP pipes
  • the flow rate is increased by 20% at the same pressure ratios due to lower wall thicknesses
  • high stability
  • the linear expansion coefficient is almost identical to that of metallic pipes ensuring span distances can be increased and fixing clamps can be saved compared to all-plastic pipes
  • lighter in weight
  • high impact strength
  • simply cut and weld

AQUATHERM BLUE RP 

has an increased compressive strength.

AQUATHERM BLUE UV

Fusiolen® pipes are normally not exposed to the effects of UV rays when installed. 

To bridge the transport and assembly time, aquatherm polypropylene pipes and fittings are packaged UV-protected. The maximum outdoor storage time is 6 months.

For outdoor pipe installation, aquatherm offers polypropylene composite pipes with a UV layer of polyethylene. Damaging influences caused by the sun's rays are then excluded.

Technical details

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

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 blue S: Ø 20-32 mm

aquatherm blue MF: Ø 20-25 mm

aquatherm blue MF UV: Ø 20- 25 mm

aquatherm blue MF OT: Ø 20- 25 mm

aquatherm blue MF RP: Ø 32 - 630 mm

aquatherm blue MF RP UV: Ø 32 - 630 mm

aquatherm blue MF RP OT: Ø 20 - 250 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 7.4: aquatherm blue S | aquatherm blue MF | aquatherm blue MF UV | aquatherm blue MF OT

SDR 9: aquatherm blue MF RP | aquatherm blue MF RP UV | aquatherm blue MF RP OT

SDR 11: aquatherm blue S | aquatherm blue MF RP | aquatherm MF RP UV | aquatherm MF RP OT

SDR 17.6: aquatherm blue MF RP | aquatherm blue MF RP UV

aquatherm blue is made of corrosion-resistant material. This considerably extends the service life of the pipeline, for example for an air conditioning system. The material of aquatherm is characterized among other things by its special high heat and extraction stability. The physical and chemical properties are adapted to the special needs of the heating and cooling sector. Due to the exceptionally good welding properties, pipe and fitting fuse to form a homogeneous, materially bonded unit; this has made the material fusiolen® famous worldwide.

In combination with the aquatherm fittings, the system provides all components required for the piping installation of air conditioning, refrigeration, heating systems, and industrial applications:

• Pipes in straight lengths and/or coils
• Fittings
• Flanged joints
• Water point connections and accessories
• Welding devices and machines
• Weld-in and weld-on saddles
• Manifolds
• Shut-off devices
• Installation guide and fastenings
• Transition joints from polypropylene to metal, or from metal to polypropylene

When integrating aquatherm piping systems with other systems or components not made of polypropylene (e.g. valves, pumps, other piping, check valves, strainers, etc), care must be taken to ensure the operating parameters for polypropylene won’t damage the other materials or vice versa. Be aware that even if the aquatherm pipe is compatible with the fluid being transported, other materials in the system may not be. All parts of the system must be verified as compatible with the medium being carried before installing them. And, while the aquatherm pipe does not require treatment to protect it from corrosion, metals (ferrous and non-ferrous) in the system may be susceptible to corrosion. Do not mix the aquatherm pipe with other piping systems in conditions that will cause the other system or components to fail.

To the contact

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. Inspite 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.
