To achieve cathodic protection of the vessel with a sacrificial anode system, certain tools and techniques must be used. Vessels are among the structures that are most exposed to corrosion due
In the sacrificial anode method, the current required to combat the corrosion of the structure is provided by another metal, which is usually made of zinc, aluminum and magnesium. Because these sacrificial anodes do not have the ability
Both sacrificial anodes and impressed current system are used for cathodic protection of aboveground storage tanks. In this method, the protection of the inner surface
The type of backfill used in the cathodic protection system in ground substrates depends on the type of cathodic protection system used. Due to the fact that the cathodic protection system
Mixed metal oxide anodes are made of a titanium substrate coated with mixed metal oxides. The coating is applied by several thermal processes on the titanium base to create a chemical
In a water heater, the sacrificial anode is visible as a rod that slowly erodes over time. The sacrificial anode is made of magnesium, aluminum or a combination of zinc and aluminum. The water in the tank
The cathodic protection system must be designed to provide the required current for each part of the structure for the required lifetime. This requires determining the size, weight, number
Offshore structures include platforms, semi-submerged structures in water or wells, pipelines, and underwater equipment. Offshore steel structures are designed based on two criteria of strength coefficient and strength.
In the oil and gas industry, carbon steel pipelines are used to transport hydrocarbons from jackets to production platforms and storage tanks, and enter refineries through pipelines. Carbon steel pipelines are the safest and least expensive
Underground storage tanks are generally in contact with materials such as soil and sand. The electrochemical reaction between the tank and the surrounding soil (electrolyte) leads to tank
In impressed current cathode protection (ICCP) systems, the current required for protection is supplied from an external source of electrical energy supplied by a DC regulated power
In cathodic protection systems of pipelines or underground structures buried in the soil, the anode used is not in direct contact with the soil. This is because the minerals and chemicals in the soil
