Cetim Engineering

Your expectations

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

Our solutions

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

Your benefits

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)

Case studies

Mechanical components Energy Equipments

Techmaflex

To understand the root causes of a sudden degradation of leak tightness, Techmaflex decided to have its seals thoroughly analysed through modelling and simulation. The result? A change of materials and suppliers!

Transport Equipments

Tisseo

As part of the overhaul of its trains, the company operating the Toulouse metro system entrusted Cetim with analysing and testing the hoses which the braking systems are equipped with. Conclusion : these hoses are in good condition and their operation can continue.

Veolia

Veolia adds another string to its bow and qualifies the leak tightness of the pipe fittings it uses on the pressure drinking water networks it manages.
This qualification relies on tests entrusted to Cetim teams.

Energy

EDF

Do PTFE sealing braids retain their sealing performance once irradiated? Cycling tests carried out on an instrumented test bench specifically designed to meet EDF’s requirements gave an affirmative answer to this question.
