The explosion‑proof industrial borescope is a non‑destructive testing device specifically designed for high‑risk environments such as flammable and explosive conditions. Fitted with explosion‑proof enclosures, pressure‑resistant sealing structures and anti‑static materials, they deliver real‑time internal inspections of hazardous pipelines in petroleum, chemical and related sectors without spark generation, ensuring on‑site detection safety. When choosing an explosion‑proof borescope, the key points need to be considered as below
Explosion‑proof certification
When selecting explosion‑proof industrial endoscopes, the primary requirement is that the equipment must hold valid internationally recognized explosion‑proof certifications such as ATEX (EU) and IECEx (International Electrotechnical Commission), and comply with the relevant laws and regulations of the operating region. Operators must clearly identify the explosion‑proof zones and types of explosive gas or dust, and choose equipment with matching explosion‑proof ratings to ensure absolute safety during on‑site inspections.
Probe, host, and battery
The core of the explosion‑proof endoscope lies in its explosion‑proof design. Select probe diameter and insertion tube lengths are based on the inner size of inspection pipelines, with a 360‑degree steering recommended for internal cavities without blind spots. The insertion tube typically requires an anti‑static coating to prevent static sparks generated by friction during rapid pumping. The host is preferably equipped with a high‑strength all‑metal shell with excellent corrosion and impact resistance for long‑term stable service. An anti‑glare, high‑brightness screen is recommended for clear visibility under strong outdoor light. The entire power supply and battery system adopts a dedicated explosion‑proof structure to avoid generating sparks.
Protection ratings
The industrial inspection environment usually accompanied by oil, water vapor, or corrosive liquids. The probe and pipeline insertion cable shall reach at least IP67 or IP68 dustproof and waterproof ratings. For high‑temperature scenarios, choose special customized probes with high temperature protection or air cooling systems is highly recommended.
Practical functions
Explosion proof industrial endoscopes command a higher price than ordinary industrial endoscopes due to their special design and mandatory certification requirements. Select practical features based on your industry and actual needs, such as data storage and defect measurement.
Safety shall be the top priority when purchasing explosion‑proof endoscopes. A model with compliant explosion‑proof certification should be selected based on the on‑site working conditions. Operators must complete professional training to master equipment features and relevant safety operating specifications. On this basis, equipment parameters and functions can be matched as needed to select products that are suitable for the working conditions
FAQ
Q: What certification should the explosion‑proof industrial endoscopes have?
A: Prioritize valid ATEX, IECEx and domestic explosion‑proof certificates matching your hazardous zone classification.
Q: What protection level does the probe need for oily and humid inspection sites?
A: The probe and cable shall reach at least IP67 or IP68 dustproof and waterproof rating.
Q: What design requirements does the host and power supply system need to meet?
A: Explosion‑proof performance is the core design of explosion‑proof endoscopes. The host adopts all‑metal impact‑resistant shell with anti‑glare high‑brightness screen, and the battery power supply adopts full explosion‑proof structure to avoid sparks.
