Underground Hot Water Piping Corrosion and Leakage

A large condominium project experienced extensive leakage in an underground hot water piping system, which interconnected a complex of buildings. The piping was 2-inch diameter copper with external insulation that had been poured in place. The leak locations were observed to be at elbows or transitions with fittings. A metallurgical failure analysis indicated that the failures were due to erosion-corrosion damage on the internal pipe surfaces. It is likely that the piping system was operated above the design temperature and flow rate conditions for several years prior to the failures. The operating parameters were reset to the design requirements and the piping system was replaced.
