DTEC Applies Vclad To Chemical-Plant Process Tower
DTEC has completed a multi-column turnkey project at a chemical plant located on the east coast of the UK. The project focus was on the refurbishment of a stainless-steel process tower with a diameter of approximately three metres, which required a corrosion-resistant weld overlay CrNiMo-3 (Alloy 625) onto a stainless-steel base material. DTEC achieved this without incident, using Vclad Weld Overlay technology. Vclad combines digitally controlled synergic welding technology with multi-directional programmable automation. The result is a high quality and productive weld-overlay process that can be applied to many repair and upgrade scenarios, ranging from replacement of original equipment design materials through to the application of corrosion-resistant alloys. Weld procedures are qualified to both ASME and EN standards, and because DTEC holds a library of typical PQRs, it can react to unknown scopes often found during routine turnaround inspections. Due to the flexibility of the Vcla...
