Remove impurities：
Acid pickling and passivation can effectively remove impurities such as oxide scale, rust, and pollutants on the surface of pipelines, such as oil stains, welding residues, rust, and dust.
This not only reduces the roughness of the inner wall of the pipeline, but also improves the smoothness and surface quality of the pipeline, providing a good foundation for subsequent use.
Improve corrosion resistance：
Through acid washing, oxides and impurities on the surface of the pipeline can be removed, thereby increasing the contact area between the pipeline and the medium and improving heat and mass transfer performance.
The passivation process forms a uniform and dense oxide film on the surface of the pipeline, which can effectively block the entry of external oxygen and moisture, reduce the corrosion rate, and improve the corrosion resistance of the pipeline.
Especially in stainless steel pipelines, acid pickling and passivation can remove the oxide layer and welding residue that may form during the welding process, further improving the corrosion resistance and compressive performance of the pipeline.
Improve pipeline performance：
After acid pickling and passivation treatment, the surface of the pipeline becomes smoother, reducing fluid resistance in the pipeline and improving fluid transmission efficiency.
Meanwhile, due to the improvement of surface quality, the wear resistance of the pipeline has also been enhanced, extending its service life.
Easy to operate and cost-effective：
Compared to other surface treatment methods, the operation process of acid pickling and passivation is relatively simple, without the need for complex equipment and processes, reducing treatment costs.
The processed pipeline does not require additional cleaning and drying treatment, saving time and resources.
