Efficient 12-Pipe CNG Transport Tube Trailer

| Product Overview

12 Pipes CNG Tube Trailer is a specialized mobile pressure vessel engineered for safe and efficient transportation of high-pressure gases such as compressed natural gas (CNG) and hydrogen. Composed of 12 large-capacity seamless steel cylinders fixed in parallel on a semi-trailer chassis, all cylinders are interconnected via tracheas and valves to form an integrated transport unit. With a nominal working pressure of 20MPa and service temperature range of -40℃ to 60℃, this tube trailer series (including models ZLN9370GGY, ZLN9390GGY, etc.) offers diverse total volumes from 18m³ to 25.38m³, catering to different gas transport demands. It serves as a vital "mobile gas storage tank" for gas stations, industrial users, and hydrogen refueling stations that lack pipeline coverage.

| Core Advantages

High Transportation Efficiency

The trailer adopts high-pressure storage technology (20MPa) to maximize single-trip gas volume, effectively reducing the unit cost of gas transportation. Its modular tube bundle design allows flexible adjustment of cylinder quantity based on actual needs, further enhancing transport efficiency for different scenarios.

Reliable Safety Design

Equipped with seamless one-piece cylinders (Type CNG-1), it eliminates potential risks from welding seams. The cylinders are reinforced with high-strength metal liners and carbon fiber composite materials. Multiple safety devices including pressure sensors, safety valves, burst discs, and leak detection systems are installed. Rigorous tests like hydrostatic testing, airtightness testing, and non-destructive testing are conducted during manufacturing to ensure product reliability.

Strong Flexibility & Adaptability

As a mobile gas supply solution, it perfectly compensates for pipeline limitations. It can deliver gases directly to remote areas, hydrogen refueling stations, and industrial factories, achieving point-to-point efficient gas supply without being restricted by fixed pipeline networks.

| Application Fields

Hydrogen Energy Storage & Transport

It acts as a critical logistics link between hydrogen producers and end-users like hydrogen refueling stations. A 30MPa tube trailer can transport 450–650kg of hydrogen per trip, significantly cutting down the logistics cost of hydrogen energy.

It provides feedstock gas for hydrogenation reactions, widely applied in refinery processes such as hydrocracking and hydrotreating, as well as in ammonia production and other chemical manufacturing.

Industrial Gas Supply

It supplies high-purity hydrogen to sectors including electronics (semiconductor manufacturing), metallurgy (heat treatment), float glass production, and aerospace, serving as protective atmosphere, reducing agent, or raw material.

It transports CNG and hydrogen to urban refueling stations, supporting the operation of hydrogen fuel cell vehicles and natural gas vehicles, and promoting urban clean energy development.

| Operation & Safety Guidelines

Pre-operation Preparation

Guide the trailer to the designated position, place anti-rolling devices and support blocks, and lower the landing gear securely. Connect static grounding clamps to both the vehicle body and cylinders separately to eliminate static risks. Check cylinder seals and hose pressure to ensure no leakage.

Loading & Unloading Operation

Connect the discharge hose firmly, then open the main valve and cylinder valves in sequence. Open the dispenser inlet valve and monitor the pressure to ensure it does not exceed 20MPa. After unloading, close the valves in reverse order and vent residual pressure from the hose before disconnection.

Post-operation Procedures

Disconnect the hose, remove the static grounding clamps, and close the trailer rear door. Raise the landing gear and retrieve support blocks, then guide the vehicle to leave the area safely.

Key Safety Requirements

Prevent vehicle movement during operation with anti-rolling devices. Operate valves slowly and stand to the side to avoid potential hazards. Strictly prohibit any operation when the hose is under pressure.

| Production Process

Cylinder Manufacturing: Produce seamless steel cylinders using high-quality 4130X alloy steel, through processes of hot extrusion, cold drawing, and heat treatment to ensure high strength and pressure resistance.

Chassis Assembly: Weld and assemble the semi-trailer chassis, then conduct anti-corrosion treatment to extend service life.

Tube Bundle Integration: Fix the cylinders on the chassis in parallel, connect tracheas and valves, and install safety devices such as pressure sensors and safety valves.

Quality Testing: Carry out hydrostatic testing, airtightness testing, and non-destructive testing on the finished product to ensure compliance with safety standards.

Final Inspection & Delivery: Conduct overall performance inspection, then issue certification documents and deliver the qualified products to customers.

| FAQ

What is a CNG tube trailer?
