As long as the detection of large-caliber hose is a method to judge its quality, the detection methods are as follows:
1. Large-caliber hoses have a large radius of curvature, which is commonly used for flaw detection by contact methods;
2. For automatic detection, there is also a local water immersion method. For the layered defects of the pipe, a longitudinal wave straight probe or a double crystal longitudinal wave straight probe is used for detection;
3. For radial defects perpendicular to the axis, use oblique probes for axial detection;
4. For radial defects parallel to the bamboo axis, oblique probes are used for circumferential inspection. The longitudinal wave straight probe detection method is similar to forging detection and steel plate detection, and the oblique probe for axial detection is similar to the general transverse wave oblique probe detection.
