		HVAC: expansion

Selection of compensators HVAC, for thermal expansion at medium temperature over 100°C
General:
In the building industry pipelines for e.g. water, superheated water and steam are used with constantly
changing medium temperatures.
Temperatures of 110°C for superheated water and 180°C for steam are known values.
Whilst the mounting temperature during winter can go as low as 5°C.
In this way a temperature difference in a pipeline up to e.g. 175°C can occur.
Because of the difference in temperature the metal pipe will elongate and shrink resulting
in 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!
