How often shall gauges be replaced?

Explanation:
Gauges can drift and lose accuracy over time due to wear, corrosion, and exposure to system conditions. Replacing them on a set schedule keeps readings reliable for inspections and testing, which is crucial for recognizing real pressure changes or problems in the system. Five years is the standard interval, balancing accuracy with practicality. Choosing one year would be unnecessarily frequent, three years isn’t the common standard, and ten years risks accumulating too much drift before replacement.
