Abstract Text | This talk presents the results of case histories of some of the oldest installations where gray cast iron and/or ductile iron pipelines were installed using polyethylene encasement as a means of external corrosion control. Investigative procedures included soil testing, excavation and physical inspection of exposed pipe sections and laboratory testing of the polyethylene material. Included are the testing results and the location of each investigation. The investigations demonstrate the effectiveness of polyethylene encasement along with its most up-to-date generation V-Bio enhanced polyethylene and how this will allow a pipeline designer to implement a safe and sustainable design. Also, the audience will be introduced to the Design Decision Model (DDM). |
