In piping systems, flexible joints can mean connections or elements designed to absorb movement or pressure that can occur in pipes, such as temperature changes or ground movements. This function can help prevent cracks or damage to the pipe system. The use of flexible joints in oil piping aims to maintain the integrity of the pipe system, prevent leaks, and reduce pressure that can damage pipes or other devices. This is critical especially in the oil and gas industry environment which has dynamic operational conditions. The purpose of this study was to find out how to maintain flexible joints and handle damage that occurs to flexible joints in storage tanks at PT X. The results of the study showed that damage of Flexible Joints occurred due to the installation of Motor Operated Valves (MOVs) that did not meet standards and Pressure Safety Valves (PSVs) was not calibrated everyday that experienced corrosion and broken springs due to lack of maintenance. Therefore, routine inspections were needed to prevent damage to the Pressure Safety Valve.
