SCOPE OF WORK
After analysis of the tank and defect characteristics, it was decided to temporarily repair the installation using the TANKiT®. This solution is perfect for emergency online repair required by the client.
The work team carried out the surface preparation, using Bristle Blaster® machine, to remove the coating and to get a good surface roughness (greater than 60 µm) to ensure the adherence between the tank and the composite solution. Hygrometric conditions were checked and the surface was cleaned and degreased with ethanol.
Composite repair was then performed as per the following steps:
- F3XS1 filler was first applied over the defect to stop the leak and level the surface.
- F3X8 filler was then applied to create a barrier against the corrosive environment and to facilitate the adhesion of the metallic plate.
- Metallic plate was applicated over the defected area using a thick layer of F3X8 filler to seal the leak.
- Once the curing time of the fillers was reached, the patches installation was started. Kevlar® patches impregnated with R3X5 were applied to repair the tank. It was necessary to install 5 Kevlar® patches corresponding to 5 layers.
- Finally, anti-UV coating was applied to protect the repaired area and identification plate was installed for traceability.
