Abstrakt:	The problem on pressure relaxation after pressurization in a tubular duct (pipeline) having a damaged section has been considered. The pipeline is filled with a fluid and is placed in the ground. An integral equation describing pressure reduction in the pipeline has been obtained. Exact analytical and approximate solutions of the integral equation have been found. The period of pressure half-recovery after pressurization has been considered as a characteristic parameter determining the pressure drop rate in the pipeline. The period of pressure half-recovery has been analyzed as a function of the geometric parameters of the pipeline, the length of the damaged section, the properties of the fluid, and also the filtration characteristics of the ground.
