Also known as MC-331 (or equivalent) cargo tanks. These tank trucks have pressures typically between 100 to 500 psi with typical capacities between 3,000 to 11,000 gallons. High pressure cargo tanks have a single, steel compartment.
Cryogenic Tank Trucks
Also known as MC-338, TC-338, or SCT-338 (or equivalent) cargo tanks. These tank trucks have pressures that can be less than 25 and up to 500 psi, and capacities of 8,000 to 10,000 gallons. These trucks have well-insulated aluminum or steel tanks with vacuum-sealed shells.
Low Pressure Chemical Tank Trucks
Also known as MC-307 or DOT/TC-407 (or equivalent) cargo tanks depending on the specifications to which they were built. These tank trucks typically have a pressure of 25 to 35 psi, with typical capacities of 5,500 to 7,000 gallons. Most have a stainless steel, mild steel, or aluminum tank and some may have a rubber lining, rubber coating, or polymer coating.
Nonpressure Cargo Tank Trucks
Also known as MC-306 or DOT/TC-406 (or equivalent) cargo tanks depending on the specifications to which they were built. New tanks are constructed of aluminum or steel, but older tanks are made of steel.
Corrosive Liquid Tank Trucks
Also known as MC-312 or DOT/TC-412 (or equivalent) cargo tank trucks depending on the specifications to which they were built. These typically have a pressure range of 35 to 55 psi and may have a much higher maximum allowable working pressure. Typical capacities are 3,300 to 6,300 gallons. They are constructed of aluminum, mild steel, stainless steel, and fiberglass reinforced plastics, lined with rubber or polymer. The outer jacket may be aluminum or stainless steel and often covers a layer of insulation.
