Abstract
Long-term operation in the harsh environment of the tension clamp aluminum tube unpressed area, easy to produce water ingress defects. Based on the reflection characteristics of ultrasound, the optimal detection position, the best detection frequency and the echo characteristics of the internal water inlet in the unpressurized area were studied, and a method for ultrasonic detection of the internal water ingress of the tension-resistant clamp was proposed. The results show that observing the reception time of the primary echo at the water–air interface can determine whether water ingress occurs in the unpressurized area and what the inlet depth is. This method provides a new idea for detecting water ingress inside the tension clamp.
