Fine Tubes targets two-year audit cycle for Nadcap heat treating processes
Fine Tubes has long history of manufacturing precision tubes for a wide range of applications in which performance is critical. The company also has long recognised the importance of Nadcap, a leading accreditation programme for all the critical manufacturing procedures undertaken across the aerospace industry’s supply chain.
Rob Eatwell, Quality Manager at Fine Tubes explains: “Nadcap is a key part of the Quality Management System at Fine Tubes. The first accreditation was awarded for Heat Treating in 2004 followed by Non-Destructive Testing, i.e. Ultrasonic Testing in 2005. Since then Fusion Welding was added in 2013 and now assessment for both Chemical Processing and Fluid Distribution Systems are scheduled for 2017. Due to the consistency of successful assessments Fine Tubes is now on the Nadcap Merit programme for all three disciplines.”
To ensure that Nadcap approvals establish the necessary confidence in a supplier, audits are typically carried out on an annual basis. Fine Tubes is targeting a two-year audit cycle from Nadcap for its Heat Treating processes after having fulfilled all the necessary criteria.
Val Hart, Technical Manager at Fine Tubes comments: “This would put us in quite an exclusive club. There are not many organisations that have a two-year audit status. She adds: “Our Heat Treating audit was very much based on the way we use our furnaces. We had to demonstrate that we could always maintain a temperature within a very narrow band - plus or minus 10 degrees. It’s a strict process, but it does mean we can assure our customers that all the heat treatment undertaken on their tubing products has been conducted within a specified range. And, because the accreditation is recognised internationally, it means that aerospace companies don’t have to conduct their own supplier audits, and suppliers don’t have to be subjected to multiple audits from potential customers. It’s a programme that works for everyone right across the supply chain.”
