Abstract
The tees and laterals of outlet oil vapor pipelines of coke drum in Shanghai Petrochemical Company suffered from severe erosion.Analyses indicated that the erosion corrosion resulted from the combined effect of turbulent erosion and high-temperature sulfur corrosion.It is suggested that the materials should be upgraded to 1Cr5Mo steel to solve this problem.
