Industry:

General Industry (GIND)

 
 

Application:

Roof Problem Areas (RPA)

 
 

Customer Location:

Fertiliser Plant, France

 
 

Application Date:

October 2018

 
 

Application Situation:

Aluminium roof of a process tower

 
 

Problem:

The roof of a process tower in this fertiliser plant was leaking due to the chemicals that were attacking the welds. Infiltration of water was becoming problematic for the production and the roof had to be fixed.

 
 

Products:

Belzona 1111 (Super Metal)

Belzona 1161 (Super UW-Metal)

Belzona 1212

Belzona 3121 (MR7)

 

Substrate:

Aluminium sheets

 
 

Application Method:

The previous repairs were removed and Belzona 1111, 1161, 1212 and 9341 (reinforcement sheet) were used to seal the gaps. Then two coats of Belzona 3121 were applied on top of the repairs to seal in accordance with Belzona system leaflet RPA-1.

 
 

Belzona Facts:

After a commercial prospecting from the distributor, the customer decided to go for a Belzona solution. The other classic sealing methods with silicon or resin did not withstand the conditions. Welding was not allowed on site because of the presence of chemicals, and would still leave the area prone to corrosion. The fact that the whole application could be carried out without any hot work was a great advantage for the customer.
