What rated service pressure is required for cascade storage cylinders?

Answer: C — 3,600 psig

The rated service pressure required for cascade storage cylinders is 3,600 psig. This pressure rating is essential because it indicates the maximum pressure that these storage cylinders can safely handle while ensuring the integrity and safety of the system. Cascade systems are designed to efficiently manage the filling, storage, and dispensing of compressed natural gas, and having a high service pressure allows for a greater volume of gas to be stored and transported effectively. Understanding this specification is critical for operators to maintain safety standards and prevent potential risks associated with gas containment failure. Adequately rated cylinders contribute to the overall efficiency and reliability of the fueling system for CNG vehicles.
