    Han,

    You should include background details with your questions to ensure the community understands how you are defining the problem. There are many reasons for corrosion and the answer you seek may be uncovered by sharing the (L, D, t, etc.) dimensions, materials of construction, flow rates and velocities, corrosion rates and type of failures observed. Also, it is critical to know the composition of the stream including the minor, maybe unintended contaminants.
