HV microhardness measuring equipment

Valve stem sealing test bench

Bolted joint assembly with internal heating (900°C)

Fatigue test bench for cylinder head gaskets (250 bar / 200Hz)

High pressure water test bench

Endurance test bench for valves

 The laboratory is equipped with a variety of furnaces and ovens :

5 large ovens of 1,5 to 3m cube up to 600°C

3 big furnaces (125L) for high temperature up to 1200°C

Numerous ovens of smaller dimensions

Specific mock-ups designed to be tested in these ovens can allow :

Simulation of radial motion due to differential expansion

Accelerated ageing (up to 75 000 hours) of metallic seals

Simulation of nuclear pool gate seal operation

Test of sealing solutions for high temperature electrolysis (HTE)

Characterization of air lock door sealing

Characterization of aircraft engine sealing

Characterization of autoclave sealing
