Industry:

Petrochemical (PETR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

International chemical company, Spain

 
 

Application Date:

April 2012

 
 

Application Situation:

Ebonite lined process vessel operating with 10-35% Hydrochloric acid.

 
 

Problem:

The internal ebonite lining was damaged around the vessel support areas where the ebonite had disbonded leaving the steel exposed.

 
 

Products:

Belzona® 4301 (Magma CR1 Hi-Build)

 

Substrate:

Ebonite and steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet TCC-3. The surface was prepared removing the previous mastic products. Then, the ebonite was roughened using a grinder and the whole application area was grit blasted to ensure a minimum 75 micron surface profile on the exposed steel before rebuilding all damaged areas with the Belzona® 4301.

 
 

Belzona Facts:

This application was carried out in-situ, repairing the ebonite lining without the requirement of a vulcanization process, and minimising downtime and disruptions to the client facilities and operations.
