Our ambition
The challenges that we take on every day push away the boundaries of technology.
The level of performance to be achieved is increasingly demanding. The objectives of end users are to reach extremely low leakage rates of around 10⁻¹² to 10⁻¹¹ mbar.l.s⁻¹ corresponding to the volume of a pinhead, which would take 200 or even 2000 years to leak out!
The challenges faced are linked to increasingly difficult operating conditions, which can combine different constraints, such as high pressure and temperature, complex mechanical stresses, interactions between materials and in relation to fluids, bacterial aggressiveness.
This is the case, for example, with energy technologies, both in the nuclear field and that of alternative energies.
