Most crude oil tanks are made of steel. Steel is strong enough to hold and protect the oil, but it is subject to corrosion. Your tank more than likely received a protective surface coating during manufacturing, but that coat does not last forever. Maintenance is required and should be considered every 5 to 10 years. Staying ahead on this maintenance will prevent corrosion and in turn, prevent leaks and money lost. There are several types of corrosion that could occur in crude oil tanks.
General Corrosion
This is a normal corrosion that takes place throughout the tank.
Localized Corrosion
Localized corrosion can occur where water collects or flows within a tank. This type of corrosion occurs faster in localized sites, because of surface rust or scale build-up on the tank.
Pitting
This type of corrosion is found along the bottom of tanks and places where water can accumulate. Pitting can also occur when seawater collects, causing microbial or electrolytic corrosion.
Welding Corrosion
Often this type of corrosion occurs when the metal used for welding causes an interaction with the metal in the oil tank. This causes an electrolytic action, which causes corrosion.
