Industry:

Heating, Ventilation & Air Conditioning (HVAC)

 
 

Application:

Heat Exchangers (HEX)

 
 

Customer Location:

Billings, MT, USA

 
 

Application Date:

1986

 
 

Application Situation:

Corroded heat exchanger.

 
 

Problem:

Corrosion caused by the chemicals in the system were eating away the tube sheet and end cover.

 
 

Products:

Belzona 1321 (Ceramic S-Metal)

 

Substrate:

Steel

 
 

Application Method:

The tube sheet and end cover were blasted and coated with two layers of Belzona 1321. It was decided to not use corks because the tube sheet was small. The application was carried out in accordance with Belzona Know-How System Leaflets HEX-1 & HEX-2.

 
 

Belzona Facts:

A new replacement heat exchanger was out of the question due to budget restraints. The cost to repair the equipment with Belzona was far less than the replacement costs.
