Belzona 4311 (Magma CR1)


Problem: An unwanted reaction within these assets is the formation of hot hydrochloric acid, which was then attacking the steel spirals. It was thought that there were only a few weeks left before the heat exchanger would fail. The lead time on a replacement was nearly 12 months.

Belzona Facts
The replacement cost for this heat exchanger was over £230,000. Belzona was used to coat the affected areas on both ends of the asset with a material that can withstand hydrochloric acid, even at 60°C. The whole application was completed with only minor material costs of about £600. The client then repeated the application on a further two identical spiral heat exchangers the following year.
