Anti-corrosion treatment process
After completion of erection works, the surfaces cleaning and further anti-corrosion primer treatment are performed.
Prior to tanks commissioning, hydraulic tests for tightness and strength are carried out: vertical tanks are filled with water to the design level, horizontal and spherical tanks are filled with water under the pressure exceeding the working pressure.
The roof is checked by pouring water up to the roof level, which increases the internal pressure on the roof.
