Product Summary
Joint development: Nichizo Tech Co., Ltd.
We have developed "Pipemier i," a device that uses ultrasonic technology to diagnose the degree of deterioration of tunnel disaster prevention main pipes before leakage occurs due to corrosion.
Features/Specifications
Visualization of deterioration
- 画像処理技術により自動で管厚マップを作成
- 管厚マップにより劣化度270°の見える化が可能
Diagnostic equipment configuration
Measurement principle
- Ultrasound is emitted from the center of the tube through the water.
- Detects the reflected echoes from each layer and calculates the thickness of the cast iron pipe based on the time difference
- Rotational behavior allows continuous thickness measurement in the circumferential direction
