Ensure a strict separation of the high-pressure pipes
towards the rest fo the building. Especially with wall
penetrations there is a risk that there is a contact be-
tween the high-pressure line and the brickwork. The
resulting vibrations can lead to a high level of sound
pollution throughout the entire building (solid-borne
sound).
In case of a change in temperature the built in mate-
rial expands or contracts. As the piping systems are
inflexible, these temperature-related changes must
be considered during planning. For this reason, flexi-
ble expansion joints or expansion elbows are
used with elbow. This is necessary with a line length
of more than 50 m. The place for a piping anchorage
must be selected carefully.

For financial reasons the so-called expansion el-
bows are usually installed:
A- expansion elbow
B- expansion elbow with flexible hose
1- fixed points
