Analysis of Pipeline Corrosion Causes

With the advancement of industrial technology in China and the rapid development of some chemical refining industries, the corrosion problem of chemical pipelines has become increasingly severe. For example, the corrosion of some oil and gas pipelines not only causes infinite economic losses, but also invisibly affects many products currently on the market Fluorine lined valve factory Due to the increased pressure, it is necessary to adopt some anti-corrosion measures to address the corrosion characteristics of certain pipelines, and carry out protective operations for oil and gas pipelines to ensure their necessary safety.

At present, corrosion of oil and gas pipelines is prevalent throughout the entire process of oil and gas excavation and transportation in the industry. There are many classification methods for corrosion of oil and gas pipelines, generally including classification based on the corrosion environment and classification based on the characteristics and mechanisms of the corrosion process.
According to the corrosive environment, it can be divided into atmospheric corrosion, soil corrosion, seawater corrosion, and chemical medium corrosion. According to the characteristics and mechanisms of the corrosion process, it can be divided into physical corrosion, chemical corrosion, and electrochemical corrosion. Physical corrosion refers to corrosion caused solely by physical dissolution; Chemical corrosion refers to the corrosion caused by pure chemical reactions between pipelines and non electrolytes,
The characteristic is that there is no current surge during the reverse process; Electrochemical corrosion refers to the corrosion caused by the occurrence of electrical currents during the reaction between pipelines and media. The majority of corrosion encountered in oil and gas pipelines is electrochemical corrosion, while chemical corrosion is relatively rare.
Therefore, in some chemical pipelines nowadays, products that use corrosion-resistant materials, such as fluorine lined pipelines, Fluorine lined valve It's a very good choice.
