Case 2. Condenser pipe
In the condenser pipe of an air conditioning system designed in stainless steel 1.4301, the first leak was observed after just a couple of months service [11]. The water was a mixture of ground water and drinking water with 120 mg/l chloride. Apart from some short stagnant periods of operation the system had been generally flowing continuously with 1 m/s. The maximum temperature was 30 ºC.
