In the course of the pasteurization treatment of milk and dairy products the temperature of the technological process is kept at a constant value. The regulation of the temperature is carred out by means of technological water that comes from certain pools cooled to the temperature of 5 deg C. The water heated in the process of pasteurization is sent back through steel pipes to the pool where it is cooled to the working temperature. The pools for water cooling are fitted with a bundle of pipes made of plain carbon steel that corrode over the time. The protection of pipes against corrosion is possible to be performed in two ways: by use of inhibitors and by cathodic protection. The application of either method depends on a number of factors. It is cheaper to protect new pipes from corrosion using inhibitors, whereas pipes already attacked by corrosion are more efficiently protected against further corrosion by applying the cathodic protection.
