Lining service for above-ground vertical diesel tanks

How we work?

To carry out the repair and lining service of above-ground vertical tanks, firstly we need to measure the thickness of the tank and analyse the damage caused to it. If you are unable to provide us with this information, that isn’t a problem.

Rafibra has 30 teams throughout Spain that are carrying out regular servicing, we can send you a team and carry out a visual inspection and measure thicknesses, in addition to conducting a leak test to check whether the tank is airtight or if it contains any perforations.

Repair and lining of above-ground vertical diesel tanks

THE REPAIR OF ABOVE-GROUND VERTICAL TANKS OF CHEMICAL PRODUCTS SUCH AS ACETONE, ALCOHOL, ACETATE AND HYDROCARBONS As they are above-ground, these tanks are highly exposed to changes in temperature, in addition to the sun, wind and rain that strikes and damages the steel on the tank, both externally and internally. Rafibra’s wealth of experience in lining above-ground vertical tanks, both in France and Spain, shows us that corrosion is always found at the bottom of the tank.  Why does this corrosion occur at the bottom of above-ground vertical tanks? In confined spaces, there are 2 grave dangers.
  1. The corrosion of the tank due to ground water levels or parasitic or stray currents. The bottom of the vertical shaft tank is the only area that cannot be inspected from the outside and, furthermore, the only area that is in contact with the ground, so it can be susceptible to these issues occurring.
  2. Humidity due to condensation.All tanks always have an air gap which is not taken up by the product. With the changes in temperature, this air condenses into drops of water which fall to the bottom of the tank because of their own weight.
That’s why most vertical tanks are damaged at the bottom. We carry out the repairs and lining on the base of the tank and up to a metre high, since they are usually the areas most affected by corrosion. However, we always conduct a separate study for each tank with measurements, thicknesses and photographs of the tank’s condition.
