Belzona® Takes The Heat In Exchangers

 
 

Industry:

Petrochemical (PETR)

 
 

Application:

Heat Exchangers (HEX)

 
 

Customer Location:

Petrochemical Plant, Teesside, UK

 
 

Application Date:

2016

 
 

Application Situation:

Brine Heat Exchanger

 
 

Problem:

The brine heat exchangers operate at up to 138°C and are prone to rapid corrosion. The water box, separator channels and tube face had all suffered extreme corrosion and the separator plate was being bypassed.

 
 

Products:

Belzona 1511 (Super HT-Metal)

Belzona 1593

 

Substrate:

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.
