Technology to Inspect the Inner Surface of Large Diameter Pipes

Visual inspects inside the large diameter of the pipe to the every corner by a robot equipped with a high-definition camera.

The inner surface of difficult-to-inspect large diameter pipes are inspected with specialized robots. It is possible to visually inspect vertical runs, elbows, and horizontal runs as well as the inner surfaces of large diameter pipes and to expand the range of maintenance support.


  1. Supports pipes with an inner diameter of 500 - 650 mm
  2. Movement inside vertical pipes is possible with self propelled robots
  3. Camera with 10 x optical zoom, pan and tilt function, and flash
