CDW-24000AT Fluorescent Magnetic Particle Testing Machine for Gas Cylinders

CDW-24000AT Fluorescent Magnetic Particle Inspection Machine is a specialized NDT system designed for the inspection of surface and near-surface defects in gas cylinders.

  • Application: Suitable for magnetic particle inspection of various types of gas cylinders, including seamless steel cylinders, composite cylinders, and fire extinguishers.

  • High Efficiency: Automated magnetization, spraying, observation, and demagnetization processes.

  • Magnetization Modes: Supports both circular magnetization (for longitudinal cracks) and longitudinal magnetization (for transverse cracks).

  • Lighting System: Integrated high-intensity UV LED lighting with optional white light for inspection and cleaning.

  • Loading System: Roller-type or automatic loading options available.

  • Control System: PLC-based control system with touchscreen HMI for easy operation and parameter setting.

The CDW-24000AT Fluorescent Magnetic Particle Inspection Machine is a high-performance and fully automated NDT system specifically engineered for the non-destructive testing of gas cylinders. This advanced equipment applies fluorescent magnetic particle inspection (FMPI) to accurately detect surface and near-surface defects, such as cracks, laps, seams, and inclusions.

Designed for industrial users with high standards in flaw detection, the CDW-24000AT combines high sensitivity, efficiency, and safety in a compact and robust structure, making it an ideal choice for manufacturers and inspectors in the gas cylinder, fire extinguisher, and pressure vessel industries.


 Key Features and Advantages

  • Full Automation
    Integrated design with automated processes including loading, magnetization, fluorescent suspension spraying, UV inspection, demagnetization, and unloading, significantly improving detection speed and consistency.

  • Dual Magnetization Modes
    Supports both circular and longitudinal magnetization, enabling comprehensive detection of longitudinal and transverse cracks in cylinder bodies and shoulder areas.

  • High Sensitivity Fluorescent Detection
    Equipped with a powerful UV LED system (≥4500 μW/cm²) that meets international standards for fluorescent magnetic particle testing, ensuring superior visibility of flaw indications.

  • Versatile Cylinder Compatibility
    Accommodates a wide range of cylinder sizes (diameter: 100–400 mm; length: 300–1600 mm), suitable for seamless steel cylinders, composite cylinders, and fire extinguishing bottles.

  • Reliable Demagnetization System
    Built-in low-residual field demagnetizer ensures residual magnetism remains below 0.3 mT, meeting industry requirements and safety standards.

  • User-Friendly Interface
    The system adopts a PLC control system with a touchscreen HMI for intuitive operation, customizable parameters, and real-time process monitoring.

  • Durable and Easy to Maintain
    Constructed with industrial-grade materials and protective coatings for long-term, stable operation even in harsh workshop environments.

The CDW-24000AT Fluorescent Magnetic Particle Inspection Machine is a specialized solution for detecting surface and near-surface defects in cylindrical ferromagnetic components, especially gas cylinders. Its advanced performance and high adaptability make it suitable for a wide range of industries that require safe, reliable, and efficient non-destructive testing (NDT).


🔹 1. Gas Cylinder Manufacturing Industry

This is the primary application field of the CDW-24000AT. The machine is widely used for:

  • Seamless steel gas cylinders

  • Welded gas cylinders

  • Composite gas cylinders

  • Industrial and medical oxygen tanks

In gas cylinder production, fluorescent magnetic particle inspection ensures there are no cracks, laps, or other defects in the body or shoulder area of the cylinder, which is critical for pressure resistance and safety compliance.

Key benefit: Ensures structural integrity before delivery or filling.


🔹 2. Firefighting Equipment Manufacturers

Manufacturers of:

  • Fire extinguishers

  • CO₂ and dry powder cylinders

  • SCBA (self-contained breathing apparatus) tanks

must conduct strict NDT testing. The CDW-24000AT provides high sensitivity and full coverage of the curved cylinder surface, ensuring safety for emergency applications.

Key benefit: Prevents hidden defects that could lead to failure under pressure during emergencies.


🔹 3. Pressure Vessel Re-certification & Cylinder Testing Centers

In many countries, gas cylinders must undergo periodic inspection and re-certification. The CDW-24000AT is ideal for third-party inspection agencies, testing centers, and government-certified NDT labs, offering fast throughput and reliable results.

Key benefit: Speeds up high-volume inspection while maintaining strict compliance.


🔹 4. Oil & Gas and Petrochemical Industry

On-site storage and transport of gases like propane, acetylene, and hydrogen often require cylinder integrity assurance. The CDW-24000AT supports in-house quality checks for:

  • Refinery gas cylinders

  • Process gas bottles

  • Mobile pressure containers

Key benefit: Reduces downtime and ensures safety in explosive or corrosive environments.


🔹 5. Aerospace and Defense

In the aerospace and defense industries, portable gas cylinders are used in:

  • Aircraft oxygen supply systems

  • Escape slide inflation systems

  • Military breathing apparatus and ground support units

These critical systems demand flawless cylinders, and magnetic particle testing is an essential step in their validation process.

Key benefit: Enhances flight safety and defense equipment reliability.


🔹 6. Industrial Gas Distribution

Gas suppliers dealing in:

  • Argon, nitrogen, CO₂, and helium

  • Medical-grade gases

  • Specialty gas cylinders

can use this machine for incoming or outgoing cylinder quality inspection, helping maintain their reputation for safety and reliability.

Key benefit: Prevents field failures and strengthens customer trust.


🏷️ Summary

The CDW-24000AT is not limited to a single industry — it plays a vital role wherever gas cylinders and high-pressure vessels are manufactured, certified, or used. Its versatility, precision, and automation make it a valuable asset across industries focused on pressure equipment safety and non-destructive evaluation.
