		potable water: expansion

Selection of compensators for potable water, for thermal expansion at medium temperature under 100°C
General:
In potable water installations many pipelines with varying medium temperatures are being used.
Temperature ranges 5 to 25°C for cold water and 65 to 80°C for hot water.
And the installation temperature during winter can go as low as 5°C. This way a temperature
difference in the metal of the pipeline in installations can easily go up to 75°C.
Because of the temperature differences the pipe will elongate and shrink giving length variations.
One of the possibilities to compensate for these changes is to install compensators
also called expansion joints.
One will find these expansion joints in pipelines in shafts, walkways, corridors and basements.
Solution with axial compensators:
During the design of the installation as well as during the mounting of pipelines, brackets and sliding and
fixed points, forces due to pressure thrust and springrates come into play.
Especially when using axial expansion joints considerable forces will act on fixed points and
bracketry when the pipeline is put on pressure.
Solution with lateral / angular compensators:
To reduce the influence of pressure thrust tied lateral or angular compensators can be used,
however pipeline configuration is to be examined closely. Consult us for advise!
