Cladding
Weld overlay cladding is a process that provides protection for metallic components by welding a layer of corrosion-resistant alloy to areas at risk of corrosion and wear. It can be applied to an entire component, or only to specific areas of concern. Typical components clad by Arc Energy include pipes, valves, flanges, connectors, and elbows, as well as more complex geometries such as tee pieces and wye pieces.
Benefits of Cladding
Cost
Fully cladding a carbon steel component with alloy 625, as opposed to producing it in solid alloy, can reduce costs by as much as 60%.
Flexibility
- Only clad the areas at risk. Typical areas include pipe bores, connector seals, ring grooves, valve seats and flange faces.
- Select appropriate overlay materials for your application.
Delivery
Buy carbon steel components off-the-shelf and clad them in days, rather than waiting 12-16 weeks for specialist forgings.
Quality
- Exotic alloy castings can include sub-surface defects. Cladding the surface produces a very high-quality layer with minimal imperfections.
- A full range of NDT provides reassurance of quality.
Pipe Cladding
Protect internal piping from high-pressure corrosive fluids through specialist weld overlay pipe cladding. The process prevents corrosion and damage to pipe systems and avoids potential repair and replacement issues.
Valve Cladding
Valves introduce high pressure points along a pipe system. Arc Energy’s robotic arms allow for 360 degrees of continuous welding from pipe to valve, retaining the overall core strength of the system.
Flange Cladding
Flanges are crucial points in pipework that introduce high pressure points in the overall system. Effective overlay cladding prevents corrosion of the pressure points and stabilises the pipeline throughout the system.
Specialist Fabrication
Effective specialist fabrication is required on a wide range of systems across countless industries. Arc Energy combine core activities of weld overlay cladding and specialist fabrication to prevent corrosion at critical points in aggressive environments.
Corrosion Resistant Properties
Arc Energy’s weld overlay cladding services are utilised by clients in a vast number of industry sectors where service conditions require corrosion resistant properties. Weld overlay cladding provides the assurance of a heavy-duty metallurgically-bonded protective layer that will not be undermined or dislodged in service. Welding can be overlayered to an application externally (ie flange face) or weld inlay internally (ie through a pipe bore).
Integrity of the cladding can be confirmed in-house via a variety of non-destructive testing (NDT) methods including dye penetrant and ultrasonic.
Materials
Typical materials for cladding in common use at Arc Energy include alloy 625, alloy 825, Monel 60, Hastalloy C-22, Hastalloy C-276, Ultimet, Stellite 6 and stainless steels, as well as many less common alloys.
With over 5,000 qualified weld procedures, and the technical expertise to back them up, Arc Energy can meet any base material and cladding combination.
