LNG Cryogenic Liquid Tank Semi-Trailer
The LNG Cryogenic Liquid Tank Semi-Trailer is an advanced, high-precision cryogenic pressure vessel transport trailer engineered specifically for the safe, ultra-low temperature (-162°C) road distribution and bulk hauling of Liquefied Natural Gas (LNG). Built in strict compliance with international cryogenic standards (such as ASME Section VIII, ADR Class 2, EN 13530, and GB150), the tanker features a sophisticated double-wall vacuum-insulated design. The inner vessel is fabricated from high-strength austenitic stainless steel (S30408 / AISI 304) capable of withstanding cryogenic temperatures, while the outer carbon steel or stainless steel shell protects the annular space, which is filled with high-performance vacuum powder insulation (perlite) and multi-layer reflective foil. Equipped with a specialized cryogenic valve cabinet, pressure building regulators, dual safety relief valves, differential pressure liquid level gauges, and emergency shut-off systems, it ensures minimal boil-off rate (BOR) and maximum thermal retention. Paired with 3 commercial axles, advanced air ride suspension, and dual-line WABCO ABS/EBS pneumatic braking with Roll Stability Support (RSS), it delivers exceptional highway stability, vacuum longevity, and cryogenic safety. Fully certified under ASME, ADR, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Double-Wall Vacuum Insulation & Cryogenic Integrity
- Low-Temperature Stainless Inner Shell: Fabricated from premium austenitic stainless steel (S30408) specifically certified for cryogenic service down to -196°C, maintaining high impact toughness and structural strength without brittle fracture risks.
- Advanced Vacuum Powder Insulation: The annular space between the inner vessel and outer shell is evacuated to a high-vacuum state and filled with specialized thermal insulation powder combined with multilayer reflective foil, restricting heat ingress and limiting daily boil-off rates (BOR) to under 0.35%.
- Rigid Inner Vessel Supports: Engineered with low-heat-leak stainless steel support legs and anti-vibration bracing to absorb dynamic longitudinal and lateral road forces while isolating thermal bridges.
2. Specialized Cryogenic Valving & Pressure Control
- Cryogenic Control Cabinet: All filling, discharge, vapor return, and pressure building valves are housed in a secure rear or side stainless steel cabinet, utilizing extended-stem cryogenic globe valves designed to prevent stem freezing and leakage.
- Integrated Pressure Building System: Features an onboard pressure building vaporizing coil that allows operators to raise inner tank pressure autonomously to facilitate rapid liquid transfer without external pumps.
- Dual-Set Safety Relief Architecture: Equipped with parallel safety relief valves and rupture discs connected via a three-way changeover valve, ensuring continuous overpressure protection during transport.
3. Low CG Chassis Integration & Advanced Braking Safety
- Optimized Center of Gravity (CG): The cylindrical tank is secured to a robust structural sub-frame designed to maintain a low profile, ensuring maximum highway stability and minimizing rollover risks during transit.
- WABCO EBS with Roll Stability Support (RSS): Integrated electronic braking system with RSS automatically engages selective wheel braking if lateral acceleration limits are exceeded on sharp curves.
- Air Ride Suspension Smoothness: Outfitted with adjustable air suspension to cushion sensitive cryogenic vessels and pipe joints from harsh road shock and high-frequency vibration.
Commercial & Logistics Terms
- Warranty Policy: 3 to 5-Year warranty for the inner pressure vessel and vacuum insulation performance; 1-Year warranty for axles, tires, and cryogenic valves.
- Delivery Lead Time: 45 – 50 working days upon order confirmation and cryogenic engineering drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
