Evaporator Barrel Protection With Belzona

 
 

Industry:

Food & Drink (FOOD)

 
 

Application:

Solids Handling Machinery (SHM)

 
 

Customer Location:

Virginia, USA

 
 

Application Date:

March 2009

 
 

Application Situation:

Creating a secondary containment barrier around an evaporator in need of replacement. Tobacco processing company. 

 
 

Problem:

The evaporator barrel is corroding from the inside out and springing leaks, which causes a temporary shutdown to repair the leak. The customer wanted a solution that would allow them to keep operating should a leak occur until they could plan a shutdown for a more permanent repair or replacement.

 
 

Products:

Belzona 2911 (Elastomer QD Conditioner)

Belzona 2121 (D & A Hi-Coat Elastomer)

Belzona 9331 (Reinforcing Sheet)

 

Substrate:

Mild Steel

 
 

Application Method:

The application was crried out eih a modified version of Belzona Know-How System Leaflet. An orbital sander with a scotch brite pad was used to lightly abrade the surface, which was too thin to achieve an ideal preparation. The surface was cleaned with MEK. A heavy coat of Belzona 2121 was applied, the barrel was wrapped with Belzona 9331 and a second heavy coat of Belzona 2121 was applied.

 
 

Belzona Facts:

Providing a secondary containment barrier for the evaporator allows the customer to keep operating should an untimely leak in the barrel occur, as well as plan for a permanent repair to the barrel or replace the evaporator. This saved them time and money from possible shutdowns.
