A road trailer containing multiple pressure vessels into a single unit is called

• A. Tank trailer
• B. Box trailer
• C. Tube trailer
• D. Cryogenic trailer

Answer: (C)

The main concept here is how industrial gases are transported in different trailer configurations. A road trailer that groups several cylindrical pressure vessels into one unit is designed to move multiple high‑pressure gas cylinders together, and this setup is commonly called a tube trailer. The term “tube” reflects the long, tube‑like vessels carried on the trailer, all combined into a single unit for transport. This fits because it’s not just a single tank, but a collection of pressure vessels arranged on a trailer to form one load. By contrast, a tank trailer carries one large bulk tank, a box trailer is a generic enclosed cargo trailer, and a cryogenic trailer carries refrigerated liquid gases in insulated tanks rather than multiple high‑pressure cylinders.
