Application Situation
The client had a heat exchanger which was suffering from internal corrosion. They required a solution to repair the internal damage and then apply a suitable internal lining to protect the shell from further damage and extended the equipment's life span.
Application Method
The heat exchanger was dismantled and delivered to the Belzona workshop in to two parts - the main shell and the dome end. The internal substrate was grit blasted in our workshop under controlled conditions. The pitted steel within the shell was then repaired using Belzona 1511. Following this two Belzona 1511 Nozzle Inserts were bonded into both drain and vent nozzles on the cap end, guaranteeing total encapsulation within these areas. Following the repair, two coats of Belzona 1593 were applied to provide long-term protection. Completed in accordance with Belzona System Leaflet HEX-03
