“…If the pipeline fittings completely fail, the risk of emergency situations is very high. Emergency circumstances in industries where butterfly check valves are used will not only cause harm to personnel and the plant but also adversely affect the environment [16,17]. Due regard for the operating conditions of the device and ensuring the reliability of the structure are two of the most significant tasks when designing safety fittings [18,19].…”

This research aims to increase the reliability and safety of pipeline systems by creating an improved model range of Butterfly Check Valves (BCV). Pipes through which working fluids are transported, parts related to shut-off and control valves, control measuring instruments, fasteners, anticorrosion elements, and other structural components are the main elements that make up pipelines. Fittings can be of different types; BCV refers to protective ones. These devices protect pipelines by disconnecting the working line in the event of a sudden change in the transported fluid parameters (pressure, flow direction), resulting in the failure of the entire system. Based on an analysis of the key requirements for valves, namely reliability, tightness of a closed system, ensuring safe operation, and analysis of existing BCVs, the design of the presented valve was created. Improved overall dimensions and tightness, both in the open and closed states, as opposed to the existing analogs, are distinctive features of the developed design of butterfly check valves. To confirm the results, the authors, using the finite element method, calculated the stress–strain state of the structure under normal conditions and with regard to the maximum temperatures of the working fluid. The reliability indicators of the developed elements were also calculated to confirm their operability. As a result, it was concluded that after the developed valves have passed acceptance tests, the research findings will make it possible to increase the reliability and safety of the valve itself and the entire pipeline system by introducing these structures into enterprises.

Carbon capture and storage technologies play crucial roles in mitigating atmospheric greenhouse gases (GHGs). Pipeline transportation is the primary method of CO2 transportation, making pipeline safety a priority. In this study, Fluent software was used to create a model for annular edge leakage flanges, which significantly differs from the traditional pinhole leakage model. This study aims to examine the impact of CO2 pipeline flow and pressure on the diffusion of gas leaking from the flange and to develop a precise correlation between the diffusion distance and substance concentration. The results indicate that an increase in flow and pressure intensifies the diffusion of the flange leakage. Specifically, for a leakage lasting 96 s at flow rates of 0.7 and 10 m3/h, the diffusion ranges for the 5% concentration alarm threshold are 0.47 and 2.86 m, respectively. Furthermore, at a speed of 10 m/s and a pressure of 0.4 MPa, the diffusion ranges for 5 and 2% alarms are similar, spanning from 0.33 to 0.35 m. This study provides theoretical support and technical improvements to ensure the safe operation of pipelines. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
