Problem:

Due to severe corrosion a critical leak occured while preparing the surface of the pipe externals. The surface is constantly moist and condensing, this made drying of the application surface very challenging.

Belzona 1221 (E-Metal)

Belzona 1212 

 

Substrate:

Carbon steel

 
 

Application Method:

Application was carried out in accordance with a modified version of Belzona Know How System Leaflet VPF-11. Belzona 9611 and Belzona 1221 were used to succesfully stop the leak within minutes. This was followed by an application of a composite wrap using Belzona 1212 to seal the area.

 
 

Belzona Facts:

Due to the moist conditions and constantly condensing surface a rapid curing, surface tolerant solution was crucial. The Belzona solution avoided a major shutdown of the factory. The Belzona repair allowed to factory to continue production until the next planned shut down.
