The application of VSNDT P series industrial endoscope in the hydrogen cylinder inspection project of a well-known environmental protection company in Henan Province reflects the important value of industrial endoscope technology in the field of new energy safety inspection. The following are the core points and technical analysis of the case:
Industry Demand
As a clean energy source, the safety of hydrogen storage and transportation containers (hydrogen cylinders) is directly related to the stability of the energy industry chain. An environmental protection company in Henan Province needs to conduct internal defect inspections on batches of hydrogen cylinders to ensure that there are no cracks, corrosion or foreign matter residues, and to avoid leakage risks caused by container aging or manufacturing defects.
Limitations of traditional testing
Traditional methods (such as water pressure testing and ultrasonic testing) cannot directly observe the internal structure of the container and may cause secondary damage to the hydrogen cylinder. Non-destructive testing (NDT) using industrial endoscopes has become the preferred solution.
Ultra-fine probe and high-definition imaging
Probe diameter: The P series is equipped with an ultra-thin probe with a diameter of ≤4mm, which can penetrate into the narrow opening of the hydrogen cylinder and is suitable for containers of different specifications.
Resolution: Supports 1080P high-definition image quality, clearly capturing tiny cracks on the inner wall (minimum detection accuracy reaches 0.02mm), meeting the high safety standards of hydrogen cylinders.
Flexible control and environmentally resistant design
Four-way bending: The probe can achieve 360° all-round turning and accurately locate blind spots (such as bottle mouth welding and inner wall grooves).
Protection level: IP67 waterproof and dustproof design, adapting to the condensation water or dust environment that may exist inside the hydrogen cylinder.
Intelligent analysis and data management
Real-time imaging: Built-in WIFI transmission module, the detection image can be synchronized to the computer or mobile terminal, supporting multi-person remote collaboration.
Defect marking: The software automatically marks cracks and corrosion points, generates inspection reports, and improves data traceability efficiency.
Procedure
Pretreatment: Clean the surface of the hydrogen cylinder to ensure smooth insertion of the probe.
Penetration inspection: Use the P series probe to scan the inner wall section by section, focusing on the welds and threaded connections.
Data analysis: Use software to magnify and measure the distance of suspicious areas to confirm the defect type and size.
Project Outcomes
Improved efficiency: The testing time for a single bottle is shortened to 15 minutes, which is 60% faster than the traditional method.
Defect detection rate: 3 micro cracks and 1 inner wall corrosion point were successfully found, avoiding potential leakage risks.
Cost savings: Reduce the number of disassembly and inspection times, lower the scrap rate of hydrogen cylinders, and save more than 200,000 yuan for a single project.
Technical adaptability
The high-pressure-resistant and explosion-proof design (optional) of the P series industrial endoscope can be extended to other high-pressure container inspection scenarios, such as CNG gas cylinders, liquid nitrogen storage tanks, etc.
Standardization promotion
This case provides a testing model for the hydrogen energy industry chain and promotes the implementation of the national standard "Periodic Inspection and Assessment of Hydrogen Cylinders".
Environmental Value
By extending the service life of hydrogen cylinders and reducing resource waste, we will help promote the sustainable development of the new energy industry under the "dual carbon" goals.
With the core advantages of "precision, efficiency and safety", the VSNDT P series industrial endoscope solves the technical pain points in hydrogen cylinder detection and provides innovative solutions for new energy safety. In the future, with the expansion of the hydrogen energy industry, this type of industrial endoscope technology will play a key role in more scenarios.
