This paper examines the operability of the Orenburg-Zainsk main gas pipeline, which has been in operation since 1971 and has various general defects, as well as specific defects such as internal corrosion-induced delaminations and blisters of various geometric shapes. The design parameters of the gas pipeline section and the characteristics of the pipe metal have been studied. Hydraulic tests were performed on the pipe fragments in the form of sample barrels to determine the load-bearing capacity in order to evaluate the operability of the gas pipeline. There were three types of sample barrels: those made from pipes with internal blistering and delamination, from pipes with invisible defects, and from emergency stock pipes. A cyclic test was performed on one sample according to the developed method. The theoretical analysis of the load-bearing capacity of the gas pipeline was performed according to the accepted design model.
