AI Technical Summary
Existing small-diameter pipe dent defect test blocks have limited dent defect coverage, making it difficult to effectively monitor dent defect signals of various shapes, thus hindering the differentiation and quantitative analysis of dent defects.
A test block and preparation mold for dent defects in small-diameter pipes were designed, including an inner support structure and an outer pressing structure. Through the cooperation of an expansion core, a fixed tie rod and an expansion core shaft, multiple dent defects of different shapes can be formed on small-diameter pipes. Combined with the adjustment of the mold's hardness and position, the accuracy and repeatability of the dent defects are ensured.
This invention enables the arrangement of multiple dent defects on small-diameter pipes, effectively detecting and distinguishing dent defect signals of various shapes. It solves the problem of signal inability to be effectively distinguished in existing technologies and meets the needs of flaw detection.
