Highway Carriers

Question 0

These tanks transport gases that have been liquefied through compression, and the contents must remain under pressure to maintain their liquid state. To withstand this internal pressure, ________ tanks have rounded heads. In addition, the top two thirds of the tank is highly reflective or painted white. Often, the entire tank is highly reflective paint it white.

Answer 0

Pressure cargo tanks

Question 1

These tanks are circular in cross-section, with flatheads. Thanks may slant noticeably downward toward the unloading piping located either at the center or rear of the tank. In addition, these tanks have rollover protection around the area of the manhole assembly.

Answer 1

Low pressure cargo tanks

Question 2

These tanks have elliptical cross-sections and flatheads. In addition, these tanks are usually compartmented, with each compartment having it’s own manhole assembly. These tanks also have rollover protection (a catwalk) running the length of the tank.

Answer 2

Non-pressure cargo tank

Question 3

These tanks are often smaller in diameter than other cargo tanks. Most have visible stiffening rings running vertically around the tank for added strength. These tanks have rollover protection around the manhole and fittings, and may be equipped with a splash protection around the manhole assembly.

Answer 3

Corrosive Liquid cargo tanks

Question 4

These tanks are specifically designed to carry gases that have been liquefied through temperature reduction. These liquids must remain extremely cold to maintain liquid state. These tanks are heavily insulated, giving them a bulky appearance. They have circular cross-sections and rounded heads, though the heavy insulation can make the heads appear flat. Discharge and fill piping, valves, and pumps are usually located within a cabinet or station at the center or rear of the tank.

Answer 4

Cryogenic liquid cargo tanks

Question 5

These carriers contain from 2 to 20 long, thin cylinders that are permanently mounted on a semi trailer. The cylinders range from 9 to 48 inches in diameter. These carriers are designed to carry gases under pressure; they do not carry liquefied gases.

Answer 5

Tube trailers

Question 6

The most distinguishing characteristics about this vehicle are its large, sloping, V-shaped unloading compartments located at the bottom of the trailer and it’s rear-mounted air compressor. These vehicles carry materials such as fertilizers, oxidizers, and plastics.

Answer 6
