Welding and Fabrication experts for ASME U & U2 compliant projects


Arc Energy Resources is a proud holder of ASME U & ASME U2 Stamps, enabling us to provide a range of services from full supply of ASME code compliant equipment and pressure vessels to subcontract welding on free-issue ASME standard material.

Fabrication Experts

For fabricators of ASME U Stamp vessels, the ASME Code requirement that any welding activities must be carried out in an accredited shop has been a significant challenge when subcontracting parts for weld overlay cladding.

Weld Overlay Specialists

As a weld overlay specialist holding the ASME U, ASME U2 and National Board Stamp certificates, we are the ideal solution to this problem. We can weld on customer free-issued parts or manufacture complete components, including full vessel design, verification and supply.

Our supply includes:

• Nozzles, as small as 20mm.
• Elbows, tees and reducers.
• CRA clad pipe, supplied straight or induction bent.
• Dished ends for vessels and exchangers.
• Vessel strakes up to 4m in diameter, 6m long.
• Heat exchanger tubesheets.
• Fabricated piping sub-assemblies with weld overlay.
• Clad or solid corrosion resistant alloy materials.
