Abstract: The S-type pipeline is used in the complex terrain during transportation, and different degrees of erosion corrosion will be formed at the elbows of the upstream and downstream, resulting in safety risks. In order to analyze the influencing factors of corrosion and establish the S-shaped pipeline corrosion model, the Fluent module was built on the Workbench platform of ANSYS to study the corrosion models under different influencing factors, create data transmission, and then study the relationship between various factors and erosion rate after the fluid flows into the bend. The results show that the scour corrosion of S-shaped pipeline is affected by many factors, especially the scour corrosion at the downstream elbow. Appropriately reducing particle diameter and mass flow rate, and increasing the ratio of pipe diameter to bend diameter can slow down the corrosion and reduce the corrosion area. The research can provide theoretical basis for safe and stable operation of pipeline corrosion.
