A tube trailer is a type of mobile pressure vessel unit used for transporting high-pressure gases (e.g., Compressed Natural Gas - CNG, hydrogen). It consists of multiple large-capacity seamless steel cylinders (the tube bundle) fixed onto a trailer chassis.
What are the main application scenarios for tube trailers?
They are primarily used to transport CNG or hydrogen to urban refueling stations, supply industrial gases to remote factories without pipeline coverage, and serve as a feedstock source for hydrogenation reactions in the petrochemical industry.
What is the basic operation procedure for a tube trailer?
The basic procedure involves three steps: 1. Preparation: Position the vehicle, secure it with chocks, connect static grounding, and perform safety checks. 2. Unloading/Loading: Connect hoses, open/close valves in sequence, and control pressure. 3. Completion: Depressurize, disconnect hoses, remove grounding, and guide the vehicle away.
What are the most critical safety requirements during operation?
Critical requirements include: Preventing vehicle movement (using anti-roll devices and support blocks); Effective static grounding (connecting to both the vehicle body and cylinders separately); Proper valve operation (standing to the side and opening slowly); Strictly avoiding pressurized operations (ensuring hoses are depressurized before disconnection); and Pressure monitoring.
