What is the typical pressure range for non-pressure tanks?

The typical pressure range for non-pressure tanks generally falls between 0 to 0.5 PSI. Non-pressure tanks, also referred to as atmospheric tanks, are designed to store liquids at pressures that are close to atmospheric pressure. This means that the internal pressure does not exceed 0.5 PSI, which is well within the limits for safe storage of various substances while preventing significant vaporization or gas build-up.

These tanks are utilized for materials that do not require pressurization for storage or handling. This ensures safety and reduces the risk of hazardous situations due to over-pressurization. In contrast, tanks operating at higher pressures, such as the other options, serve entirely different purposes and are designed to withstand and maintain those elevated pressures. However, for non-pressure tanks, the critical aspect is maintaining a near-atmospheric pressure to effectively manage the substances contained within.
