Sandblasting and exterior painting of the T7C fuel storage tank at the Skhira depot – TANKMED

The intervention of THI REVETEMENT consists in renewing the protection system of the fuel storage tank T7C by sandblasting and painting while respecting the execution times which must be as short as possible, the safety standards, the markings of the pipes and the guarantee of maintenance of the applied system which must meet the usual chemical, physical and mechanical constraints in the region of Skhira in southern Tunisia. 

The system begins with the sandblasting of the surfaces to apply the new anti-corrosion paint.

 Sandblasting is done by abrasive projection using compressed air, the degree of sandblasting to be achieved is SA 2.5, the purpose of sandblasting is to expose the steel, the sandblasting operation allows then to remove the rust, the old anti-corrosion painting and any foreign bodies. 

As soon as the sandblasting is finished, the first coat of anti-corrosion painting is applied, the primer coat of anti-corrosion painting is used to protect the bare surface after sandblasting. 

The painting system is further reinforced with an intermediate layer of anti-corrosion painting. The anti-corrosion painting system is finally closed with a coat of waterproof finishing paint. The complete system of sandblasting and anti-corrosion painting applied is able to resist chemical agents, mechanical stress and sunlight.
