Problem:

Severe blade abrasion

 
 

Products:

Belzona 1812

Carbon steel

 
 

Application Method:

After removing the remainder of the rubber coating, the blades were welded on the heavily damaged areas. The surface was then grit-blasted before the application of Belzona 1812 according to the SHM-13 Belzona procedure.

 
 

Belzona Facts:

Previously, the mine had to shut down the tank every month to replace the rubber-coated blades. Once coated with Belzona 1812, the blades were inspected after 12 months in service and were in good condition, requiring some retouching on about 10% of the surface: In 2017. the customer asked for a repair of 16 blades for other storage tanks.
