Cryogenic liquid transport semi-trailer

Core positioning: Professional adaptation to low-temperature transportation needs in multiple scenarios

The Cryogenic liquid transport semi-trailer is designed specifically for Cryogenic liquid transport in extremely cold environments of -196 ℃, and can be widely adapted to transport various media such as liquid oxygen (LO ₂), liquid nitrogen (LN ₂), liquid argon (LAr), liquefied natural gas (LNG), liquefied carbon dioxide (LCO ₂), etc. Whether it is industrial gas distribution, LNG city gas supply peak shaving, hospital medical oxygen supply, or transportation of cryogenic media for food processing, flexible configuration and stable performance can meet the personalized transportation requirements of different industries, making it an indispensable core equipment in modern cryogenic logistics systems.

 Core structure: Building a solid foundation for safe transportation

The Cryogenic liquid transport semi-trailer adopts a scientific double-layer vacuum insulated tank structure, consisting of an inner tank, an outer tank, and a sandwich insulation system, to ensure the stability of low-temperature medium storage and transportation from the structural source:

-Inner tank: Made of high-quality low-temperature steel such as 30408 austenitic stainless steel, it has strong low-temperature impact resistance and corrosion resistance. It can directly hold cryogenic liquids at -196 ℃, ensuring the purity and pollution-free nature of the medium.

-Outer tank: Made of Q345R high-strength carbon steel, combined with anti-corrosion spraying technology, effectively enhances the structural strength of the vehicle, resists bumps and external environmental erosion during long-distance transportation, and extends the service life of the entire vehicle.

-Sandwich insulation system: using high vacuum multi-layer winding insulation technology, dozens of layers of aluminum foil are wrapped inside the sandwich and pumped to a high vacuum state. At the same time, a dedicated adsorbent is configured to maintain long-term vacuum degree, maximizing the blocking of external heat transfer and significantly reducing medium volatilization loss.

-Auxiliary system: Integrated with a complete set of auxiliary equipment such as an operation box, low-temperature liquid pump, automatic compressor, and flow hose. The operating valves and instruments are centrally arranged inside the operation box, with a compact structure and convenient operation. At the same time, an explosion-proof control box is equipped to enhance operational safety.

Core advantages: Safety, efficiency, and low loss in one

1. Ultimate security guarantee, worry free transportation throughout the entire process

Safety is the core requirement for low-temperature transportation. This product fully implements multiple safety protection designs and builds a full process safety barrier:

-The Cryogenic liquid transport semi-trailer is equipped with the WABCO EBS electronic braking system, which monitors the braking status in real time and automatically adjusts the braking force distribution in emergency situations to avoid medium shaking or leakage caused by unstable braking, adding an "intelligent safety valve" to driving safety.

-Low temperature liquid transport semi-trailer is equipped with dual safety release devices and emergency shut-off valves. When the tank pressure exceeds the set value, the safety valve automatically releases pressure; In case of emergencies, the emergency shut-off valve can be remotely closed through the control switches on both sides of the operation box, quickly blocking the transmission of the medium and reducing risks.

-The Cryogenic liquid transport semi-trailer is equipped with a gas concentration detection and alarm system and a portable detector. Once a medium leak occurs, an alarm is immediately triggered and displayed accurately on the control box screen, making it easy for operators to quickly handle the situation; All stainless steel pipelines and valves ensure no leakage hazards in extreme low temperature environments.

-The rear bumper of the cryogenic liquid transport semi-trailer adopts the slant support reinforcement technology, which greatly improves the impact strength, and can effectively protect the core area of the tank body in case of collision; The entire vehicle has passed multiple international and domestic authoritative certifications such as ISO 9001, GB, ASME, etc. Each weld seam has undergone flaw detection testing, and the pipeline interface has undergone repeated pressure testing, with quality traceable throughout the entire process.

2. Efficient insulation technology significantly reduces losses

The Cryogenic liquid transport semi-trailer relies on advanced high vacuum multi-layer winding insulation technology, and the vacuum degree of the tank body can reach the standard of a static storage tank. Without discharging liquid, the safety valve of the fully loaded tank body will not open due to pressure exceeding the standard caused by temperature rise for 15-30 days. The daily evaporation rate (BOG) of the medium is controlled within 0.2% -0.5%, with LNG transportation having a daily evaporation rate as low as 0.2% -0.3%, far better than the industry average, significantly reducing medium loss during transportation and improving operational efficiency. At the same time, it is equipped with precise intelligent level gauges, which have higher measurement accuracy compared to ordinary digital level gauges, making it easier for operators to grasp the remaining medium in real time and optimize transportation scheduling.

3. Strong load-bearing performance, suitable for diverse needs

The chassis of the Cryogenic liquid transport semi-trailer is equipped with high-quality core components such as German BMP axles. After more than ten years of market verification, it has strong rigidity and good wear resistance, and can adapt to the long-distance transportation needs of different road conditions. The number of vehicle axles covers various configurations such as 2-axle and 3-axle, with a wide range of transport volumes, from 5m ³ to 67m ³, which can be customized. Among them, the common volume for LNG transport is 20-52m ³, which meets different transport volume needs; The total weight of the full load can reach 31-45 tons, improving the efficiency of single transportation and reducing unit transportation costs under the premise of compliant loading. In addition, the Cryogenic liquid transport semi-trailer adopts an upper inlet system to optimize the liquid inflow path, reduce the vortex and impact inside the tank, avoid temperature fluctuations caused by severe shaking of the medium, and ensure smooth and controllable transmission process.

4. Intelligent and convenient management to improve operational efficiency

The Cryogenic liquid transport semi-trailer can be equipped with a GPS remote monitoring system to achieve 24-hour tracking of key data such as vehicle position, tank pressure, temperature, etc. The data is transmitted in real-time to the dispatch room, making it easy for management personnel to accurately dispatch and timely detect abnormal situations. The design of the cabin takes into account the convenience of loading and unloading. Some models are equipped with transition boards, which are the same width as the ground ox pulley and seamlessly connect to the loading and unloading platform, improving loading and unloading efficiency by more than 30%; Pre embedded drainage design with slotted roof to prevent condensation water accumulation and extend the life of the cabin.
