What is the popping point tolerance for a pressure range of 71-300 psig?

1. 2%

2. 3%

3. 10 psig

4. 5%

The correct answer is: 3%

For a pressure range of 71-300 psig, the popping point tolerance is set at 3%. This percentage is a critical factor in ensuring the safe and efficient operation of pressure relief devices in boilers and similar systems. The reason this specific tolerance is used is that it provides a balance between safety and operational reliability. A 3% tolerance allows for minor fluctuations in pressure without causing unnecessary activation of safety devices, which could lead to system downtime or excessive wear and tear on components. In engineering and safety standards, maintaining precise pressure control is vital for preventing dangerous conditions. Therefore, 3% is an accepted standard that helps ensure that pressure relief devices function correctly while maintaining operational integrity within the defined pressure range.
