If a discharge pipe is used on a safety valve, it must be of what size?
Smaller than the safety valve
Same size as the safety valve
Larger than the safety valve
Half the size of the safety valve
The correct answer is: Same size as the safety valve
The requirement that a discharge pipe must be the same size as the safety valve is essential for ensuring the efficient operation and effectiveness of the safety valve. This specification allows for the maximum discharge capacity of the valve to be utilized. If the pipe is too small, it can create a restriction that may prevent the valve from operating properly, potentially leading to an unsafe buildup of pressure. Additionally, maintaining the same diameter prevents back-pressure from developing in the system, which could cause the safety valve to malfunction. A proper-sized discharge pipe facilitates the safe and unobstructed release of steam or pressure, aligning with safety standards and regulations. This design consideration is crucial in preventing potential hazards associated with pressure vessel systems.
