PIPE SELECTION FOR CORROSION RESISTANCE

Fifty-eight pipe culvert installations were evaluted for durability characteristics and assigned a Pipe Rating (PR) to aid in numerical analysis and correlation with environmental soil and water conditions. Minimum soil resistivity is described as the most important single parameter affecting pipe culvert durability. Resistivity, however, is not reliable enough to use by itself to predict pipe corrosion. Miniumum soil resistivity, pH, total soluble slats, and sulfate content are interdependent parameters affecting pipe corrosion. Test procedures are given to facilitate determinations for minimum soil resistivity, pH, total soluble salts and sulfate content. Total soluble salt content is a more significant factor than any single soluble salt content in predicting pipe material performance. Selection guidelines are given along with examples to aid in pipe material selection. /Author/
