Material Qualification

OEO test a wide range of materials for compatibility with our subsea and topside fluids, both during development and subsequently on the materials later found to be present in systems as part of later mapping processes.


The Manchester Facility is registered to ISO9001:2015 and all testing conducted on site closely follows the API 17F specification wherever practical.


Typical testing on metals involves a 12 week soak test at 70 °C with regular checks at 3, 6 and at the final 12 week result.


Typical testing on elastomers involves a 3 month soak test at 70 °C with regular checks at 1 week, 1 month and at the final 3 month result.


In addition, we are able to adjust the testing procedure to varying durations and temperatures in line with customer requirements.
