What is the minimum rated service pressure for cascade storage cylinders at 70 degrees Fahrenheit?

The minimum rated service pressure for cascade storage cylinders at 70 degrees Fahrenheit is established to ensure safe and efficient storage and transport of compressed natural gas (CNG). This pressure rating is crucial as it helps to safeguard against potential risks associated with the storage of gases under high pressure.

In the context of CNG storage, 3,600 psig is the standard pressure that provides adequate safety margins, allowing the cylinders to operate effectively under both normal and fluctuating temperature conditions. This rating is derived from industry standards that address the strength and reliability of the materials used in the construction of storage cylinders, ensuring that they can handle the stress associated with high-pressure gas storage without risk of failure or leakage.

By setting a minimum rated service pressure of 3,600 psig, regulatory bodies ensure that the storage systems can accommodate temperature variations and provide a safe working environment for technicians and operators handling CNG.
