Stresses are determined which occur in pipes of the gas pipeline when the repair column is fitted over the pipes. Flexing shapes and stress values are found for the model of the pipeline section under repair depending on locations of the column elements. Forces occurred in hooks of trolley hangers of pipelayers are defined in the static case.
