Thermal expansion definition

Thermal expansion means the pressure increase due to a rise in water temperature that occurs in water piping systems when such systems become "closed" by the installation of a backflow prevention assembly or other means, and will not allow for expansion beyond that point of installation.
Thermal expansion means the pressure created by the expansion of heated water.
Thermal expansion means volumetric increase of water due to heating resulting in increased pressure in a closed system.

Examples of Thermal expansion in a sentence

  • Thermal expansion can also cause intermittent temperature-pressure relief valve operation: water discharged from the valve due to excessive pressure build up.

  • Thermal expansion in bridge expansion joints and paved surfacesiii.

  • Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve, and possibly the heater itself.

  • Thermal expansion of the pipe shall be accommodated in the joint.

  • Thermal expansion: 1.670 x 10-5 in/in/deg F, tested to ASTM C531.
