Quench valves for deep sea project
9 May 2013
Weld overlay cladding and fabrication specialist Arc Energy Resources has recently completed the coating of three large quench valves for a major offshore oil & gas installation.
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 erosion and corrosion, Arc Energy’s welding engineering team advised a 3mm thick coating of Ultimet, a cobalt-chromium alloy.
Some of the surfaces to be clad were not directly visible nor did they provide good accessibility.
Because of the need for control of a welding head moving in 3 axes and in a variety of welding positions, cold wire TIG was selected.
After cladding, all surfaces were tested to confirm the surface integrity and checked for thickness of deposit.
