Sand Filter Lining Repaired With Belzona

 
 

Industry:

Petrochemical (PETR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Chemical company, Martorell, Spain

 
 

Application Date:

March 2010.

 
 

Application Situation:

Ebonite lining in sand filter

 
 

Problem:

The ebonite lining showed severe degradation (cracks, grooves, gasket failure, adhesion problems) due to the corrosive action of the solution (brine 250 gr/Kg, active Cl2 0-20 ppm) at 65ºC.

 
 

Products:

Belzona® 1111 (Super Metal)

Belzona® 5891 (HT Immersion Grade)

 

Substrate:

Ebonite.

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet TCC-3 & 5.

 
 

Belzona Facts:

Thanks to the Belzona products, the filter was back in service after a rapid, easy and in situ repair. The cost of replacing ebonite would have been much higher. Belzona enabled a quick in-situ repair to be carried out, ensuring filter could returned to service with minimum disruption to production. Alternative (replacing ebonite) would have taken far longer and at far higher cost
