Tube Trailer


A tube trailer is a type of semitrailer specifically designed to transport cryogenic gases. These trailers are equipped with long, high-pressure tubes or cylinders that contain gases in a compressed or liquefied state at extremely low temperatures.


The primary function of a tube trailer is to safely transport large volumes of cryogenic gases from production facilities to end-users or distribution points. These gases can include:

  • Oxygen (O₂)
  • Nitrogen (N₂)
  • Hydrogen (H₂)
  • Helium (He)
  • Argon (Ar)
  • Natural Gas (LNG)


  1. High-Pressure Tubes or Cylinders:
  • Made of high-strength materials like steel or composite materials to withstand the high pressures of the contained gases.
  1. Manifold System:
  • A series of valves and piping that allow for the filling and dispensing of gases from the tubes.
  1. Insulation:
  • Insulating materials are used to maintain the low temperatures required for cryogenic gases, preventing heat ingress and maintaining the liquid state of the gases.
  1. Pressure Relief Devices:
  • Safety devices that release gas if the pressure exceeds safe limits to prevent explosions.
  1. Temperature and Pressure Monitoring:
  • Instruments to monitor and control the temperature and pressure within the tubes, ensuring safe transportation conditions.
  1. Frame and Chassis:
  • A sturdy structure that supports the tubes and connects to a tractor unit for transportation.


  1. Industrial Gas Supply:
  • Supplying manufacturing plants, hospitals, laboratories, and other facilities with cryogenic gases for various industrial processes.
  1. Energy Sector:
  • Transporting liquefied natural gas (LNG) to remote areas or facilities that are not connected to natural gas pipelines.
  1. Medical Use:
  • Delivering medical-grade gases like oxygen to hospitals and healthcare facilities.
  1. Research and Development:
  • Providing specialized gases for scientific research and experimental purposes.


  • High Capacity:
  • Able to transport large volumes of gas in a single trip, reducing the number of trips required.
  • Efficiency:
  • Designed for quick loading and unloading, minimizing downtime.
  • Safety:
  • Equipped with multiple safety features to prevent accidents and ensure safe handling of cryogenic gases.

Safety Considerations

  • Regular Inspections:
  • Frequent checks and maintenance of tubes, valves, and safety devices to ensure integrity and performance.
  • Training:
  • Personnel involved in the transportation of cryogenic gases must be properly trained in handling and emergency procedures.
  • Regulations Compliance:
  • Adherence to local and international regulations regarding the transportation of hazardous materials.

Tube trailers are essential for the efficient and safe transportation of cryogenic gases across various industries. Their design, which includes high-pressure tubes, insulation, and safety systems, ensures that large volumes of gas can be transported while maintaining low temperatures and preventing leaks or accidents. Regular maintenance and compliance with safety regulations are critical to the operation of tube trailers.
