LNG Cryogenic Liquid Transport Semi-Trailer (52.5 Cubic Meters)

LNG Cryogenic Liquid Transport Semi-Trailer (52.5 Cubic Meters)

Engineered exclusively for the safe and efficient bulk transportation of Liquefied Natural Gas (LNG), the 52.5 cubic meter cryogenic semi-trailer integrates cutting-edge insulation technology, heavy-duty structural engineering, and industry-leading safety systems. Designed to meet the large-volume logistics demands of the energy sector, this semi-trailer ensures stable, compliant, and cost-effective delivery of LNG across long distances and diverse road conditions, making it an indispensable asset for gas supply chains, power generation, industrial heating, and heavy-duty vehicle fueling applications.

Core Performance & Design Advantages

1. Large-Capacity Optimization & Exceptional Insulation

With a nominal volume of 52.5 cubic meters, the trailer features a precision-engineered tank structure that maximizes cargo capacity while maintaining optimal weight distribution and road maneuverability. The tank adopts a double-layer vacuum insulation design—an industry benchmark for LNG transportation: the inner tank is fabricated from high-grade 304/316L stainless steel, selected for its superior low-temperature toughness (-162℃ operating temperature), corrosion resistance, and compatibility with LNG. The outer tank is constructed from high-strength carbon steel, reinforced with anti-deformation ribs and a weather-resistant coating to ensure structural integrity under heavy loads and harsh environmental conditions. The vacuum interlayer is filled with high-efficiency insulation materials and equipped with a multi-layer aluminum foil radiation shield, achieving an ultra-low daily evaporation rate (≤0.15% of total volume). This minimizes LNG loss, extends storage time, and guarantees reliable transportation even for long-haul missions.

2. Heavy-Duty Structure & Comprehensive Safety Systems

The semi-trailer chassis is built with high-strength alloy steel beams, optimized through finite element analysis to enhance load-bearing capacity, fatigue resistance, and durability—capable of withstanding the rigors of industrial logistics and complex road networks. A full suite of safety features adheres to global LNG transportation standards (ISO, GB, DOT, ADR):

ISO-certified pressure relief valves with dual-stage protection, automatically regulating internal pressure to prevent tank overpressure and ensure operational safety;

Dual emergency cut-off valves (installed at the front and rear of the tank) with remote control functionality, enabling rapid shutdown of LNG flow in emergency scenarios to minimize leakage risks;

Real-time monitoring systems, including temperature (-162℃ ± 2℃), pressure, and methane leak detection sensors, which transmit data to the driver’s cab via a digital display for immediate visibility and alarm notifications;

Reinforced anti-roll bars, energy-absorbing rear bumpers, and high-visibility reflective warning signs (compliant with dangerous goods transportation regulations) to reduce collision risks;

Anti-lock braking systems (ABS), electronic stability control (ESC), and load-sensing axles to maintain vehicle stability during braking, cornering, and uneven road conditions—even with full LNG loads.

3. Reliable Operation & Low Maintenance Costs

Equipped with a high-performance cryogenic refrigeration unit (customized for LNG’s unique thermodynamic properties), the trailer maintains a stable internal temperature of -162℃ across extreme ambient conditions (-40℃ to +50℃), ensuring the integrity of LNG and preventing vaporization. The loading/unloading system features quick-connect, leak-proof dry-break couplings and a precision pressure-regulating valve, enabling efficient, spill-free transfer operations that save time and reduce waste. All key components—including valves, pumps, sensors, and seals—are sourced from globally recognized manufacturers specializing in cryogenic equipment, ensuring long service life and easy availability of spare parts. Additional design highlights include a centralized lubrication system, corrosion-resistant surface treatments, and accessible maintenance points (with detailed service manuals), reducing downtime and lowering long-term operational costs.

4. Compliance with Global Standards & Customization

This 52.5 cubic meter LNG semi-trailer fully complies with international safety and quality standards for cryogenic and dangerous goods transportation, including ISO 21009, GB/T 19905, DOT 400, and ADR R110. The tank body undergoes rigorous non-destructive testing (NDT), hydrostatic pressure testing, and vacuum tightness testing to guarantee structural integrity and leak resistance. To meet diverse customer needs and regional regulations, customization options are available:

Tank material upgrades (e.g., duplex stainless steel for enhanced corrosion resistance in harsh environments);

Additional safety features (e.g., flame arresters, emergency shutdown systems, and secondary containment);

Tailored chassis configurations (e.g., 3-axle or 4-axle designs, air suspension systems) to adapt to local road load limits;

Integrated telematics systems for real-time fleet monitoring, including location tracking, temperature/pressure data logging, and maintenance reminders.

Application Scenarios
