James Walker has launched the first of its next-generation elastomers that is designed to improve elastomer sealing performance for the oil and gas industry.

While testing to establish the limits of the new polymer architecture still ongoing, the FR68/90 elastomer has already exceeded Norsok compliance specifications, achieving a perfect test result not only at 8.4mm section at 100C, but also at 5.33mm section at an elevated temperature of 150C, according to James Walker.

FR68/90 retains flexibility for ease of fitting and is claimed to offer excellent sealing properties with compression set figures of eight per cent after 24 hours at +175C and 10 per cent after 24 hours at +200C.

With its Amine and H2S resistance, plus an operational temperature capability of -30C to +200C, FR68/90 could extend the use of elastomeric materials to larger sections than previously possible, with no loss of RGD resistance.

This could eliminate the need for complex and costly re-engineering of components to accept physically larger solutions such as spring-energised PTFE seals.

James Walker and Co

James Walker is a dynamic global manufacturing organisation that supplies a vast range of high performance fluid sealing products and associated knowledge-based services to virtually every sector of industry. Our activities range from research and development, product application, manufacture and supply, to plant monitoring, on-site maintenance and seal refurbishment. An intimate knowledge of the industrial plant and processes used by our customers worldwide enables us to solve their fluid sealing problems with best value systems designed to minimise total cost of ownership.

State-of-the-art skills in materials technology, particularly relating to elastomers, polymers, composites and engineering plastics, are central to our success — in addition to the core disciplines of high performance sealing technology and tribology. Extensive expertise in the precision machining of exotic alloys for metallic seals, and tension control fasteners for bolted joints, positions us firmly at the forefront of these technologies. We therefore claim that our products and expertise help to keep industry worldwide running safely and efficiently year-in and year-out.

Our worldwide family of companies has 11 production, engineering, distribution and customer support sites in the UK, and a further 40 spread across Continental Europe, Australia, New Zealand, SE Asia, South Africa and the USA. At the local level, a close-knit network of James Walker companies and official distributors supplies our products and services to over 100 countries. Highly developed e-commerce systems and logistics operations give customers the surety of supply they need. We also work in partnership with customers at all levels. The long-term contracts we forge with multinational corporations cover the requirements of their plants across many continents.
