Four components from various vessels were heavily eroded and required internal repairs and coating to restore them, improve longevity and performance.
Each component was in a heavy state of erosion suspected from chemical attack. Substrate preparation was carried out with conventional grit blasting with an angular abrasive to achieve a minimum surface profile of 75µm and a surface cleanliness of SA 2½.
After surface preparation, the components were reprofiled with Belzona 1511, then coated with Belzona 1391T to protect the components from future chemical attack.
Belzona 1391T was chosen to complete the repairs due to its proven success on other process vessels at their site over the years.
The Heat exchanger components were restored and reinstated back into service, saving the client from prolonged shutdown periods and considerable cost of replacing the components.
