Primary and secondary vacuum facilitiesof up to 10-6 mbar including pumping sets and related networks

* ENGIE Axima personnel is COFREND certified. Recognised since 1978, this certification body has been accredited since 1996 by the French Accreditation Committee (COFRAC) to certify the skills of non-destructive testing technicians. Our technicians are COFREND II LTcertified (leak testing) and COFREND II PT certified (dye penetrant testing).

We offer services covering the complete process• design studies (vacuum, reset to atmospheric pressure, nitrogen buttering),• prefabrication of stainless steel or aluminium alloy networks, • assembly,• instrumentation & control management of the functions, turbo-molecular pumps or cryogenic pumps, sensors and valves,• commissioning,• maintenance/operation.

Leak tests (Cofrend II*) according to different procedures (global helium, spray, pressure variations, etc.).

• Helium leak testing according to standard NF EN 13185 to detect leaks up to a rate of 10-13 Pa.m3/s (10-12 mbar.l/s),• leak testing according to ISO standard 10648-2 for nuclear HVAC glove boxes and duct networks,• leak testing according to Eurovent standard for class B, C and D HVAC duct networks.• dye penetrant inspection of welds.
