Lining EAA corrosion resistant pipelines is an important measure in transportation pipelines. An EAA lining pipeline is a conveying pipeline suitable for liquid-solid, gas-solid and two-phase flow conveying working conditions, and is currently applied to the fields of conveying petroleum oil sand, ore conveying of metallurgical mines, conveying of chemical media and the like. However, the EAA corrosion-resistant pipe fitting on the market has smooth inner wall, small friction force and large potential energy for transporting objects, so that the flow velocity inside the pipeline is large, noise is caused, and the work and daily life of people are influenced. In a pipeline system, corrosion is defined as: depending on the particular pipeline environment, chemical reactions, electrochemical reactions, and microbial attack that occur in all metallic and non-metallic materials of the pipeline system can lead to damage and loss of pipeline structure and other materials. In addition to direct damage to the material from corrosion, pipe damage caused by corrosion products can also be considered corrosion damage. Whether the pipeline corrosion will spread or not depends on the erosive power of the corrosive medium and the corrosion resistance of the existing pipeline material. The temperature, concentration of corrosive media, and stress conditions all affect the extent of corrosion of the pipe.
