1. What is a tank semi-trailer?
A tank semi-trailer, also known as a tank trailer or liquid transporter, is a specialized vehicle designed for transporting liquids, gases, or powdered materials. Its main body is a sealed tank, typically made of carbon steel, stainless steel, or aluminum alloy, designed to safely carry and transport a variety of media.

2. What media do tank semi-trailers primarily transport?
A tank semi-trailer can transport a variety of media, depending on the tank material and design. Common transported media include:
Liquid fuels: gasoline, diesel, kerosene, etc.
Chemical liquids: corrosive liquids such as sulfuric acid, hydrochloric acid, and liquid caustic soda.
Edible liquids: milk, cooking oil, etc.
Liquid gases: liquefied petroleum gas (LPG), liquefied natural gas (LNG), etc.
Bulk powders: cement, fly ash, flour, etc.

3. What materials are available for tank semi-trailers, and how do I choose one?

Common tank materials include:
Carbon steel: Low cost, suitable for transporting non-corrosive liquids such as gasoline and diesel.
Stainless steel: Highly corrosion-resistant, suitable for transporting chemicals, edible liquids, and other media with high hygiene requirements.
Aluminum alloy: Lightweight, it effectively reduces vehicle weight and increases payload. It also offers excellent corrosion resistance and is a future trend.
When choosing a tank material, consider the nature of the transported medium (corrosive, flammable, explosive, or hygiene-related) and your budget.

4. What safety features are included in a tank trailer?
Due to the unique characteristics of the transported medium, the safety features of a tank trailer are crucial. Key safety features include:
Surfboard: A surfboard is installed inside the tank to reduce sloshing during operation and improve vehicle stability.
Safety valve and breather valve: Automatically open when the pressure inside the tank is too high or too low, maintaining pressure balance inside and outside the tank and preventing deformation. Static Grounding Device: Used to dissipate static electricity during loading and unloading operations, preventing sparks, especially when transporting flammable or explosive liquids.
Overflow Probe: Monitors the liquid level during loading to prevent spills.
Emergency Shut-Off Valve: In an emergency, quickly disconnects the tank from the outside to prevent leakage.

5. What Information Do I Need to Provide When Purchasing or Customizing a Tank Trailer?
To ensure that your customized tank trailer fully meets your needs and safety standards, you will need to provide the following key information:
Transported Medium: Specify the specific liquid, gas, or powder being transported.
Volume Requirement: Determine the tank’s capacity in cubic meters.
Axle Count and Load Capacity: Determine the number of axles required and the total load capacity in tons.
Tank Material Requirements: Choose between carbon steel, stainless steel, or aluminum alloy, depending on the properties of the medium.
Other Special Requirements: For example, whether insulation, heating, pumping systems, or compartments are required.
