AI Technical Summary

Technical Problem

Existing technologies for pipeline inspection suffer from problems such as high radiation dose to personnel, high labor intensity, short equipment life, and low inspection efficiency, especially when inspecting weld joints.

Method used

A pipeline internal flaw detection robot was designed, which adopts an ultrasonic detection head and drive system, combined with BIM model interaction to achieve precise detection. The combined movement of the front and rear support legs ensures that the robot slides stably inside the pipeline, reducing radiation dose and extending equipment life.

Benefits of technology

It improves the accuracy and efficiency of pipeline internal inspection, improves the working environment, reduces labor intensity, reduces radiation dose, and extends equipment lifespan.
