Nozzle flange faces on offshore process vessel due for urgent delivery
The flange faces were reblasted fully and Belzona® 1591 was installed using a forming process according to Belzona Know-How System Leaflet VPF-13.
Four flange faces were formed using this technique, and were allowed to cure prior to breaking out. Once complete they were protected, the vessel was grit blasted for a second time and Belzona® 1591 applied to the whole vessel. The alternative would have required on-site machining of the flange faces at significant cost.
