    Understanding failures and corrosion damages in flowlines containing more than one phase are important in oil, gas and petrochemical industries. One major controlling parameter in these damages is the nature of the fluids: water cut %, level of corrodants, chlorides, CO2, H2S and the similar. Another controlling parameter is the flow rate/regime. By reviewing some of the pertinent literature, it was not clear whether the location of corrosion damage is related by some way to flow regime or not. For example: localized corrosion of carbon/low alloy steel at the oil/water interface, in a two phase system, and its possible mechanism is not clear. I would appreciate if you can share your thoughts in this issue…
