FR60/90 Brochure - .PDF file.

In the updated product brochure for its FR68/90 Rapid Gas Decompression (RGD) resistant elastomer material, James Walker has included a guide to the interpretation of Norsok test results and ratings.

The short guide outlines the potential damage that a seal material could have sustained at each rating level, demonstrating that a material could be seriously compromised, so as to provide little or no operational safety margin, yet still claim to have passed the Norsok M-10 Rev 2 Annex B test for rapid gas decompression resistance.

The publication’s diagrams and photographs are targeted to show why James Walker uses the 0000 rating, meaning zero damage, as the key benchmark for its own materials – this being the only rating at which the material has suffered no visible damage under test.

According to James Walker, its latest product in this arena has established new performance benchmarks, recording a 0000 rating at up to 10mm section and up to 150C.

Although an advanced test programme continues with further passes expected at higher temperatures and even larger sections, James Walker claims that the current results place the FR68/90 material in a league of its own with regard to RGD performance, particularly when other secondary performance criteria such as resistance to amines, sour environments, hot water or steam are also taken into account.

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.
