The multilayer wall structure should be designed in such a way that assures higher reliability of the pipe. On the other hand the existence of interfaces between layers, where the material properties are changed discontinuously, may have a negative influence on their performance. In the contribution two and three layer pipes consisting of main pipe and protective layers are numerically modelled and analysed. It is shown that the crack behaviour depends strongly on the material properties of layers and that proper material combinations of main pipe and protective layers can increase their service lifetime. The results presented can be used to limit the negative influences of the interface and to optimize materials combination of protective and main part of the pipe for practical applications.
