What type of products are typically transported in non-pressure liquid cargo tanks?

Non-pressure liquid cargo tanks are specifically designed to transport various types of liquids that do not require pressurization for safe transport. Liquid food products typically fall into this category, as they are often transported in bulk quantities and must be kept at specific temperatures and conditions. These tanks have features that prevent contamination, preserving the quality and safety of edible goods during transport.

While pesticides can sometimes be transported in tanks, they often have specific requirements that may necessitate other types of containers or pressure systems depending on their chemical properties. Compressed gases generally require pressure vessels that can withstand elevated internal pressures, making them unsuitable for non-pressure tanks. Heavy metals, being solid or potentially toxic materials, would not be transported in liquid tanks but rather in specialized containers designed to handle solid waste or hazardous materials. This makes liquid food products the most appropriate choice for transport in non-pressure liquid cargo tanks.
