Abstract	During the operation of a high-strength steel compressible gas pipeline, the corrosion rates in the strong turbulence position near the inner-wall of the pipe are higher than average corrosion rates. These changes lead to internal corrosion defects. Researchers constructed a finite-element pipe model based on the working conditions of an X70 pipeline in the West-to-East Natural Gas Transmission Project. The resulting prediction method provides a more targeted on-site inspection of long-distance gas pipelines made of high-strength steel.
