Pressure Relief Devices (PRDs) 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 integrity of the system and protecting against potential failures or explosions. Common types of PRDs include relief valves, safety valves, and bursting discs. These devices are crucial in various industries, including oil and gas, chemical manufacturing, and power generation, where managing pressure is essential for safe operations and compliance with regulatory standards.
