Predicting Effects of Corrosion Erosion of High Strength Steel Pipelines Elbow on CO 2
Simultaneously effect of erosion combined with corrosion becomes the most
concern in oil and gas industries. It is due to the fast deterioration of metal as effects of
solid particles mixed with corrosive environment. There are many corrosion software to
investigate possible degradation mechanisms developed by researchers. They are using
many combination factors of chemical reactions and physical process. However effects
of CO2 and acid on pipelines orientations are still remain uncovered in their simulation.
This research will investigate combination effects of CO2 and HAc on corrosion and
erosion artificial environmental containing sands particles in 45o
, 90o and 180o
elbow
pipelines. The research used theoretical calculations combined with experiments for
verification. The main concerns are to investigate the maximum erosion corrosion rate
and maximum shear stress at the surface. Methodology used to calculate corrosion rate
are Linear Polarization Resistance (LPR) and weight loss. The results showed that at
45áµ’, erosion rate is the more significant effects in contributing degradation of the metal.
The effects of CO2 and HAc gave significant effects when flow rate of the solution are
high which reflect synergism effects of solid particles and those chemical compositions
