Valves coated for a deep sea project

The directional quench valves, which weigh approximately three tonnes, were delivered to Arc Energy’s Gloucestershire facility, as pre-machined body castings.

In order to combat the combined erosion and corrosion attack from an aggressive medium, Arc Energy’s welding engineering team advised a 3mm thick coating of Ultimet, a cobalt-chromium alloy which combines corrosion, wear and impact resistance with high tensile strength.
