Liquid Nitrogen / Oxygen Cryogenic Tanker
The Liquid Nitrogen / Oxygen Cryogenic Tanker is an ultra-low temperature, high-precision pressure vessel transport trailer specifically engineered for the high-volume, long-distance road distribution of industrial liquefied gases, including liquid nitrogen ($LIN$, -196°C), liquid oxygen ($LOX$, -183°C), and liquid argon ($LAR$, -186°C). Built in strict compliance with international cryogenic transport codes (ASME Section VIII, ADR Class 2, EN 13530, and GB150), it utilizes a high-efficiency double-wall vacuum-insulated design. The inner vessel is fabricated from high-strength austenitic stainless steel (S30408 / AISI 304) capable of remaining ductile at extreme cryogenic temperatures, while the outer carbon steel or stainless steel shell maintains an evacuated annular space filled with multi-layer reflective foil and expanded perlite insulation. Outfitted with an oxygen-cleaned, grease-free stainless steel cryogenic valve cabinet, differential pressure liquid level gauges, dual redundant safety relief valves, and an onboard pressure-building vaporizer coil, it guarantees an ultra-low daily Boil-Off Rate (BOR) and safe transfer operations. Paired with 3 heavy-duty commercial axles, advanced air ride suspension, and WABCO ABS/EBS pneumatic braking with Roll Stability Support (RSS), it provides exceptional highway stability, vacuum longevity, and operational safety. Fully certified under ASME, ADR, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Oxygen-Cleaned Austenitic Inner Shell & High-Vacuum Insulation
- Austenitic Stainless Steel Inner Vessel: Constructed from high-purity S30408 (AISI 304) stainless steel, ensuring high toughness and impact resistance at extreme sub-zero temperatures down to -196°C.
- Strict Oxygen Cleaning & Degreasing: Undergoes thorough chemical degreasing, solvent washing, and blacklight inspection during assembly to eliminate organic residues, satisfying stringent safety requirements for Liquid Oxygen ($LOX$) transport.
- Helium-Tested High Vacuum: The annular jacket features multi-layer reflective super-insulation and perlite powder, evacuated and verified using precision helium mass spectrometer leak detectors to guarantee daily boil-off rates $\le 0.30\%$.
2. Cryogenic Valving & Autonomous Pressure Building
- Stainless Extended-Stem Valves: All pipework, manifolds, and shut-off valves inside the lockable cabinet are made of high-grade stainless steel with extended stems to protect packing seals from freezing.
- Integrated Pressure Building Coil: Outfitted with an under-slung pressure-building vaporizer coil, allowing operators to pressurize the vessel autonomously for rapid liquid discharge at customer sites without external pumps.
- Redundant Overpressure Protection: Dual safety relief valves connected via a three-way changeover valve allow online inspection and valve replacement without taking the trailer out of service.
3. Integrated Low-CG Sub-Frame & Roll Stability Controls
- Low Center of Gravity Saddle Design: The cylindrical pressure vessel is integrated into a heavy-duty Q345B/Q550 steel sub-frame using low-heat-leak support saddles, providing lower overall clearance and superior dynamic balance.
- WABCO EBS with Roll Stability Support (RSS): Features electronic braking and RSS to automatically apply brake pressure to inner wheels during high lateral acceleration to counteract rollover risks.
- Air Ride Suspension Smoothness: Pneumatic air suspension cushions sensitive piping, vacuum joints, and structural welds from high-frequency road shocks.
Commercial & Logistics Terms
- Warranty Policy: 3 to 5-Year warranty for the inner pressure vessel shell and vacuum insulation system; 1-Year warranty for axles, valves, and running gear.
- Delivery Lead Time: 40 – 45 working days upon order confirmation and technical drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
