LPG and LNG Tank Trailers for Gas Distribution

Gas transport splits into two completely different engineering problems. LPG is a certified pressure vessel carrying liquid at ambient temperature. LNG and liquid nitrogen are cryogenic cargoes needing vacuum multi-layer insulation and materials that stay tough at -196 degrees. Specifying the wrong one is a safety failure, not a configuration error.

Pain Points

What Goes Wrong In This Sector

  • General steel is not certified for LPG pressure service and cannot be used
  • Foam-insulated tanks cannot hold cryogenic temperature over a long haul
  • Vacuum insulation is heavy and leaves too little payload on a steel chassis
  • Cryogenic tank level cannot be checked visually without a calibrated gauge
  • Exposed cryogenic valves are damaged and unsafe to operate after road use
Requirements

What The Job Actually Needs

  • Q370R pressure vessel plate for LPG, S30408 and 30408 stainless for cryogenic service
  • Metal double-cylinder vacuum fibre insulation on every cryogenic build
  • Aluminium alloy tanks and main beams to recover payload on cryogenic work
  • Rear operation boxes protecting valves and instruments
  • Calibrated level gauges, specified relief valve settings and optional vapour recovery

Scenarios

Typical Applications

  • LPG distribution from import terminals to bottling plants
  • LNG supply to satellite and vehicle fuelling stations
  • Liquid nitrogen delivery to industrial and food processing plants
  • Autogas supply to filling station networks
  • Cryogenic gas supply to remote mining and drilling sites
Specification Advice

What To Get Right At Order

  • State the exact medium, working pressure and design temperature at enquiry
  • Expect 20 to 24 tonnes payload on a cryogenic build at a 40 tonne gross
  • Specify vapour recovery where boil-off must be captured rather than vented
  • Confirm the pressure vessel certification your destination requires before order
  • Plan the cold-down procedure and operator training before the first fill

Solutions

How We Support The Purchase

Custom Trailer Engineering

A standard build is a compromise averaged across every market. Your axle limits, road surface, climate, cargo density and local parts supply are not average, and the gap between the average and your reality is where trailers break.

Choosing the Right Configuration

Buyers are usually given a model number and a price. What determines whether the trailer earns is the configuration behind that number, and it is easy to get wrong from a catalogue photograph.

Export Shipping and Documentation

Trailer shipping is not container shipping. Many models cannot go in a box at all, freight rates move while vehicle prices stay fixed, and import clearance depends on documentation that varies country by country.

After Sales and Spare Parts

The common failure is not a defective trailer, it is a trailer nobody can get parts for. Once a supplier changes model or loses interest, an otherwise sound vehicle becomes scrap over a single unavailable component.

FAQ

Industrial Gas and LNG Questions

Can One Trailer Carry Both LPG and LNG

No. LPG is a pressure vessel at ambient temperature; LNG needs vacuum cryogenic insulation. They are different vessels and cannot be interchanged.

Why Is Cryogenic Payload So Low

A vacuum-insulated double-cylinder vessel is inherently heavy. Typical payload is 20 to 24 tonnes on a 40 tonne gross. Aluminium alloy tanks and aluminium main beams recover some of it.

What Pressure Vessel Plate Do You Use for LPG

Q370R at 11mm on the bullet tank builds, with matching Q370R end plates. Aluminium alloy 5083 is available where tare weight matters more.

How Do I Monitor a Cryogenic Tank Level

With a calibrated gauge. Our LNG build uses an MZC-IIA reading 0 to 1500mm mounted in the cabinet, since the level cannot be checked visually.

Do You Supply Liquid Nitrogen Tankers

Yes, 31000 litres at 0.8MPa working pressure in S30408 with vacuum multi-layer insulation. Nitrogen is much denser than LNG, so the volume for a given weight limit is lower.
