Diaphgram tank

The volume of the water in a pipe system will vary depending upon its temperature. An expansion tank is used to ensure the absorption of excessive volumes of water.

The volume of the water in a pipe system will vary depending upon its temperature. An expansion tank is used to ensure the absorption of excessive volumes of water. This normally consists of a closed tank, where a flexible membrane absorbs the excess pressure.
The gas-filled side of the tank contains nitrogen. Its preset pressure must correspond to at least the static pressure plus 0.5 bar. Breaks or explosion of the pipe work due to excessive pressure can occur if a diaphragm tank is not included.
