Study of corrosion material accumulated on the inner wall of steel water pipe

The purpose of this study is to identify the chemical composition of corrosion material accumulated on the inner wall of a mild steel “water pipe”, and the iron species present. It will be shown that the material accumulated is predominantly derived from in situ iron corrosion processes rather than from the sedimentation of particles introduced into the water distribution system. The dominant iron species found was Fe(III) – >90%, with concentrations of Fe(II) and Fe free+amorphous (free and amorphous Fe) being
