Arc Energy Resources Clads Quench Valves for a Deep Sea Project
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 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 excellent corrosion, wear and impact resistance with high tensile strength.
The complex internal geometry of the as cast surfaces of the valve necessitated precise set up and close control of Arc Energy’s mechanised welding equipment. 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 from Arc Energy’s vast library of welding procedures and techniques, ensuring that the inner surfaces of the ball valve received a consistent, high-quality layer of weld deposit.
After cladding, all surfaces were successfully tested to confirm the surface integrity and checked for thickness of deposit.
Commenting for Arc Energy Resources, managing director Alan Robinson says “rising to the challenge of cladding complex geometries and engineering the perfect solution to any weld requirement is what we excel at”.

Arc Energy Resources is one of the UK’s leading specialists in weld overlay cladding and fabrication for the oil & gas industry. The company’s expertise provides protection against corrosion and wear for a variety of process and pipeline equipment for use in any hostile environment.
The company recently made a major investment in two new Rotating Head welding machines costing £500,000. This has increased productivity and extended the size and scope of work it can handle, which now includes complicated component geometries for the full or partial cladding and fabrication of a huge range of component sizes weighing up to 15 tonnes. The company’s in-house designed cladding workstations feature state-of-the-art control systems developed to suit its customer’s specialised engineering requirements, and can clad bores up to four metres diameter and areas of restricted access within bores as small as 20mm diameter. Arc Energy also offers in-house test weld, heat treatment, PMI and NDT facilities.
Industry certifications include ISO 9001:2008 quality management, ISO 3834-2 fusion welding of metallic materials, and the internationally renowned ASME U and R Stamps, as well as ISO 14001:2004 environment management, Investors in People and OHSAS 18001:2007 Health & Safety management system.
