What is the maximum charge limit for a CNG cylinder at normal temperature?

• A. 110 percent of design pressure
• B. Normal operating range
• C. Design pressure
• D. 150 percent of design pressure

Answer: (C)

The maximum charge limit for a CNG cylinder at normal temperature is the design pressure. This is the maximum pressure that the cylinder is engineered to safely handle during regular operation. Operating at or below this pressure ensures that the integrity of the cylinder is maintained, thereby ensuring safety and compliance with regulations. Charging a CNG cylinder above this design pressure could lead to potential risks, such as structural failure or leaks, as the materials and construction of the cylinder might not accommodate excessive pressure beyond their specified limits. Therefore, adherence to the design pressure is crucial for safe operation and to prevent hazardous situations. The other options relate to different safety measures or parameters, but do not represent the appropriate charge limit for CNG cylinders under normal conditions.
