Service life of a polymeric composition (a type covering «sandwich») in contact with water is estimated at temperature 20…60 °С. The estimation was made on the basis of definition of diffusion characteristics of water into a polymeric composition (a type covering «sandwich»). The diffusion characteristics of a water into a covering and its components are analyzed. The period of accident-free work (without corrosion) of a epoxy covering under condition ofcontinuous contact with water at temperature 20…60 °С is 6…12 years.
