Abstract

In the operation of some structures, particularly in energy or chemical industry where pressurized pipeline systems are employed, certain unexpected critical situations may occur, which must be definitely avoided. Otherwise, such situations would result in undesirable damage to the environment or even the endangerment of human life. For example, the occurrence of such nonstandard states can significantly affect the safety of high-pressure pipeline systems. The following paper discusses basic physical prerequisites for assembling the systems that can sense loading states and monitor the operational safety conditions of pressure piping systems in the long-run. The appropriate monitoring system hardware with cost-effective data management was designed in order to enable the real-time monitoring of operational safety parameters. Furthermore, the paper presents the results obtained from the measurements of existing real-time safety monitoring systems for selected pipeline systems.

Summary

Introduction

The operational loading for which a real structure is designed can differ from the real loading in many cases. In the case of pressurized pipelines (e.g., gas transit systems, oil pipelines, or other liquid pipeline systems under pressure), the piping systems may be subjected to a quasi-static loading or of a predominantly variable loading due to a varying pressure of the operating medium. In the case of compressor stations, for instance, or the geometrical-fluid ratios in the closed side branches, the setting of the compressor’s operating point can cause dynamic phenomena, i.e., pipeline vibrations, as pointed out in [3,4,5,6,7,8,9]. Other changes occurring in the operation of piping systems may occur in the subsoil of the pipeline
