Which type of cargo tank is typically oval-shaped and carries gasoline and flammable liquids?

The oval-shaped cargo tank designed specifically for carrying gasoline and flammable liquids is commonly classified as a non-pressure liquid cargo tank. This type of tank is suitable for transporting liquids that are not under significant pressure, making them ideal for materials like gasoline, which can be hazardous but does not require high-pressure containment.

Non-pressure liquid cargo tanks are typically built with structural features that facilitate the safe transport of liquids while minimizing the risk of spills and leaks. Their design ensures stability and reduces potential hazards associated with flammable liquids, such as fire or explosion.

In contrast, low-pressure chemical cargo tanks are designed for the safe transport of chemicals under low-pressure conditions, but they do not specifically focus on gasoline or flammable liquids. High pressure cargo tanks are intended for transporting gases and liquids under high pressure, which is unsuitable for flammable liquids like gasoline that can vaporize easily under increased pressure. Cryogenic liquid cargo tanks are built for the transport of extremely cold liquids, such as liquefied natural gas, making them unsuitable for gasoline. Thus, the other categories of tanks serve different purposes that do not align with the requirements for carrying gasoline and similar flammable liquids.
