Sprinkler Pipe System




Corrosion in fire extinguishing systems brings the risk that the sprinkler system may fail when it is needed most. Leaks at the joints increase installation and maintenance costs.
The aquatherm red pipe system (former: Firestop pipe system) developed by aquatherm prevents both and offers a high level of security due to its flame resistant properties.

The lower the SDR the higher the pressure rating

Material: PP-R FS (MF; faser composite technology)
not easily flammable acc. to DIN 4102-1, building material class B1
Pressure rating: PN 20 (SDR7.4 MF)
160mm x 7.1 (SDR11 MF)
Packing unit: straight lengths á 6 m
Colour: red/4 green stripes

aquatherm red pipe complies with AS4118.2.1-1995

Aquatherm red pipe in future with red inner layer

The colour of the inner layer of the aquatherm red pipes is changed in the future from the current white to red. This change, caused by production technique, was made mid May 2013.

Since this is only a change of colour with no effect on the technical properties of the pipe, the colour change does not affect the approvals of the pipe.

During a transition period both colour versions are supplied.
