The necessity of pipeline pickling treatment: Equipment and pipelines in newly constructed facilities generate a large amount of debris during the manufacturing, storage, transportation, and installation processes. This debris mainly includes: scale, iron oxide rust, silt, welding slag, flux, anti-rust oil, and surface coatings.

The passivation mechanism is mainly explained by the film theory, which suggests that passivation occurs due to the reaction between the metal and an oxidizing medium, during which a very thin, dense, and well-coated passivation film forms on the metal surface. This film exists as an independent phase, typically a compound of oxygen and metal. It acts as a complete barrier between the metal and the corrosive medium, preventing direct contact between them, and thereby halting the metal's dissolution to achieve a passive state and prevent corrosion.

Compared to corrosion during pickling, equipment operation accidents caused by rolling scales, iron oxide rust, mud and sand, welding slag, rust preventive oil, and coatings are more dangerous. As the chemical cleaning leaves a clean metal surface, it allows for faster production of qualified products, resulting in significant economic benefits for the factory that far exceed the cost of the cleaning investment.
