Diaphragm expansion tank

Temperature in degrees Fahrenheit and pressure in psig

  • initial temperature 50oF
  • initial pressure 10 psig
  • maximum operating pressure 30 psig
  • safety factor aprox. 2
  • acceptance factor aprox. 0.5

The diagram below can be used to estimate the tank volume and acceptance volume of a diaphragm expansion tank at low temperatures.

Temperature in degrees Celsius- pressure in kPa

  • initial temperature 10oC
  • initial pressure 70 kPa
  • maximum operating pressure 200 kPa
  • safety factor aprox. 2
  • acceptance factor aprox. 0.5

The diagram below can be used to estimate the tank volume and acceptance volume of a closed expansion tank at low temperatures.
