配管エルボ部の欠陥検出におけるガイド波試験の欠陥検出感度の周波数依存性

Guided wave testing offers an efficient screening method for thinning of pipe walls because of its long inspection range and its ability to inspect pipes with limited access. However, the existence of an elbow in pipes makes it difficult to interpret echo signals in guided wave testing. In the prese...
