Soil Corrosion Data for Corrugated Steel Pipe






National Corrugate Steel Pipe Association Chart

To provide quick reference to coating selection on corrugated steel pipe, the National Corrugated Steel Pipe Association has produced the following chart. Contained in the chart is the anticipated service life of galvanized coatings based on soil pH and resistivity. This chart is applicable to all uses of hot-dip galvanized steel in soil and can be used as a guide to anticipate its service life in soil.
