FIELD: pipe line engineering. SUBSTANCE: pipe line is laid on three- connected supports on stable portions above and under the slide slope. On the slide slope the pipe line is laid on one-connected and two-connected supports. The compensator underlies the slide slope. A dependance of the rigidity performance of a pipe on a maximum distance between the adjacent support for any portion of the slide slope is defined by a relationship presented in the invention description. EFFECT: enhanced reliability. 4 dwg
