Fabricated using SAW (tandem arc), GTAW, FCAW Welding processes. We also used Semi-automated circle SAW machine on the larger nozzles. CRO (Corrosion Resistant Overlay) was performed on all nozzle bores and faces. 30mm strip electrode was used for all LS and GS lane closures. All edges of cladding we mechanically stripped back prior to welding the backer material.
This was a stacked vessel that were built and PWHT separately, with a local heat treat on the closing weld. We installed trays, a demister and fireproofing. The internal head was 3” thick.
