Belzona® Solves Holed Tank & Handrail Problem

 
 

Industry:

Petrochemical (PETR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Chemical Manufacturer (Chromium), UK

 
 

Application Date:

May 2005

 
 

Application Situation:

Holed chemical tank & corroded handrail support.

 
 

Problem:

General corrosion on this old chemical tank had left a hole at the top under a handrail support.

 
 

Products:

Belzona® 1111 (Super-Metal)
 

Substrate:

Steel

 
 

Application Method:

The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet TCC-5. After a preparation involving needle-gunning & abrading a support plate was bonded onto the underside of the repair area using Belzona® 1111. Once this had cured the whole area was then rebuilt using Belzona® 1111 incorporating reinforcing sheet.

 
 

Belzona Facts:

No hot work was allowed when the tank was in use so the customer originally wanted the repair to last to the next shutdown in 9 months at which time they planned to carry out a fabrication repair. After inspection during the shutdown they decided the Belzona repair was sound & a fabricated repair was not necessary.
