Popis: The current state of guaranteeing operational safety of process pipelines of hydrocarbon materials processing plants and the causes of their failures, which may be attended by explosions and fires and formation of mixtures that produce toxic effect on people and environment, are investigated. It is shown that the methods used for expert assessment of the safety of these objects and the devices for evaluation of their technical state, which are oriented to detection of various existing defects, are not adequately efficient and that it is essential to detect the incipient defects in the metal structure against the background of its stressed-strained state. It is proposed to use, for assessing the technical state and the service life of the process pipelines, a transfer function, i.e., a dynamic mathematical model of the monitored object, which represents its performance properties. The performance properties of a pipeline are expressed through the mechanical, acoustic, magnetic, and electrical properties of the material, which change with change in the stressed-strained state of the pipeline and with initiation and development of defects. Thus, transfer function enables assessment of the current technical state of pipelines.
