An acid tanker is a specialized vehicle designed for the transportation of highly corrosive acidic liquids. The tanker's tank is constructed from materials that can resist acid attacks, such as stainless steel alloys with high corrosion resistance, or lined with acid - resistant polymers. Safety features are comprehensive, including double - walled construction to prevent leaks, pressure - relief valves to manage internal pressure generated by acidic reactions, and leak - detection sensors for early warning. The tanker also has secure fittings and valves that are resistant to acid corrosion, ensuring safe loading, unloading, and transit of acidic chemicals. Compliance with strict regulations for hazardous material transportation is essential to prevent environmental contamination and ensure the safety of personnel involved in the handling and transport of acids.
