The suitability of carbon steel as piping material servicing industry wastewater is questionable. Carbon steel pipelines suffer various types of corrosion depending on the media transported. Although top of line corrosion (TLC) is rare, few investigators were able to offer a clear mechanism for its cause.
The case presented here is in the petrochemical industry in wastewater services. A 40-meter carbon steel pipeline with 203.2-mm outer diameter and 6.35-mm thickness operated under a batch flowrate only twice a day at a rate of 1.9 m/s. A maximum corrosion rate of 500 mpy was determined under the given operating and process conditions. Results of light optical microscopy, metallugraphy and
