Borescopes for Gas Cylinder Internal Inspection

Why Gas Cylinder Inspections Matter

Gas cylinders are critical for industries ranging from medical oxygen supply and firefighting to industrial gases and SCUBA diving tanks. Over time, the interior surfaces of cylinders can suffer from corrosion, pitting, cracks, or thread damage. If not detected early, these issues may compromise safety, performance, and compliance with international standards.

This is why borescopes are widely adopted to inspect the interior of gas cylinders. With their flexible probes, powerful illumination, and high-resolution imaging, they allow inspectors to identify defects that are invisible to the naked eye.

Applications of Borescopes in Gas Cylinder Inspection

• Thread Inspection – Detect wear, cross-threading, or cracks in cylinder neck threads.
• Corrosion & Pitting – Identify rust or surface damage along cylinder walls.
• Valve Seat Inspection – Ensure the valve connection area remains free of debris or cracks.
• General Surface Integrity – Verify the overall condition of domes, sidewalls, and bottoms.

Types of Borescopes Used for Gas Cylinder Inspections

Based on the references and industry standards, there are several types of borescopes suitable for this task:

• Rigid Borescopes – Provide crystal-clear images, ideal for straight-entry inspections in cylinders with wide openings.
• Flexible Videoscopes – Equipped with articulation, allowing the inspector to navigate bends and thoroughly inspect cylinder threads and domes.
• Dual-View Borescopes – Offer both forward and side views for comprehensive coverage.
• Automated Borescope Systems – Integrated with robotics and AI, capable of 360° spiral scanning and defect detection.

Best Practices for Cylinder Inspections with Borescopes

• Use 8.0–8.5 mm diameter probes for compatibility with cylinder neck openings.
• Choose 180° or 360° articulating tips to cover dome areas.
• Record photos and videos for inspection traceability.
• Integrate results into digital quality certificates (DQC) for compliance and reporting.
