OVERVIEW: This petrochemical client had a fuel oil storage tank which required re-coating. The coating system requirement was for a long term corrosion solution that will provide in excess of 15 years of service as the previous coating had failed.

ENVIRONMENT
Immersed, ambient, possible MIC
SUBSTRATE
Steel floor with failed coating
CHALLENGE
This petrochemical client had 40m diameter fuel oil storage tank with floor and 2m wall which required re-coating. The coating system requirement was for one which offers a long term corrosion solution that will provide in excess of 15 years of service. Time-constraint as the tanks had to return to service as soon as possible.
SOLUTION
We recommended coating with Chemco RA 564, a glass-flake reinforced epoxy resin system that can provide long term corrosion protection in the storage tank for more than 15 years. This coating also provided extremely fast turnaround and cure time, the oil storage tank could be returned to production quickly. The coatings moisture tolerance meant there was no requirement for de-humidification, hence cost is reduced and no delays with weather.
SCOPE
Abrasive blast to Class 2.5 AS1627.4
Application of 2 coats of RA 564 to a DFT of 100 microns
PRODUCTS
OUTCOME
This solvent free, no odour, no VOC coating solution also meant there were reduced OHS concerns, and no impact on the environment and no restrictions with surrounding trades. The coating’s long term protection also meant the client’s future maintenance costs have been reduced dramatically.
