The maximum popping point tolerance for a pressure range of 1000 psig and above is what?

1. 2 psig

2. 3 psig

3. 1%

4. 1 psig

The correct answer is: 1%

For a pressure range of 1000 psig and above, the maximum popping point tolerance is set at 1%. This means that the allowable variation in the pressure relief valve's popping point can be up to 1% of the set pressure. Using this tolerance is critical for ensuring safety and compliance with regulations. At higher pressures such as 1000 psig, even a small percentage can represent a significant amount of pressure, which makes understanding and applying this percentage essential for maintaining the integrity of the system and preventing overpressure situations. This percentage-based tolerance allows for a more standardized approach when dealing with various pressure settings, providing technicians and operators with clear guidelines on acceptable ranges, thus ensuring effective relief mechanisms dependably manage pressure levels.
