Our full range of expertise to help you quickly and accurately identify the causes of leaks


Further to the failure of an item of your fluid equipment wherein tightness is a critical parameter, you want to:

  • Identify and analyse the root causes of leakage
  • Check the conformity of sealing materials with respect to the specific characteristics of reference materials
  • Understand and address the damage mechanisms
  • Find long-term solutions
  • Meet the requirements of the energy and ecological transition

Provide and conduct a comprehensive analysis (on a case-by-case basis) from all the observations and parameters associated with the failure:

  • On-site assessment: detection, location and quantification of leaks
  • Mechanical analyses
  • Physical and chemical analyses of polymer, elastomer or metallic materials
  • Tests under conditions similar to service conditions (pressure, temperature, fluid, etc.).
  • Assistance with selecting alternative sealing solutions
  • Our experience and knowledge of sealing products and their behaviour stem from the large number of tests performed
  • An overall approach with comprehensive analysis equipment (tightness, mechanical and physical-chemical)
  • Objectivity of the analysis, conducted by a neutral and independent institut
  • Provision of additional expertise: Assembly, NDT, metrology, etc.
  • Cetim is the French leading specialist in failure analysis and will provide you with neutral and reliable results for use in insurance or judicial appraisals, or for industrial purposes
  • Cofrend-certified operators (levels 2 and 3)
