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.

对烃类材料加工厂工艺管道运行安全保障现状及故障原因进行了调查，这些故障可能伴随着爆炸和火灾以及形成对人和环境产生毒性影响的混合物。结果表明，用于对这些物体的安全性进行专家评估的方法以及针对检测各种现有缺陷的技术状态评估装置的效率不够高，因此检测初期缺陷至关重要。在其应力应变状态背景下的金属结构中。为了评估工艺管道的技术状态和使用寿命，建议使用传递函数，即被监控对象的动态数学模型，这代表了它的性能特性。管道的性能特性是通过材料的机械、声学、磁学和电学特性来表达的，这些特性随着管道应力应变状态的变化以及缺陷的产生和发展而变化。因此，传递函数能够评估管道的当前技术状态。
