AI Technical Summary
Technical Problem
Existing non-destructive testing devices for pipeline welds exhibit decreased detection sensitivity near the base, making comprehensive testing impossible.
Method used
A detection device including a first transverse mechanism and a second transverse mechanism was designed. The pipe is sealed by a sealing plate and an air injection device, and the weld is detected from multiple angles by an ultrasonic probe. The pipe is flipped to achieve full coverage detection.
Benefits of technology
It enables comprehensive non-destructive testing of pipeline welds, improves testing accuracy and sensitivity, and is easy to install and recycle.
