What type of gases does a tube trailer typically carry?

A tube trailer is specifically designed to transport compressed gases, including hydrogen and helium. These gases are stored in high-pressure cylinders that are securely mounted on a trailer. The primary function of a tube trailer is to facilitate the safe and efficient transportation of these gases over long distances for various industrial applications, such as in chemical manufacturing or energy production.

While other types of materials may be transported using different specialized containers, tube trailers are not constructed to handle corrosive gases, explosive materials, or liquid hydrocarbons. Corrosive gases typically require vehicles with special lining to prevent damage and leakage, explosive materials necessitate more secure containment to prevent detonation, and liquid hydrocarbons would be transported in tankers designed for liquids. Thus, the distinction of tube trailers is their focus on compressed gases, reinforcing that the correct answer is indeed the type of gases that tube trailers are meant to carry.
