New universal sealing disc for sliding gate valves

West Special Fasteners, the Dronfield based manufacturer of high integrity fastening products to the oil and gas industry, completed its first Subsea Chemical Injection Metering Valves (CIMV) fastener order since joining the BVAA.

‘We are proud of our BVAA membership,’ said Director James Hawkins ‘and fasteners for CIMV is a product which is very relevant to the industry, so the successful completion of this order is a milestone for us.’

Chemical injection is an important part of oil and gas production. Chemicals are injected subsea to mitigate flow assurance & corrosion risks. A CIMV is an extremely important part and so the fasteners used on such a critical parts have to be highly tested and inspected.

West Special Fasteners has supplied several Valve companies in the UK with special fasteners; with some of the relationships dating back years. The company also has a European Valves manufacturer as a regular customer; however this is the first Valves manufacturer it has supplied outside Europe.

The project was for 3500 components of various sizes from M6 to M24, including Nyloc nuts, Socket Capscrews, etc in Stainless Steel grade A4-80 but tested to the highest standards. The technical specifications included every conceivable test including LPI (Liquid Penetrant Inspection), Chemical Analysis, Hardness, Tensile Test, Yield Test, Elongation Test, also full size Breaking Torque Tests, Proof Load Tests, and Destructive Bolt testing as per ISO 3506.

‘When it comes to this critical process, contractors need to be able to trust each component supplier; fortunately West Special Fasteners’ experience in this field means the company is an extremely reliable partner’ adds James Hawkins.

West Special Fasteners is very familiar with ISO 3506 and helps with test data submission to the BSSA (British Stainless Steel Association). All of the components passed, all the tests, with flying colours.

The project was completed within 5 weeks, on time and sent to the customer via airfreight due to its urgency.
