4 Axles Carbon Steel Oil Tanker Semi Trailer

HUAYU 4 Axle Carbon Steel Oil Tanker Semi Trailer

The 4 axle carbon steel oil tanker semi trailer uses high-quality carbon steel at 4mm or 6mm thickness for the tank body. This carbon steel tank semi trailer carries a wide range of petroleum products including light fuel, heavy oil, gasoline, diesel, and palm oil. Learn more about what liquids tank semitrailers can transport. Series heating and insulation tanks can also be manufactured for products that need to stay at temperature during transport — heavy oils and bitumen-based products that thicken when they cool are common applications for heated tanks.

HUAYU produces carbon steel tank semi trailers from 20,000L to 90,000L capacity. Aluminum alloy semi trailers are also available for operators who need lower tare weight. The four-axle configuration on this model spreads the loaded weight across more axle lines, which helps meet road regulations in markets with strict axle load limits.

Build Quality and Longevity

HUAYU pays close attention to every construction detail on this carbon steel fuel tanker semi trailer because service life is the metric that matters most to fleet operators. Carbon steel at 4mm or 6mm wall thickness gives the tank body enough material to absorb impact and vibration over years of daily use. Proper maintenance extends service life even further. Thinner walls save weight but reduce the margin for corrosion over the life of the tank. At 4-6mm, operators get a good balance between tare weight and long-term durability.

Discharge System and Safety Testing

Carbon steel oil tanker discharge system

Five API discharge valves are fitted on this carbon steel oil tanker semi trailer. API valves are easier to link with standard discharge pipes at fuel depots, and the reduced tank pressure during discharge improves safety during operation. This is not a minor detail — uncontrolled pressure during fuel offloading is a real hazard, and the API valve design addresses it directly.

Each tank semi-trailer is tested for air tightness and water pressure before delivery: water pressure at 0.036MPa and air pressure at 0.36KPa. These tests confirm that every weld and seal point on the 4 axle carbon steel tank holds under controlled pressure conditions.
