The assumptions of linear elastic fracture mechanics were accepted. A simple two-dimensional numerical model of multi-layer pipes system consisting of main (functional) pipe and protective layers has been suggested and numerically solved by finite element method. Three basic problems connected with lifetime expectation of two- and three-layer pipe system have been considered and analyzed, namely: question of main pipe material measurements, K – calibration of the pipe system and the problems connected with through cracks in protective layers.
