Customer Location:

Belzona 1511 (Super HT-Metal)

Belzona 1593



Carbon Steel


Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflets HEX-1, HEX-2 and HEX-3.


Belzona Facts:

The customer had tried several materials previously on these heat exchangers and because of the severely corrosive and elevated temperature service conditions, none had lasted more than a year or two. Belzona 1593 is designed for permanent immersion conditions up to 160°C and so it was the ideal coating to protect all parts of this asset.
