HL 101 Thermal Expansion Training Panel Show data sheet (pdf file) Print page
Technical Description

The trainer comprises original components as used in heating and sanitation systems and is therefore relevant in practice.

  There are six expansion sections. One of the sections is fitted with a compensator. The elongation of the pipes is indicated on dial gauges. A force measuring device enables the expansion force to be determined.

Learning Objectives / Experiments
- Thermal expansion of different materials such as 
  PVC, PE, copper and steel
- Determination of thermal expansion coefficients
  and the expansion force
- Measurement of pipe elongation
- Effect of varying pipe diameter
- Expansion compensator

* Thermal expansion of different pipe sections1
* Pipe sections can be individually selected using 

  ball valves1
* Water connections made using quick-release
