2024 Elsevier B.V.Cased-hole logging using ultrasonic pitch-catch modality is a proven technique for cement bond evaluation in cased holes. However, complex measuring environments such as tool and casing eccentering makes it difficult to precisely separate and pick the third interface echoes from fu...
Computation of Grain-Noise Scattering Coefficients for Ultrasonic Pitch/Catch Inspections of Metals 来自 ResearchGate 喜欢 0 阅读量: 46 作者:FJ Margetan,L Yu,RB Thompson 摘要: One limiting factor in the detection of internal defects in metals is so‐called "grain noise" which arises from the ...
Non-invasive ultrasonic inspection of sludge accumulation in a pipe 2022, Ultrasonics Citation Excerpt : Kim et al. [3] developed a phased magnetostrictive patch transducer array to focus shear-horizontal waves at any point on a cylindrical surface of a pip for pipe defect inspection. Huan et al...
