Therefore, it is imperative to nondestructively detect and evaluate the external corrosion in nonmagnetic pipes. In light of this, a capsule-type Electromagnetic Acoustic Transducer (EMAT) for in-situ nondestructive evaluation of nonmagnetic pipes and fast screening of external corrosion is proposed in this paper. A 3D hybrid model for efficient prediction of responses from the proposed transducer to external corrosion is established. Closed-form expressions of field quantities of electromagnetics and EMAT signals are formulated. Simulations based on the hybrid model indicate feasibility of the proposed transducer in detection and evaluation of external corrosion in nonmagnetic pipes. In parallel, experiments with the fabricated transducer have been carried out. Experimental results are supportive of the conclusion drawn from simulations. The investigation via simulations and experiments implies that the proposed capsule-type EMAT is capable of fast screening of external corrosion, which is beneficial to the in-situ nondestructive evaluation of small-diameter nonmagnetic pipes.<\/jats:p>","DOI":"10.3390\/s18061733","type":"journal-article","created":{"date-parts":[[2018,5,29]],"date-time":"2018-05-29T06:58:18Z","timestamp":1527577098000},"page":"1733","source":"Crossref","is-referenced-by-count":8,"title":["A Capsule-Type Electromagnetic Acoustic Transducer for Fast Screening of External Corrosion in Nonmagnetic Pipes"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"http:\/\/orcid.org\/0000-0003-4257-2771","authenticated-orcid":false,"given":"Yong","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, Shaanxi Engineering Research Center of NDT and Structural Integrity Evaluation, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Rui","family":"Cai","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, Shaanxi Engineering Research Center of NDT and Structural Integrity Evaluation, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Bei","family":"Yan","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, Shaanxi Engineering Research Center of NDT and Structural Integrity Evaluation, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Ilham Mukriz","family":"Zainal Abidin","sequence":"additional","affiliation":[{"name":"Leading Edge NDT Technology (LENDT) Group, Malaysian Nuclear Agency, Bangi, Kajang 43000, Malaysia"}]},{"given":"Haoqing","family":"Jing","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, Shaanxi Engineering Research Center of NDT and Structural Integrity Evaluation, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Yi","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, Shaanxi Engineering Research Center of NDT and Structural Integrity Evaluation, School of Aerospace Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1016\/j.ndteint.2017.02.001","article-title":"Novel Eddy Current Probes for Pipes: Application in Austenitic Round-in-square Profiles of ITER","volume":"87","author":"Machado","year":"2017","journal-title":"NDT E Int."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1016\/j.ndteint.2015.11.001","article-title":"Thickness Measurement of Metal Pipe Using Swept-frequency Eddy Current Testing","volume":"78","author":"Mao","year":"2016","journal-title":"NDT E Int."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1216","DOI":"10.1016\/j.proeng.2014.03.112","article-title":"Evaluation of Pipe Wall Thickness Based on Contrast Measurement Using Computed Radiography (CR)","volume":"69","author":"Rakvin","year":"2014","journal-title":"Procedia Eng."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"1658","DOI":"10.1016\/j.proeng.2015.12.334","article-title":"Pulsed Eddy Current Testing of Inner Wall Flaws in Pipe under Insulation","volume":"130","author":"Lai","year":"2015","journal-title":"Procedia Eng."},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"975","DOI":"10.3390\/s130100975","article-title":"Applications of Flexible Ultrasonic Transducer Array for Defect Detection at 150 \u00b0C","volume":"13","author":"Shih","year":"2013","journal-title":"Sensors"},{"key":"ref_6","doi-asserted-by":"crossref","first-page":"287","DOI":"10.1016\/j.phpro.2015.08.156","article-title":"Thin Wall Pipe Ultrasonic Inspection through Paint Coating","volume":"70","author":"Predoi","year":"2015","journal-title":"Phys.
