When underground laying, the pipeline bends in accordance with the terrain under the influence of its own weight and an overlying layer of soil. The article provides calculations of the radius of curvature of the pipe and its comparison with the allowable one. Thus, it can be seen from the above calculations that the obtained radii are less than the minimum permissible radius of curvature. Calculations showed that the radii in the horizontal and vertical planes are acceptable.
