Trailer tanks are large - capacity containers mounted on trailers, designed for transporting liquids and gases. These tanks come in different shapes, sizes, and materials, such as stainless steel, aluminum, or composite materials, depending on the nature of the cargo. They are equipped with fittings, valves, and pumping systems for easy loading, unloading, and transfer of goods. Trailer tanks are used in various industries, including oil and gas, chemicals, and food and beverage, for the bulk transportation of products. Safety features, like leak - proof seals, emergency shut - off valves, and pressure - relief devices, are incorporated to ensure the safe transit of hazardous or non - hazardous materials.
