Abstract
The purpose of the study was to improve the reliability and safety of gas pipeline operation through a detailed analysis of modern technical solutions, innovative technologies, and effective control methods. Modern technical and organisational solutions for ensuring the safety of pipeline gas transport at industrial facilities were analysed. It was established that the highest efficiency is demonstrated by the combination of automated control systems, the use of corrosion-resistant materials, and network segmentation using emergency valves. The technical characteristics of the main pipe materials were analysed: in particular, austenitic stainless steel can withstand up to 2.5 megapascals at a temperature of +120°C, which makes it suitable for main gas pipelines; polyethene (PE100) provides operation at a pressure of up to 1.0 megapascals and a temperature of +40°C, which is suitable for underground gas supply. Sensor types were also considered, in particular, methane gas analysers with an accuracy of ±2 particles per million and a reaction time of up to 5 seconds, which is especially effective for polymer pipes. The article summarised the experience of using intelligent devices for in-tube diagnostics that can detect mechanical defects without stopping transportation. Special attention was paid to the use of unmanned aerial vehicles: multicopters with thermal imagers and cruise drones with a laser scanner allow quickly examining hard-to-reach areas up to 50 km long. It was concluded that it is necessary to integrate these solutions into a comprehensive maintenance system. The results obtained can be used to develop and implement modern integrated safety systems at industrial facilities, which will help reduce accidents and improve the reliability of gas transmission infrastructure
