Industrial Valves

9Safety and Reliability

9.1 Introduction

In different industries, including oil and gas, valves are essential components of piping systems that regulate and control fluid flow, prevent backflow, and maintain safety. In the offshore industry, various types of valves are used, including ball valves, gate valves, butterfly valves, globe valves, and check valves. Various reasons such as corrosion and mechanical malfunction can result in industrial valves failing to function. This can lead to adverse consequences such as environmental pollution, asset loss, loss of production, or even death. It is true that valves are connected to pipes in order to produce or transport goods. These valves are an essential part of the process, as their failure could halt the entire process. Safety and reliability assurance of industrial valves is such an important topic that has been addressed in past studies. In addition, a subsurface safety valve (SSV) is also installed in the well. In the process of oil and gas production, they monitor the well for abnormal conditions such as an overpressure scenario. This is to prevent blowouts and make sure the well is closed in case of any abnormal conditions. The reliability analysis of SSVs has been a popular topic among researchers. In a separate study, pressure relief valves that are installed on piping and mechanical equipment to relieve the overpressure fluid or gas from the piping and equipment have been subjected to a reliability analysis.
