Weld overlay cladding specialist Arc Energy Resources has signed a contract to clad 16 valves for Goodwin International.

The 12in dual plate check valves are being supplied to John Bell Pipeline, main contractor for the In Amenas Trunklines, the largest wet gas project in Algeria, involving the development and production of LNG from four wet gas fields.

The check valves are cast and machined in carbon steel and then shipped to Arc Energy’s Gloucestershire factory for weld overlay cladding, with Inconel 625 being applied to all wetted surfaces.

The corrosion-resistant surface will enable the valves to resist highly corrosive fluids, to give the end user an alternative to a valve cast in solid Inconel.

Arc Energy Resources

Arc Energy Resources is one of the UK’s leading specialists in weld overlay cladding and quality-assured fabrication services with a turnover approaching £5m, employing 70 staff in work space totalling more than 30,000ft2. The company’s expertise in weld overlay cladding services provides heavy-duty protection against corrosion and wear for process and pipeline equipment destined for use in any hostile environment. It can clad bores up to 4m in diameter and areas of restricted access within bores as small as 20mm in diameter.

The manufacturing infrastructure is qualified to ISO 9001:2008, ISO 3834-2, ISO 14001:2004 and ISO 18001:2007. The company also holds ASME U and R stamp certificates of authorisation, which qualifies it to fabricate and weld on components destined for use on pressure vessels built to ASME standard.

Arc Energy’s welders and fabricators are qualified to internationally recognised standards and specifications. A wide range of base metal/cladding combinations has been qualified to ASME IX, API 6A and NACE. In addition, Arc Energy offers in-house test weld, heat treatment, PMI and NDT facilities.

Arc Energy has recently invested £500,000 in two new rotating-head welding machines to increase productivity and extend the size and scope of work the company can handle. While conventional workstations move components around a fixed welding torch, the new machines use automated controls to manipulate the welding torch around a fixed component, accurately positioning it to apply the overlay while working close to the component’s footprint. The investment expands and enhances Arc Energy’s ability to handle complicated component geometries for the full or partial cladding and fabrication of a huge range of component sizes weighing anywhere up to 15 tonnes.

Managing director Alan Robinson is one of very few UK-registered European welding engineers. He has a Master's degree in welding and is a chartered engineer, a European engineer and a senior member of the Welding Institute. He has assembled a highly skilled team capable of delivering quality service from enquiry to delivery and beyond, which can engineer the perfect solution to the biggest of challenges.
