PREDICTION METHOD FOR CORROSION RATE OF EMBEDDED PIPE

摘要

PROBLEM TO BE SOLVED: To simply predict the depth of corrosion of a cast iron pipe embedded in the ground.;SOLUTION: The depth of corrosion of a cast iron pipe embedded in the ground is indicated by y=K×exp(A+B+C)×T^0.4, (y: a prediction value of the depth of corrosion [mm], K: a constant; A: a constant, B is a constant decided by surface resistant [Ω.cm²] producing between the surface of a cast iron pipe and soil in which the cast iron pipe is embedded, C: a constant fixed with whether the soil is sand or not, and T: embedded period [year].).;COPYRIGHT: (C)2003,JPO
