High-Pressure 8-Pipe CNG Tube Trailer

| Product Overview

The 8 Pipes CNG Tube Trailer is a state-of-the-art mobile pressure vessel designed for the safe and efficient transportation of high-pressure gases such as compressed natural gas (CNG) and hydrogen. Manufactured by leading enterprises like Anhui Date Equipment Vehicle Co., Ltd. and CIMC Tonghua, this trailer features 8 seamless steel cylinders (tube bundles) fixed in parallel on a semi-trailer chassis, connected via tracheas and valves to form an integrated transport unit. With a high-pressure rating (up to 30MPa), it maximizes single-trip gas capacity, serving as a "mobile storage tank" for areas without pipeline coverage. Ideal for gas stations, industrial users, and hydrogen energy projects, it delivers reliable gas logistics support with strict adherence to international safety standards.

| Core Advantages

High-Efficiency Gas Transport

Utilizes high-pressure technology (20MPa/30MPa) to significantly increase gas volume per trip, reducing unit gas transportation costs. The 8-pipe modular design ensures optimal load distribution, enabling efficient point-to-point delivery. For hydrogen transport, a 30MPa trailer can carry 450-650kg per trip, outperforming traditional transport methods.

Multi-Layer Safety Protection

Seamless one-piece cylinders (Type CNG-1) eliminate weld-related risks, ensuring structural integrity.

Equipped with pressure sensors, safety valves, burst discs, and leak detection systems for comprehensive hazard prevention.

Undergoes rigorous testing: Hydrostatic testing, airtightness testing, and non-destructive testing to guarantee operational safety.

Static grounding clamps and anti-rolling devices prevent static buildup and vehicle movement during loading/unloading.

Strong Adaptability & Flexibility

The modular tube bundle design allows flexible adjustment of cylinder quantity and arrangement based on transport needs. It effectively compensates for pipeline limitations, serving remote factories, hydrogen refueling stations, and urban gas supply networks. Compatible with multiple high-pressure gases (CNG, hydrogen), it supports diverse industrial and energy applications.

| Application Fields

Hydrogen Energy Logistics

Acts as a critical link between hydrogen producers (chemical plants, electrolysis facilities) and end-users (hydrogen refueling stations). Enables efficient transport of hydrogen for fuel cell vehicles (buses, logistics trucks, passenger cars), supporting the development of clean energy ecosystems.

Petrochemical & Industrial Supply

Supplies high-purity hydrogen as feedstock for hydrogenation reactions in refineries (hydrocracking, hydrotreating) and chemical production (ammonia synthesis). Provides industrial gases to electronics (semiconductor manufacturing), metallurgy (heat treatment), float glass production, and aerospace sectors as protective atmospheres or reducing agents.

Urban Gas Station Support

Transports compressed natural gas (CNG) to urban refueling stations, supporting natural gas-powered vehicles. Ideal for regions without pipeline networks, ensuring stable gas supply for public transportation and private vehicles, reducing carbon emissions.

| Operation & Safety Guidelines

Pre-Operation Preparation

Guide the trailer to the designated position, place anti-rolling devices and support blocks, and secure the landing gear.

Connect static grounding clamps to both the vehicle body and cylinders to eliminate static buildup.

Inspect cylinder seals, hoses, and valves for damage or leaks; verify pressure gauge functionality.

Loading/Unloading Procedures

Connect the discharge hose firmly, confirm the connection is secure, and stand to the side when operating valves.

Open the main valve first, then sequence-open cylinder valves; adjust the dispenser inlet valve to control pressure (not exceeding 20MPa).

For unloading, close valves in reverse order and vent residual pressure from the hose before disconnection.

Critical Safety Rules

Never operate the trailer without proper static grounding or anti-rolling devices.

Avoid rapid valve opening/closing to prevent pressure surges.

Do not disconnect hoses until the system is fully depressurized.

Monitor pressure continuously during operation; stop immediately if abnormal readings occur.

| Production Process

The 8 Pipes CNG Tube Trailer is manufactured through a precision-driven process. High-strength seamless steel is selected for the cylinders, which undergo hot forging and precision machining to achieve uniform wall thickness. The tube bundles are assembled and fixed on the semi-trailer chassis with high-strength brackets, ensuring stability during transport. Safety components (pressure sensors, safety valves) are sourced from certified suppliers and calibrated to meet strict industry standards. The entire unit undergoes hydrostatic testing (to verify pressure resistance), airtightness testing (to detect leaks), and non-destructive testing (to check for internal defects). Each trailer is inspected by professional quality control teams and complies with national and international mobile pressure vessel regulations.

| FAQ

What is the maximum pressure the 8 Pipes CNG Tube Trailer can withstand?

The trailer is designed for high-pressure transport, with a typical working pressure of 20MPa or 30MPa, depending on configuration. It is engineered to meet strict pressure vessel standards to ensure safe operation under rated conditions.

Can it transport gases other than CNG and hydrogen?

The trailer is primarily designed for CNG and hydrogen transport. For other industrial gases, custom modifications may be required to meet specific gas compatibility and pressure requirements. Contact our technical team for personalized solutions.

How often does the trailer require maintenance?

Regular maintenance is required per industry regulations. Key checks include monthly inspections of valves, hoses, and safety devices; annual hydrostatic testing; and periodic non-destructive testing. Refer to the operation manual for a detailed maintenance schedule.
