Aqueous ammonia tanker trucks are specialized for transporting ammonia dissolved in water, a substance with corrosive and potentially hazardous properties. The tanks of these trucks are constructed from materials that can resist ammonia's corrosive effects, such as stainless steel or lined with ammonia - resistant polymers. They are equipped with safety features like leak - detection systems, pressure - relief valves, and proper ventilation to handle the release of ammonia gas. Aqueous ammonia tanker trucks must comply with strict regulations for transporting hazardous substances, ensuring the safe delivery of ammonia for applications in agriculture, refrigeration, and chemical manufacturing.
