Flexible metallic connectors for stationary containers of 2000 gallon w.c. or less should not exceed what length?

Flexible metallic connectors for stationary containers of 2000 gallon water capacity or less are typically limited to a maximum length of 5 feet. This standard is in place to ensure safety and minimize the risks associated with handling propane. Longer connectors could increase the risk of leaks or failures due to mechanical wear, flexibility, and potential movement of the connector itself.

By keeping the length to 5 feet, it reduces the potential for damage from environmental factors or mechanical strain. Additionally, shorter connectors help maintain a better flow of gas and make it easier to detect any leaks that might occur along the connector's length. Thus, ensuring that the flexible metallic connectors do not exceed this length is crucial for safe and efficient operation of propane systems.
