The three-axle carbon steel tank semi-trailer is classified as a vehicle for the transport of hazardous chemicals; it consists of a carbon steel tank body, chassis frame, three-axle assembly, suspension system, braking system, and various safety accessories. The tank body is manufactured using fully automated welding, hydraulic pressure testing, and anti-corrosion coating processes. Internally, it is equipped with surge baffles, while externally, it features safety systems-including European-standard manhole covers, emergency bottom valves, and vapor recovery units-designed specifically for the large-scale transportation of refined fuels and industrial oils. Furthermore, the vehicle is required to comply with national standards such as GB 18564, as well as applicable regulations governing the transport of hazardous chemicals.
Three-axle carbon steel tank semi-trailer Key Features
1. Robust Structure, Reliable Load-Bearing Capacity
The tank body is constructed from 4.5–6 mm thick Q235B/Q345R carbon steel, with end caps measuring 6–8 mm; this design ensures high structural strength, impact resistance, and deformation resistance.
Featuring a multi-compartment internal design (2–6 compartments), the vehicle allows for the simultaneous transport of various petroleum products; internal baffles minimize liquid surging, thereby enhancing driving stability.
The tri-axle chassis ensures uniform axle load distribution (13 tons per axle), supporting a standard payload of 30–34 tons and making it suitable for use on expressways, national highways, and complex road conditions.
2. Cost-Effective and Quick Return on Investment
Low Purchase Price: Approximately 30–40% cheaper than aluminum alloy tankers, significantly reducing the financial burden of the initial investment.
Universal Components: Axles, braking systems, tires, and other parts are interchangeable with those of standard cargo semi-trailers, ensuring access to a wide network of repair centers and keeping maintenance costs low.
3. Safety and Regulatory Compliance (Standard for Hazardous Chemicals Transport)
Standard features include ABS, emergency shut-off valves (bottom valves), European-standard manholes, vapor recovery systems, electrostatic grounding, flame arresters, and LED warning lights.
The tank body undergoes a rigorous triple-check process-including hydrostatic, airtightness, and leak tests-and all weld seams undergo 100% non-destructive testing to ensure maximum protection against leaks and explosions.
4. Disadvantages (Points to Note)
High Curb Weight: Heavier than aluminum alloy tankers by 3–5 tons, resulting in a slightly lower standard payload capacity and marginally higher fuel consumption.
Susceptibility to Corrosion: Carbon steel is vulnerable to acidic and alkaline substances; therefore, it requires periodic anti-corrosion painting (re-coating every 3–5 years) to prevent rust formation and potential leaks.
Shorter Service Life: Typically lasts 8–12 years under normal operating conditions (compared to 15–20 years for aluminum alloy tankers).
