Corrosionpedia explains Petroleum
Petroleum is also known as crude oil and is refined through the process of fractional distillation. Fractional distillation separates petroleum into its constituent fuels that are used in various capacities around the world. These capacities range from powering vehicles to warming homes. Pipelines and vessels used to transport or store petroleum must be closely monitored for corrosion as petroleum contains moisture, hydrocarbons and other corrosion-initiating substances.
