In the present paper there were considered different methods of the pipelines stress-deformed state calculations. Pipe, shell and solid methods were compared. It was shown that using of pipe finite elements in case of the compound bending leads to significant error in maximum stress prediction. The prospectivity of using of the shell finite elements in case of the compound bending calculation was established.
