The oil tank semi-trailer consists of a tank body, a frame, a running mechanism, safety accessories, etc. It is connected to the tractor through a towing pin and is suitable for long-distance highway transportation. Its core advantages include:
1.Large-capacity loading-a single transport volume can reach 30,000~50,000 liters, reducing transportation costs.
2. Safe and reliable-adopting explosion-proof and leak-proof design, in line with international transportation standards (such as DOT, ADR).
3. Multi-functional adaptation-can transport different media such as diesel, gasoline, methanol, edible oil, chemical liquids, etc.
4. Efficient unloading-optional self-priming pump, pneumatic unloading and other systems to improve loading and unloading efficiency.
Main structure and function
(1) Tank
Material: carbon steel, stainless steel (304/316L), aluminum alloy, etc., corrosion-resistant and high-pressure-resistant.
Structure: circular/elliptical cross-section, wave-breaking plates can be installed inside to reduce liquid sloshing.
Optional configuration:
Insulation layer (suitable for low-temperature liquid transportation).
Multi-compartment design (independent compartments, capable of transporting different oil products at the same time).
(2) Safety system
Overfill prevention valve.
Static discharge system (prevents static sparks).
Emergency shut-off valve (automatically closes in case of accidental leakage).
Breathing valve (balances the air pressure in the tank).
(3) Unloading method
Gravity unloading (gravity unloading, suitable for low-viscosity liquids).
Pumping unloading (optional centrifugal pump, gear pump, etc.).
Pneumatic unloading (compressed air driven, suitable for viscous liquids).
