A practical diagnostics task of the piping of compressor shops is the evaluation of their operational reliability and safety. For this purpose, weld seams are tested, the presence and sizes of defects are determined and the degree of their danger is evaluated. Another line of diagnostics is the evaluation of the stressed state of pipelines. Together with flaw-detection results, data on the stressed state give quite an objective estimate of pipeline operational safety. It is shown that the monitoring of the stressed state of pipelines with the use of a method based on the evaluation of magnetic properties of a pipe metal allows one to solve completely the problems of improving the reliability of a pipeline system of compressor shops, namely, evaluate the stressed state of pipelines, to detect stress concentration zones, monitor the change of stresses in a construction just during the repair of a pipeline and adjustment of pipeline supports, and optimize the character of the reduction in the stress level.
