COMPREHENSIVE EVALUATION OF ALUMINIZED STEEL TYPE 2 PIPE FIELD PERFORMANCE (DISCUSSION AND CLOSURE)

Results of 30-year field tests in 14 states, conducted by Armco on Aluminized SteelTM Type 2 and galvanized steel culvert pipe, have revealed a consistent and pronounced superiority of aluminized steel. The results were tabulated from 54 test sites where the materials were usually exposed together under climatic conditions ranging from very wet to very dry. Comparison of the field performance of the two materials revealed considerable differences in the basic coating corrosion-control mechanism. The aluminized steel coating imparted significantly better resistance to general corrosion and localized perforation. Analyses of pipe condition and environmental factors at every site resulted in usage guidelines for both materials. The results for aluminized steel indicated tolerance for substantially more severe environmental conditions. The technique by which the guidelines were derived has promise for predicting service life for the two materials as well. In the discussion and closure, Summerson and the authors debate the need for more field test data in terms of longer exposure times and in a broader range of environmental conditions.
