The Chemistry and Corrosion Laboratories provide equipment which contributes to the fundamental understanding of chemically induced ageing mechanisms and therefore to safety, availability, radioprotection, and environmental impacts. There are several experimental loops to study corrosion under primary and secondary circuit conditions as well as many commonly used chemical analysis apparatus (e.g. ICP-AES, ICP-MS, CPL, etc.) and around 60 autoclaves. The Mechanical Laboratories provide experimental tools and analysis to study components and material integrity, mechanical degradation, fatigue and creep. Specific constitutive laws of materials are established to feed numerical models to simulate micro-mechanical behavior at the crystalline scale.
The corrosion loop present on Axel’One makes it possible to reproduce various industrial conditions with the possibility of working at high pressure (up to 200bar), high temperature (up to 350°C), under flow and the presence of different online analysis solutions. The loop makes it possible to deal with the problems of corrosion and damage encountered in many energy-related environments: capture, transport, storage and recovery of CO2, geothermal energy, oil and gas production, etc. Environments increased in acid gas pressure (CO2, H2S) and temperatures constitutes significant challenges for the steel resistance, which can be subjected to corrosion on one hand and to environmental-assisted cracking (hydrogen embrittlement and / or stress corrosion) on the other hand.

Syngaz
Top Industrie worked with MTS as an individualized supplier for its new product line of Gas corrosion test machines (GCTM) suited to the needs of growing laboratories, interested in gas behavior in the new energy services segment, for the complete chain of production, storage and transport.
We can offer a wide range of versatile autoclaves, well adapted with required force loading, and integrating fixing devices for all standardized or typical specimens.
Our loading line is auto compensated for pressure force induced. An internal force sensor allows the real loading force to be known, without taking in consideration the friction coefficient or pressure effects.
Recirculating or multiphase Test Loop
- Recirculation loops provide several benefits:
- Recirculating water flow maintains the test environment around the specimen
- Dissolved corrosion products do not affect the chemistry of the test environment because of the large water volume
- Test water can be purified in an ion exchanger and active carbon filter
- The dissolved gas concentration can be maintained in the storage tank
- Water chemistry can be monitored and controlled on-line by H2, O2, pH, conductivity analyzers
Loop media:
