Taking into account the geographic features and operating conditions of the objects of the main pipeline transport remote from the places where the maintenance personnel is living permanently, and in order to ensure safe operation of these objects it is required to regularly inspect and diagnose the buildings and structures included in the complex of the main pipelines along with the pipe products, valves and equipment. Based on the experience gained from the regular inspections of oil pumping station buildings as part of the main oil pipelines and oil product pipelines, which were performed during the period of 2014–2017, an analysis was made related to the effect of the service life on the rate of damage and defects occurrence. In addition, the analysis was made concerning the state of the individual structures and buildings in general. Sampled statistical data are given concerning the defectiveness of individual structures. It is established that the defects occurred in connection with the features of the adopted design decisions (structural defects), and the defects of the construction origin are mainly manifested during the first 10 years of operation. Upon expiry of this period, the occurrence of defects associated with the operating conditions is most likely. For the constructions of various type the list of the characteristic and the most dangerous defects that reduce the category of buildings technical condition is defined. These regularities allow us to reasonably assign the terms and the scope of the required inspections.
