Relief devices are safety mechanisms designed to prevent excessive pressure buildup in systems such as boilers, pipelines, and storage tanks. They automatically release pressure when it exceeds a predetermined limit, ensuring the system operates safely and efficiently. Common types of relief devices include pressure relief valves and safety valves. These devices are crucial in various industries, including oil and gas, chemical manufacturing, and power generation. By maintaining safe pressure levels, relief devices help protect equipment, prevent accidents, and ensure compliance with safety regulations. Regular maintenance and testing of these devices are essential for their reliable performance.
