Large Ti Furnace Hydraulic Modifications

Description

The requirement is for the servicing and modernization of the VAC 4 titanium vacuum arc re-melting furnace (304170) hydraulic system. The VAC 4 is a unique national research asset and the largest furnace of its type in the UK, enabling strategic development of largescale titanium castings. Reliability issues have arisen due to the hydraulic control system design, which now requires modification to ensure safe and reliable operation. The scope includes replacement of actuator seals, system flushing, and modernization of the hydraulic tank (bulkhead transitions, filter adapters, breather filter, condensate drip tray with drainage). The works also cover modification of the Power Ram actuator, including installation of three counter-balance valves. On-site attendance will be provided by SWSA and B&I Hydraulika teams for 3 weeks, extended to 5 weeks with an additional fitter if required. Due to the bespoke nature of the equipment, only the original equipment manufacturer has the technical knowledge and authority to undertake these works while maintaining UKCA compliance.
