What defines a Portable Tank in the context of CNG?

A Portable Tank, in the context of Compressed Natural Gas (CNG), is defined as a large tank specifically designed for the temporary transport of liquids or gases. This definition is important as it highlights the intended function of these tanks, allowing for safe and effective transportation of CNG in various settings, such as during deliveries or storage at temporary locations.

The design and operational characteristics of Portable Tanks enable them to be moved and used as needed, unlike stationary installations, which are fixed in place for long-term storage or use. The emphasis on temporary transport distinguishes these tanks from others that are meant for permanent installation. Additionally, while lightweight materials may enhance maneuverability, the essential defining feature is their purpose for transporting CNG rather than solely their material composition.
