Pipe passivation is a method to improve the performance of pipes against chemical corrosion and oxidation through surface treatment technology. Passivation treatment is to form a stable, dense, and non-corrosive oxide layer on the surface of the pipe through coating or electrochemical methods, thereby protecting the pipe surface from damage.

The core mechanism of pipeline passivation is to create a protective oxide layer on the metal surface to prevent the metal from being further corroded. Such an oxide layer can isolate the contact between the metal and the external environment, especially when it comes into contact with water, and can prevent oxidation and corrosion. In the surface treatment of steel pipes, an electrochemical passivation method is generally used, that is, a layer of oxide is applied to the surface of the pipe to resist the erosion of chemical substances such as acids and alkalis.

Pipe passivation has very important applications in industrial manufacturing, construction engineering and other fields. In the field of industrial manufacturing, pipeline passivation can improve the service life of pipelines, reduce the equipment failure rate caused by pipeline damage, and reduce production costs. For example, the oil and gas conveying pipeline can maintain its service life for decades after passivation, greatly reducing maintenance costs. In the field of construction engineering, pipeline passivation can protect the pipeline from being corroded by water rust, thereby greatly extending the service life of the pipeline and reducing the number of repairs and costs.
