Challenge

  • Determine the source of piping vibrations
  • Apply effective modifications to reduce them below the recommended values

Solution

  • Identification of a source of flow induced vibrations in a Tee junction
  • Flow modelling to characterize the source of vibrations and the pulsation phenomenon
  • Piping FEM modelling to determine mechanical natural frequencies
  • Multiple solutions identified to find the best compromise between vibration reduction and cost of modifications
