LNG cryogenic transport vehicle

LNG cryogenic transport vehicle

Core technology: ultra-low temperature insulation, ultimate cold endurance

The LNG cryogenic transport vehicle tank serves as the transportation core and adopts a double-layer vacuum insulation structure design. The inner tank is made of S30408 low-temperature stainless steel material, which has excellent resistance to low-temperature impact and corrosion, and can directly hold liquefied natural gas at -162 ℃; The outer tank is made of Q345R high-strength carbon steel, processed through precision forming and welding processes to ensure structural stability. The interlayer of the inner and outer tanks is filled with multi-layer aluminum foil composite insulation material and subjected to high vacuum extraction, with a vacuum degree of ≤ 5 × 10 ⁻⁴ Pa, which can maximize the suppression of thermal conductivity, convection, and radiation heat transfer, and control the daily evaporation loss (BOG) at an industry-leading level of 0.2% -0.3%, ensuring that the medium maintains liquid stability continuously during long-distance transportation.

For different transportation needs, LNG cryogenic transport vehicle offer multiple volume specifications to choose from. The main model has a tank capacity of 52.5m ³, a maximum allowable filling capacity of 24500Kg, and a medium unit filling capacity of 466.6Kg/m ³. A single transportation can meet the replenishment needs of large industrial users or multiple gas stations. Paired with an efficient supercharger and pressure regulation system, the pressure is increased by precisely controlling the vaporization of a small amount of liquid, and the unloading rate can reach 300GPM, greatly improving loading and unloading efficiency.

 Full dimensional security: intelligent prevention and control, multiple guarantees without blind spots

Relying on strict safety design standards, LNG cryogenic transport vehicle have built a full chain safety protection system, which not only complies with the "Low Temperature Insulated Pressure Vessels" (GB18442-2001) and the international ASME Section VIII standard, but also has passed multiple international authoritative certifications such as the EU E/e-mark certification, the Eurasian Economic Union EAC certification (TR EAEU 036/2016), and the US NFPA 59A/57 standard. At the same time, it meets the requirements of the ADR Dangerous Goods Road Transport Agreement and can enter mainstream overseas markets such as Europe, America, and Central Asia without barriers. LNG cryogenic transport vehicle have undergone more than 30 rigorous tests, including hydrostatic testing, airtightness testing, radiographic non-destructive testing, and low-temperature condition simulation testing, to ensure long-term reliability in different climates and road conditions.

-Intelligent monitoring and warning: LNG cryogenic transport vehicle are equipped with high-precision differential pressure level gauges (with a testing accuracy of 2.5 levels), YN-100 pressure gauges, and gas leakage alarm systems, which monitor the liquid level, pressure changes, and medium leakage status in the tank in real time. In case of abnormalities, sound and light alarms are immediately triggered to reserve sufficient emergency response time for drivers.

-Active safety control: The LNG cryogenic transport vehicle is equipped with DA22Y-40P low-temperature fully open safety valve and emergency shut-off device (DJQ series), with a set pressure of 0.65MPa for the safety valve. It automatically releases pressure when overpressure occurs and can complete pipeline closure within 5 seconds in emergency situations; Equipped with HTY1250 static conductive tape, it effectively releases static electricity generated during transportation and eliminates the risk of static electricity ignition.

-Driving safety guarantee: The LNG cryogenic transport vehicle adopts BPW air suspension and 10T axle, matched with dual vacuum tires and aluminum alloy steel rims, which have excellent shock absorption performance and lightweight advantages; Equipped with the Kemi EBS electronic brake system and hydraulic retarder as standard, it can significantly reduce brake wear on long downhill sections. The designed speed limit on flat roads is 80Km/h, and the turning speed limit is 20Km/h, ensuring stable driving in complex road conditions. The maximum roll stability angle under full load is ≥ 23 °, and the anti overturning ability is outstanding.

Performance upgrade: Efficient operation, significant cost reduction and efficiency improvement

The LNG cryogenic transport vehicle adopts a modular and internationally compatible design concept, with core components selected from globally recognized top brands in the industry to ensure convenient overseas maintenance. The 50 # JOST traction pin ensures reliable traction connection, and the JOST legs are easy to operate and have stable load-bearing capacity; The valve system can flexibly select products from Shanghai Baitu/Chengdu Chuankong or well-known European and American brands according to the target market demand. The gas phase and liquid phase pipelines are respectively equipped with DN40 and DN50 flange interfaces, compatible with mainstream loading and unloading equipment worldwide, and the loading and unloading connections are convenient and sealed; The application of aluminum alloy toolboxes, side protection, and tire guards enables lightweight design of the entire vehicle, with a curb weight controlled at 15500Kg. The configuration can be flexibly adjusted according to the load regulations of different countries, maximizing the effective load within the compliance range and reducing unit transportation costs.

In terms of power matching, liquefied natural gas low-temperature transport vehicles can be adapted to high horsepower natural gas engines such as Cummins A15N and Weichai WP13NG, with a maximum power of 580 horsepower and peak torque exceeding 2600 N · m. Paired with ZF/Eaton AMT automatic transmissions, the shift response is as fast as 0.62 seconds, and the transmission efficiency is as high as 99.7%. While the power performance is comparable to diesel vehicles, the gas consumption is reduced by 3% -8% compared to diesel vehicles. Combined with LNG's price advantage of 20% -30% compared to diesel, the annual operating cost can be reduced by more than 100000 yuan. The expected service life of the entire vehicle design is 10 years, and the core components enjoy comprehensive after-sales support, significantly reducing the full life cycle operation and maintenance costs.
