Industrial Pipe Wall Inspection Tool | Minimum Fit Φ8mm Pipe Diameter | Dedicated Non-Destructive Testing Equipment for Pipe Walls
The EZON EZ-EN40SV-RT features a side-view optical solution, emphasizing close-focus high definition and an ultra-wide viewing angle. The probe can smoothly enter narrow pipes with a minimum inner diameter of 8mm, providing 90° side imaging without the need for repeated probe adjustments. Specifically designed for industries such as precision equipment, industrial castings, shipbuilding, and pressure vessels, it offers a one-stop solution for detecting internal pipe corrosion, cracks, weld defects, blockages, and foreign objects, achieving non-disassembly, non-destructive, and visually efficient inspection.

Product Features
✅Dedicated Close-Focus Optics for High-Definition Defect Identification at Close Range:
The lens optics system is optimized for close-focus operation, with a minimum observation distance of 5mm. It clearly captures minute cracks, pinholes, weld beads, and burrs on the pipe wall without blurring, and clearly identifies micron-level defects, eliminating missed detections and misjudgments.
✅140° Wide-Angle Side View for Wider Pipe Wall Coverage in a Single Insertion:
The 140° wide-angle side view design significantly expands the observation range compared to conventional side-viewing endoscopes. It halves the number of steps required to observe the pipe wall, significantly improving inspection efficiency. There are no blind spots in the observation of bent pipes and pipes with varying diameters.
✅Minimal Access Size, Can Reach Pipes as Small as Φ8mm
The probe has strong outer diameter adaptability, allowing insertion into pipes with an inner diameter as small as 8mm.
✅ 90° Fixed Side-View Structure, Dedicated for Pipe Wall Inspection
Side-mounted vertical pipe wall imaging eliminates the need to rotate the probe to adjust the observation angle. Simply align the probe with the pipe wall to directly observe typical pipe wall defects such as longitudinal/circumferential cracks, inner wall thinning, and weld incomplete fusion, offering far greater targeting than direct-view endoscopes.
✅ IP67 Protection for the Entire Probe, Stable Operation in Harsh Conditions
The probe and insertion pipeline are IP67 waterproof, oil-proof, dustproof, and acid/alkali resistant, ensuring stable imaging even in environments with oil, water, moisture, and dust.
✅Complete Data Retention, Traceable Inspection Reports
USB interface, compatible with Windows systems above XP and some Android systems, but not iOS. Real-time screen preview, local storage of photos, videos, and images, with exportable archives to meet quality inspection and maintenance archiving requirements.
✅ Lightweight, handheld, integrated design for independent single-person operation.
The portable, integrated design allows for immediate use without external auxiliary equipment. Single-person deployment and testing are possible, significantly reducing downtime and overall maintenance costs.
