CORROSION OF STEEL AND TWO TYPES OF CAST IRON IN SOIL
OF THE THREE PIPE MATERIALS, STEEL AND GRAY AND DUCTILE CAST IRONS, STEEL IS THE BEST FOR A GIVEN THICKNESS WHERE BURIED BARE IN SOIL, ALTHOUGH GRAY CAST IRON IN LARGER COMMERCIAL SIZES IS THE ONLY ONE NOT REQUIRING AN EXTERNAL COATING FOR A SERVICE LIFE OF 50 YEARS. THE UNDERGROUND PITTING CORROSION STUDY SUBJECTED NATIONAL BUREAU OF STANDARDS DATA TO AN INTERPRETIVE TECHNIQUE DEVELOPED AT THE U.S. BUREAU OF RECLAMATION. PIT DEPTH RELATIONS GIVEN AS TWO TYPES OF EQUATIONS HAVE BEEN ESTABLISHED FOR THE THREE MATERIALS. DUCTILE CAST IRON, MADE ACCORDING TO MANUFACTURERS SCHEDULE, HAS ABOUT THE SAME SERVICE LIFE AS STEEL IN SEVERELY CORROSIVE SOIL, EVEN THOUGH ITS PITTING RATE IS GREATER THAN EITHER STEEL OR GRAY CAST IRON. /AUTHOR/
