Meeting new challenges for high performance spring in critical aerospace application

WILLIAM

Hughes

has

been

manufacturing high specification springs for many years, and is equipped to meet the exacting demands of the aerospace industry including its special requirements for materials, specifications, manufacturing tolerances, cleanliness and packaging. A recent example of a spring for a safety critical aerospace non-return valve presented new challenges to the design and production team at William Hughes. The application required a large spring which, as well as being manufactured in a specialist aerospace-certified material – which has a high spring index making it difficult to form – the unusual specification called for one end of the spring to be fusion welded using stainless steel filler rod. Following the welding process, the end coils have to be cleaned to ensure that they are uniform with no protrusion, this being achieved using a series of grinding, polishing and deburring processes. The opposite end is then fettled on the inside to allow correct location on the valve housing, and both spring ends are chamfered and deburred. The spring is heat treated and passivated in William Hughes’s NADCAP oven process before being 100 per cent checked for squareness and load. Springs manufactured by William Hughes are being used in vital items of aerospace equipment including oxygen systems, access hatches and the solenoid valves used to control the hydraulic and cabin pressure systems. The company offers its customers a rapid design and prototyping service in a range of materials. This facility is particularly suited to the aerospace industry, where small quantities are required for prototypes with the capability to move to volume production once a final design is agreed. Quality systems to ISO 9001:2000, ISO/TS 16949:2002 and AS9100 – the quality management system standard for aerospace companies – ensure precision,

In addition to precision specialist springs, William Hughes can also supply bespoke bent wire forms and sub-assemblies. William Hughes Ltd – UK Website : www.wmhughes.co.uk Nucor Steel Seattle has officially signed off on Tenova’s Water Detection System® (WDS). The system was approved based on controlled testing and successful detection of actual EAF water leaks. These results confirmed that the WDS met the plant’s requirements to detect and alert plant operators when higher than normal water conditions were present in the EAF. The WDS has also demonstrated minimal false alarms even in Seattle’s highly variable seasonal weather conditions. In addition, the NextGen® + i EAF® project, previously commissioned in April 2016, surpassed Nucor Steel Seattle’s expectation for quantifiable and sustainable improvements in monthly process consumptions and operating costs: average monthly furnace consumptions were significantly decreased in the following areas: 5 per cent electrical, 1.5 per cent oxygen, 11.5 per cent natural gas, 7.5 per cent injected carbon and 32 per cent charge carbon. Complete system performance has more than doubled from the original estimated savings target determined at the start of the project, with total electrical and chemical energy costs per ton of steel being reduced by over six per cent.
