Industrial Endoscopes for Gas Turbine Inspection

Gas turbines are vital assets across power generation, aviation and petrochemical sectors. Their performance and reliability directly impact safety, uptime and operating costs. Traditional inspections often require large-scale disassembly, creating long downtimes and high expense. Modern videoscopes (industrial endoscopes) enable non-destructive internal inspection of turbine blades, combustors, nozzles and casings — reducing downtime, enabling early defect detection and improving maintenance decision-making.

What Is a Videoscope (Industrial Endoscope)?

A videoscope is an inspection instrument composed of a camera head (often with adjustable optics), a flexible or rigid probe, integrated illumination and a video display/recorder. It lets technicians insert a probe into otherwise inaccessible areas and capture high-resolution real-time images or video for analysis, measurement and records.

Key Advantages

• Non-destructive inspection — avoids unnecessary component disassembly.
• High-definition imaging & recording for crack detection and documentation.
• Articulating probes (2-way / 4-way / 360°) to navigate complex internal geometries.
• Advanced features: image measurement, stitching, annotation and AI-assisted defect recognition.
• Rugged designs for harsh turbine environments — heat, vibration and dust resistance.

Applications in Gas Turbine Inspection

How to Select the Right Videoscope

When specifying a videoscope for gas turbine inspection, these technical parameters are critical:

• Probe diameter: common sizes 1.3mm – 6mm — choose based on blade gaps and nozzle bores.
• Probe length: from a few meters to >10m depending on stage depth.
• Articulation: 2-way / 4-way / 360° for complex routing.
• Image resolution: 1080p for fine crack detection.
• Illumination: adjustable LEDs or ring lights to handle reflective and dark surfaces.
• Durability: rated for heat, vibration and ingress protection relevant to turbine environments.
• Data & software: recording, measurement tools, annotation, report export and archive capability.

JEET Videoscope Solutions

JEET Videoscope — Shenzhen JEET Technology Co., Ltd. is a leading developer and manufacturer of industrial videoscopes. With more than 50 patents, ISO9001 certification and a global footprint, JEET specializes in solutions for aviation, power generation and industrial NDT.

Recommended JEET Models (Examples)

• JEET T51X Series : ultra-slim probes (as small as ~2.2mm), 4-way articulation — ideal for blade-gap inspections.
• JEET JX Aviation Series: high-resolution optics for combustor and oil-pipe inspection.
• JEET K Series: motor-driven HD videoscopes for long-insertion inspections.

Case Example

In a power-plant inspection case, a JEET T51X videoscope accessed a high-pressure turbine stage and identified a micro-crack at a blade root. The early detection allowed targeted repair without full rotor disassembly, avoiding extended downtime and saving substantial repair costs.
