N2 - Flow assisted corrosion (FAC) is a problem of pipeline systems that handle high flow rates and strong direction changes. In the present investigation, FAC was tested on carbon steel exposed to the NACE 1D-196 environment by means an experimental pipe loop. As the exposure time increased, corrosion products formed a mixture of oxides, sulfides, and an apparent sulfate (rhombohedral mikasaite Fe2 (SO4)3), which was found in greater proportion and appeared to have a significant effect on decreasing corrosion rate. Transmission electron microscopy and x ray diffraction patterns seemed to confirm the presence of a sulfate and some oxides as the major chemical species contained in the corrosion products.
