Abstract

C5 is a hydrogen sulfide containing media. Corrosion behavior of liquid level gauge pipe was investigated with cross section morphology observation and element analysis in this study. The material of the pipe is 20# steel with massive ferrite and lamellar pearlite. The Vickers hardness of the pipe cross section is 130-150HV. The corrosion product is loose and polyporous with many cracks. The boundary between corrosion layer and metal is generally straight. The corrosion type belongs to uniform corrosion. O and Fe have opposite distribution in the corrosion products layers. Iron-sulfur compounds were observed with SEM-EDS analysis, and S content is up to 2.87%. S mainly distributed at the corrosion products layer, especially at the boundary between the corrosion layer and the matrix metal.
