What is the delivery pressure of high-pressure cylinders?

High-pressure cylinders are designed to store gases under significant pressure, typically ranging from about 2000 to 3000 psi or more, depending on the type of gas and the specific application. However, when discussing the delivery pressure of high-pressure cylinders, especially in applications such as gas delivery systems for cutting and welding, the typical range is usually much lower than the storage pressure.

The correct answer, 50-55 psi, aligns with standard operating pressures for many equipment setups that utilize high-pressure gas cylinders. This pressure range is commonly used because it is sufficient for most applications while ensuring the safe and efficient use of the gas being delivered. It allows the equipment connected to the cylinders to function effectively without being overwhelmed or damaged by too high a pressure.

In contrast, the other values provided suggest delivery pressures that are either too low or too high for standard high-pressure gas applications. Lower pressures might not adequately support the necessary flow rates for certain operations, while higher pressures could lead to safety hazards and inefficiencies when connecting to standard equipment designed for lower pressure systems.
