The current state of ensuring the operational safety of technological pipelines of plants for the processing of hydrocarbon raw materials, the reasons for their failures, which can be accompanied by explosions and fires, the formation of mixtures that have a toxic effect on people and the environment. Insufficient efficiency of the methods and means for assessing their technical state, which are aimed at identifying already developed defects, the need to identify incipient defects in the metal structure against the background of a stress-strain state, are shown. It is proposed to use the transfer function, a dynamic mathematical model of the controlled object, reflecting its operational properties, when assessing the technical condition and resource of technological pipelines. The operational properties of the pipeline are expressed through the mechanical, acoustic, magnetic and electrical properties of the material, which change with a change in the stress-strain state of the pipeline, the initiation and development of damage. Thus, the transfer function makes it possible to assess the current technical condition of the pipeline.
