Pressure / Temperature Diagram

Temperature/Pressure Graph: How to find the right tube system

Material, operating temperature and pressure are decisive for the selection of the right tube system. This calculation tool helps you to correctly combine the parameters and to find the optimal system. 

  • First, select the application: water, gas or industry, or other medium. 
  • Next, enter your units for temperature and pressure (°C and bar or °F and psi) and the desired material. You can either establish or remove the dependency between pressure and temperature value.
  • Then, enter the temperature of the medium, the working pressure and the desired service life.

As a result, the design factor for the material is shown in the parameters and in the graph you’ll see an overview of the temperature and pressure up to which the selected material can be used as well as your own input for comparison.

If you have selected several materials, you can also display the pressure/temperature curve individually by clicking on the respective material below the graph. You can then print out the results or send them by e-mail.
