Abstract
At one of our customer/end-user chemical plants in Singapore, they had a problem with frequent replacement of the Hastelloy C impellars casted used in their centrifugal pumps in service with Sodium Hypochlorite application. The existing impeller were always noticed with severe pitting corrosion damage and often required a quick turnaround to replace the parts back to service.
