Reducing corrosion in tank pads

Challenge

The gap in the tank pads between the metal bottom siding and the concrete pad had been one of the major problems of the newly installed diesel storage tank of the Semirara Mining Corp. these gaps were already filled in previously with asphalt to fill in the gaps. But since asphalt are high porous and becomes brittle when exposed to high temp, the problem of the gap was still a big problem. If not sealed, factors of corrosion such as water vapor and air would penetrate the bottom plate promoting the formation of corrosion. If left unattended, it might cause great irreversible damage.

Solution

Products Used: ARC 855 & ARC 988

Scope of Work: It includes proper surface preparation for both metal and concrete to achieve the appropriate angular surface profile requirement, cleaning of the surface from other contaminants prior to the ARC application, the actual ARC application for the metal, then sealing of the gap and concrete by ARC. After the curing time, the thickness of the applied ARC would be determined to assess the applied thickness with respect to the requirement.

Results

A total of 4 diesel storage tank pads were sealed using the Chesterton ARC Technology. The possible formation of stress corrosion is already prevented by the application of ARC 855 the gap between the metal and concrete was sealed using ARC 988, thus ensuring the prevention of vapor and moisture permeation on the bottom plate. After 5 years, the applied ARC technology is still intact.
