Belzona® Repairs Oil Tank Leak



Oil & Gas (OILG)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Oil Refinery, Thailand


Application Date:

November 2008


Application Situation:

Leaking Oil Tank



The roof deck of the tank had been subjected to severe corrosion leading to a local leak of the oil vapour. This was very hazardous to the plant operation and there was also a risk of rain water contamination into the tank.



Belzona® 1161 (Super UW Metal)
Belzona® 5831 (ST Barrier)




Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflets TCC-1 & -5. The surface was cleaned by wet sand blasting to avoid hot work and spark. Belzona® 1161 was then used in conjunction with four layers of Belzona reinforcement sheets to prevent further leakage. Belzona® 5831 then applied to protect against further corrosion.


Belzona Facts:

The surface tolerant properties of Belzona® 1161 & Belzona® 5831 allowed the application to be done on a wet blasted and oil contaminated surface which provided a quality repair safely.
