Liquid Nitrogen Tanker 31000L Semi-trailer China Factory for Sale
31000 litre liquid nitrogen tanker, S30408 pressure vessel at 0.8MPa working pressure.
Overview
What This Trailer Is Built For
A 31000 litre cryogenic tanker for liquid nitrogen at 10610 x 2500 x 3820mm, tare 16254kg and payload 23764kg within a 40000kg gross, all plus or minus 5 percent. The trailer height is adjusted to suit the tractor specification, and the traction pin sits 1320mm from the ground. Pressure-bearing components are S30408 stainless with a design pressure of 0.91MPa, a working pressure of 0.8MPa, a relief valve opening at 0.8MPa, and zero corrosion allowance. Insulation is vacuum multi-layer. Unit volume filling weight is 0.766kg per litre, which reflects the density of liquid nitrogen against lighter cryogenic products. Axles are 13 tonne FUWA.
Key Benefits
What You Get
- 31000 litres of liquid nitrogen at 0.766kg per litre is a full commercial industrial gas load
- S30408 stainless pressure-bearing components with zero corrosion allowance
- Vacuum multi-layer insulation holds cryogenic temperature over long hauls
- Trailer height adjusted to your tractor specification rather than a fixed figure
- 1320mm traction pin height matches standard industrial gas tractor fifth wheels
Problems Solved
What It Fixes
- Liquid nitrogen is denser than LNG and overloads tanks sized for lighter cryogens
- General steel is unsuitable for cryogenic pressure service
- Foam insulation cannot hold cryogenic temperature over distance
- A fixed trailer height does not match every tractor fifth wheel

Comparison
How It Compares
| Compared With | How This Model Differs |
|---|---|
| LNG cryogenic tanker | Liquid nitrogen is much denser at 0.766kg per litre against roughly 0.38 for LNG, so the same weight limit allows far less volume. |
| LPG pressure tanker | Nitrogen is carried cryogenically with vacuum insulation; LPG is a pressure vessel at ambient temperature. |
| Vacuum-insulated ISO tank | A dedicated semi-trailer carries more per trip; an ISO tank suits intermodal transfer. |
Use Guide
Operating This Trailer
- Complete the cold-down procedure before first filling
- Never adjust or bypass the 0.8MPa relief valve setting
- Log tank pressure and vacuum readings on the stated schedule
- Use cryogenic protective equipment at every transfer point
- Confirm the fifth wheel height matches the 1320mm traction pin height
