Belzona® Reclaims Rubber Lining Of Water Filter In Steam Generator

 
 

Industry:

General Industry (GIND)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Steam Generating Plant in Venezuela

 
 

Application Date:

February 1996

 
 

Application Situation:

Rubber lined water filter; 6.7m long, 3.5m diameter

 
 

Problem:

The original rubber lining was cracked, particularly at the points where it was anchored to the substrate. As a result the filter leaked and lost efficiency.

 
 

Products:

Belzona® 2111(D & A Hi-Build Elastomer)

Belzona® 2131(D & A Fluid Elastomer)

Belzona® 1311(Ceramic R-Metal)

Belzona® 1321(Ceramic S-Metal)

Belzona® 1211(E-Metal)

 

Substrate:

Rubber, Stainless Steel

 
 

Application Method:

In accordance with Belzona Know-How LeafletsTCC-3 and VPF-13.

 
 

Belzona Facts:

Hot vulcanising the damaged areas of the rubber lining was ruled out as being too hazardous in a plant powered by natural gas. The Belzona coating also gave enhanced efficiency of about 9% over the rated performance. Replacing the unit would have cost in excess of £125,000 compared with Belzona costs of £8,000.
