NEXCO Engineering Co., Ltd. Niigata
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
  1. 画像処理技術により自動で管厚マップを作成
  2. 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
  1. Ultrasound is emitted from the center of the tube through the water.
  2. Detects the reflected echoes from each layer and calculates the thickness of the cast iron pipe based on the time difference
  3. Rotational behavior allows continuous thickness measurement in the circumferential direction
