The pressure gauge on a full nitrogen cylinder should indicate approximately how many psig?

The pressure gauge on a full nitrogen cylinder typically indicates approximately 2000 psig. Nitrogen gas is stored in high-pressure cylinders, and a full cylinder is designed to contain gas at a pressure close to this value. The reason 2000 psig is standard relates to the physical properties and storage requirements of nitrogen.

When nitrogen is stored, it needs to be compressed to a high pressure to ensure adequate supply for various applications, such as in refrigeration systems, purging, or pressure testing. The cylinder is built to safely contain this pressure, thus 2000 psig provides a reliable threshold for operations while ensuring safety and functionality.

The other values provided do not align with the standard pressure of a full nitrogen cylinder. For example, while 1500 psig might be seen in some applications or specific cylinders designed for lower pressures, it is not typical for general use with nitrogen. Similarly, 1800 psig and 2400 psig exceed the normalized pressure levels or are not standard for general nitrogen supply. Hence, the choice reflecting 2000 psig accurately represents the full state of a nitrogen cylinder.
