Case History---Peer-Reviewed


Several radiators used for locomotive engines, manufactured from a 65/35 copper/zinc yellow brass tube, were found to have leaking problems shortly after manufacture. The radiators were found to experience widespread leaks at varying locations during pressure testing conducted before use in service. A large population of radiators produced during the same production cycle (approximately 80%) experienced leaks. The radiators were returned to the manufacturer as defective. In the months following the discovery of the leaks, a dispute regarding the cause of the leaks arose between the supplier of the yellow brass tube and the manufacturer of the radiator.
