Adopting 20 MPa high-pressure storage technology, the trailer maximizes gas loading volume per trip. This directly reduces the unit transportation cost of gases. The seamless cylinder design eliminates weld-related risks, further optimizing the overall operational efficiency.
Cylinders are reinforced with high-strength metal liners and carbon fiber composites. They are equipped with multiple safety devices such as pressure sensors, safety valves, burst discs, and leak detection systems. Rigorous testing procedures, including hydrostatic testing, airtightness testing, and non-destructive testing, are carried out during production to ensure product reliability.
The modular tube bundle structure allows flexible adjustment of cylinder quantity and layout based on actual transport demands. As a "mobile gas storage tank", it effectively compensates for pipeline limitations, providing stable gas supply to remote areas and temporary projects.
| Application Fields
Hydrogen Energy Storage & Transport
It serves as a critical logistics link between hydrogen production facilities and hydrogen refueling stations. 30 MPa high-pressure models can transport 450–650 kg of hydrogen per trip, significantly cutting the logistics cost of hydrogen energy.
Petrochemical Industry
It supplies hydrogen as a feedstock for hydrogenation reactions, widely used in hydrocracking and hydrotreating processes in refineries, as well as in ammonia production.
Industrial Gas Supply
It provides high-purity hydrogen and other industrial gases to sectors like electronics manufacturing, metallurgical heat treatment, float glass production, and aerospace.
Urban Energy Supply
It delivers CNG and hydrogen to urban refueling stations, supporting the operation of natural gas vehicles and hydrogen fuel cell vehicles.
| Operation & Safety Guidelines
Preparation Stage
Park the trailer at the designated position, place anti-rolling devices and support blocks, lower and secure the landing gear. Connect static grounding clamps to both the trailer body and cylinders, then check cylinder seals and hose pressure status.
Gas Loading & Unloading Stage
Connect the discharge hose and confirm it is securely fastened. Open the main valve first, then open the cylinder valves in sequence. Control the pressure within the 20 MPa limit during operation. When unloading is completed, close the valves in reverse order and vent the residual pressure in the hoses.
Post-operation Stage
Disconnect the hoses, remove the static grounding clamps, close the trailer rear door, raise the landing gear, and guide the vehicle to leave the area safely.
| Production Process
Cylinder Manufacturing
High-quality 4130× steel is used to produce seamless cylinders through hot extrusion and precision machining processes, ensuring the cylinders meet the CNG-1 type standard.
Chassis & Assembly
The semi-trailer chassis is welded and reinforced, then the processed cylinders are fixed in parallel on the chassis. Professional pipelines and valves are installed to connect all cylinders into a unified system.
Testing & Certification
The assembled trailer undergoes strict hydrostatic testing, airtightness testing, and non-destructive testing. Only products that pass all tests receive the qualification certificate and are put into storage.
