FIVE-YEAR FIELD CORROSION STUDY OF STEEL PIPE TO DETERMINE EFFECTS OF BACKFILL MATERIALS

RESULTS OF A CORROSION STUDY INVOLVING EXPOSURE OF GALVANIZED AND BLACK PIPE SPECIMENS FOR FIVE YEARS IN VARIOUS BACKFILL MATERIALS ARE REPORTED. BACKFILL MATERIALS USED INCLUDED SLAGS, LIMESTONE AND GRAVELS, NATIVE SOIL AND COAL CINDERS. CORROSION OF THE PIPE, CONSIDERING THE VARIABILITY INHERENT IN TESTS OF THIS TYPE, WAS SIMILAR IN ALL BACKFILL MATERIALS EXCEPT COAL CINDERS. ONLY THE CINDERS WERE SERIOUSLY CORROSIVE IN EFFECT, AND NO OTHER BACKFILL USED REACTED IN THIS MANNER. CORROSION OF BLACK PIPE WAS APPRECIABLY GREATER THAN THAT OF GALVANIZED PIPE IN ALL BACKFILL MATERIALS. /AUTHOR/
