Ensuring the design indicators of the transported gas quality is one of the most important tasks to be solved for the uninterrupted, efficient and reliable supply of natural gas to consumers. In this regard, the article considers the results of research on methods and technologies for diagnosing technical means for drying pipelines after hydraulic tests, filling the gas pipeline with nitrogen for safe reception of natural gas as well as pipeline conservation. A technique for diagnosing the nitrogen module by the mechanical impedance method has been developed, which makes it possible to assess the dynamics of changes in operating parameters for controlling the drying process of the linear part of gas pipelines and technological pipelines of compressor stations.
