Element can perform exposure testing of elastomers, thermoplastics, and composites in sweet (i.e., non-sour) fluids to provide an insight into how they degrade in a variety of both liquid and gaseous environments. Our tests are carried out in accordance with NORSOK, ISO, API, ASTM and NACE standards, as well as to custom procedures from clients, or developed for clients.
Element has a long track record of supporting Oil and Gas customers with evaluating the compatibility and durability of polymers and composites for upstream, midstream and downstream applications.
We have over 30 years of experience of delivering test programmes to the NORSOK M-710 and ISO 23936 standards; these focus specifically on sealing material durability and Rapid Gas Decompression (RGD) resistance of elastomeric materials. We have also for many years tested sealing materials to API 6A Annex F.1.11 and F.1.13 protocols. Our industry-leading specialists have made significant contributions to both standards and are members of the ISO standards Working Group committee.
We utilize our state-of-the-art HTHP laboratories to simulate hazardous in-service environments and expose different types of polymeric materials and components to brines, oils, treatment chemicals and gases. The fluids can be single or multi-phase, and test duration ranges from short-term (e.g., a standard RGD test of 8 days) to long-term (e.g., one-year exposure of insulation materials according to ISO 12736).
With one of the most comprehensive ranges of materials testing services in the sector, we can track material performance over time by quantifying changes in its physical and mechanical properties.

Assessment of the thermal, physical and mechanical performance of thermal insulation coating materials on pipes, field joints, and components
Element uses a fully instrumented 0.8 m diameter SST (Simulated Service Test) vessel for two 5 m insulated pipes capable of being heated to 200°C internally with up to 250 bar external water pressure at 4°C for tests lasting up to 12 months. Our Engaged Experts can thoroughly assess subsea wet insulation coatings for changes in mechanical and thermal properties caused by the simulated service conditions.
We offer world-class materials expertise in polymers, elastomers, thermoplastics, composites and structural adhesives.
