Applications of VSNDT industrial endoscopes in energy and power

VSNDT industrial endoscopes, with their high-precision imaging, flexible inspection capabilities, customization options, and radiation-resistant design, play a crucial role in the installation, operation, maintenance, and fault diagnosis of nuclear power plant equipment, effectively ensuring the safe operation of nuclear power equipment.The following is an analysis of specific application scenarios and advantages of VSNDT industrial endoscopes in nuclear power plants:

Equipment Installation Phase: Pipeline Welding and Foreign Object Detection

Application Scenarios: Nuclear power plants have complex internal structures, with various systems (such as the nuclear island reactor and the conventional island turbine) connected by numerous pipes. During pipeline installation and welding, VSNDT Industrial Endoscopes can detect weld quality in real time, identify defects such as cracks and slag inclusions, and remove residual foreign objects (such as metal debris and welding materials) from the pipes, ensuring that the internal quality of the pipes meets stringent standards.

1. High-Precision Imaging: Utilizes CMOS video imaging technology to clearly present weld details, avoiding missed detections.
2. Flexible Operation: Probe diameters are selectable from 0.95mm to 8mm, adapting to different pipe diameter inspection needs.
3. Non-Destructive Testing: No need to disassemble the pipes, reducing installation costs and time.

Operation and Maintenance Phase: Regular Inspection and Foreign Object Removal

1. Application Scenarios: After a nuclear power plant is operational, a major overhaul is required every refueling cycle. VSNDTIndustrial Endoscopes can be used for:
2. Primary Circuit: Detecting foreign objects (such as fuel debris and sediment) at the bottom of the fuel pool and removing them using gripping tools.
3. Secondary Circuit: Inspect the cleanliness of the pipes after evaporator cleaning and remove any remaining foreign objects.
4. Cooling System: Inspect internal pipe corrosion and foreign object accumulation, guiding cleaning and maintenance.
5. Conventional Island: Inspect the cleanliness of the high and low pressure cylinders of the steam turbine to ensure efficient equipment operation.

Advantages

1. Visual Inspection: Real-time image and video feedback helps operators quickly locate problems.
2. Multifunctional Grabbing Tools: Equipped with alligator-mouth and magnetic tools to meet various foreign object grabbing needs.
3. Long-Distance Inspection: Pipeline lengths can be customized (0.5 meters to 30 meters), covering complex piping systems.

Fault Diagnosis and Preventive Maintenance

Application Scenarios

1. Reactor Vessel: Inspect the furnace top cover for scratches and corrosion using a radiation-resistant endoscope (cumulative radiation resistance 1400Gy), avoiding radiation damage to imaging components.
2. Steam Generator: Detect corrosion in support plates and pipes to prevent leakage risks.
3. Condenser: Inspect circulating water pipes for scale buildup and corrosion, optimizing cooling efficiency.
4. Gearbox and Turbocharger: Detect abnormalities such as missing alloy coatings and peeling of internal surfaces, guiding timely repairs.

Advantages

1. Radiation-Resistant Design: Provides clear images even in high-radiation environments, ensuring reliable detection.
2. High-Precision Measurement: Equipped with 3D stereoscopic measurement technology, quantifies the dimensions of defects such as cracks and dents, providing data support for maintenance.
3. Intelligent Functions: Some models support AI defect recognition, automatically marking cracks or foreign objects, improving detection efficiency.Customized Solutions: Adapting to the Specific Needs of Nuclear Power Plants

Application Scenarios

VSNDT can customize endoscope parameters such as pipeline materials, light source type, and image resolution according to the specific needs of nuclear power plants. For example:

1. For high-temperature environments (such as near reactors), high-temperature resistant probes (withstanding 200℃) are selected.
2. For oily environments (such as lubrication systems), oil-resistant lenses and IP67 protection ratings are adopted.
3. For confined spaces (such as inside gearboxes), ultra-fine probes (diameter ≤ 2.4mm) and 360° omnidirectional tilting capabilities are provided.

Advantages

1. Strong Adaptability: Meets the stringent requirements of the nuclear power industry for testing equipment.
2. Service Guarantee: Provides a 12-month warranty and 4-hour response and 72-hour on-site maintenance services to ensure continuous and stable equipment operation.
