07127 Investigating Ductile Iron Pipelines

This paper presents several case histories where ductile iron pipeline sections have been investigated to ascertain the corrosioncontrol benefits of polyethylene encasement. Investigative procedures, included cell-to-cell potential surveys, side-drain technique measurements, in-situ and laboratory soil tests, pipe-to-soil potential measurements and excavation inspections.

This paper presents several case histories where ductile iron pipeline sections have been investigated to ascertain the corrosioncontrol benefits of polyethylene encasement. Investigative procedures, including cell-tocell potential surveys, side-drain technique measurements, in-situ and laboratory soil tests, pipe-to-soil potential measurements and excavation inspections, were utilized with varied results and reliability. Included are testing results and the location sites of each investigation. These investigations demonstrate the effectiveness of polyethylene encasement as a corrosion control system for ductile iron pipe.

Keywords: Corrosion, Ductile lron Pipe, Polyethylene Encasement, Case Histories, Soil Resistivity, Potential Survey
