Caractériser des produits d'étanchéité

Characterize and qualify sealing materials and components


Sealing materials used in components or pressure equipment (for example, flat joints for flangled joints, braids and packings for valve stems, hydraulic or pneumatic seals, mechanical seals) must be in compliance with regulations related to pressure and tightness
As a manufacturer you have to:
• qualify a component following a standard or specific conditions
• define the application field of a product
• set up a in-lab testing protocol or in-production control protocol
As a user, in order to meet safety requirements, you have to assess sealing performance in close to service conditions (particularly concerning pressure and temperature)


• characterization tests on a large range of parameters (pressure: vacuum - 700 bar for gas / 2000 bar for oil, temperature: cryogenics to 1000°C, leakage measurement: from 1 drop/s to 1 drop in 100 years….). Our experts have a deep knowledge of main customers’ specifications, standards and regulations and can adapt them to any particular procedure. They have a helium and multigas test skill with extended measurement ranges
• testing engineering: we help you define the best lab tightness testing protocol for your company


• an independent laboratory with widely recognized skills in the fields of nuclear energy, petrochemical, aeronautics, cold industry...
• our responsiveness, combined with our extended range of resources make you save development time
