Industrial Members of TWI are being invited to two webinars taking place this autumn that are likely to be of interest to industry sectors working with cement, concrete and polymers.
Webinar one: Opportunities for support on cement-related issues
TWI has acquired expertise in the area of cementing, supported by a bespoke testing facility.
This webinar, on 5 October, will include a description of key issues relating to cement usage in oil and gas wells. There will also be a presentation on degradation mechanisms more generally found in cements and concrete used in nuclear power stations, wind turbines or oil and gas applications.
Our combination of high-level expertise and bespoke testing facilities means TWI can provide services including characterisation of cement’s chemical and mechanical properties and insight into ageing and degradation behaviours of cement- and concrete-based materials in complex harsh fluid environments. TWI’s established corrosion engineers are able to assist with matters relating to corrosion assessment of steel–concrete systems, including cathodic protection, in all industry sectors.
This webinar will be presented by Dr Bernadette Craster and Dr Maria-Eleni Mitzithra.
Webinar two: Polymer layers as corrosion protection for carbon steel
Protecting steel pipelines and other metallic components from corrosion is a topic of continual interest and development for the oil and gas sector. One way of achieving this is the introduction of pre-moulded polymer layers to cover the metal surface. This webinar, on 12 October, will reveal the results of research designed to establish an effective method of evaluating these barrier layers, with the ultimate aim of improving their efficiency.
The research focused on the thermoplastics polyether ether ketone (PEEK) and polyphenylene sulphide (PPS), commonly used for high-temperature applications. Permeation and exposure testing involving gaseous and supercritical carbon dioxide mixes was carried out on PPS with varying crystallinities. In some situations the pressure was gradually increased to 400barg at a temperature of 100°C. In all cases infrared spectroscopy and differential scanning calorimetry were used to interpret the findings. In addition, using a unique osmotic cell operating under ambient conditions, the transport rate of ions from seawater mixtures through moulded PPS and PEEK was studied for the first time.
This webinar will be delivered by Dr Bernadette Craster, who led the research.
Each webinar will be presented twice on its advertised date, at 10am and 2pm British Summer Time. Each will last around 30 minutes, followed by time allocated for questions.
Attendance is free but open only to Industrial Members of TWI. For more information, contact us.
