Answer :
Final answer:
Turbine pumps require relief valves on the discharge line to protect against overpressure by releasing excess pressure safely, thereby ensuring both equipment safety and compliance with safety procedures.
Explanation:
Turbine pumps must be equipped with a relief valve on the discharge line to protect the pump from overpressure conditions that can occur due to various reasons such as loss of heating or cooling, mechanical failure, or other process disturbances. The purpose of pressure relief valves is to act as a safety device, ensuring that the pump and associated equipment are not subjected to pressures that exceed their design limits, which could result in equipment failure or even catastrophic accidents. In designing relief systems, it is vital to consider the risks of exposing personnel to chemical hazards, the support for long stretches of discharge piping that might be subjected to forces from material flow, and the potential for underestimating pipe sizes due to two-phase flow separation, which might lead to higher pressure drops and valve ruptures.
Additionally, the integration of emergency vent headers that release on the plant roof, the use of fireproof insulation in conjunction with standard relief systems for flammable materials, and the careful inclusion of safety valves in P&ID designs are critical aspects of ensuring plant safety and compliance with safety codes and procedures.
