Major emphasis is placed on limitations, capabilities, defect detection in coated buried pipes under pressure and corrosion monitoring using different commercial guided wave (GW) systems, approaches to simulation techniques such as the finite element method (FEM), wave mode selection, excitation and collection, GW attenuation, signal processing and different types of GW transducers. The effects of defect parameters on reflection coefficients are also discussed in terms of different simulation studies and experimental verifications.<\/jats:p>","DOI":"10.3390\/s18124470","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T02:15:59Z","timestamp":1545099359000},"page":"4470","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":122,"title":["Detection, Localisation and Assessment of Defects in Pipes Using Guided Wave Techniques: A Review"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6805-4249","authenticated-orcid":false,"given":"Aidin","family":"Ghavamian","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering, Universiti Putra Malaysia, Serdang, Selangor 43400, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faizal","family":"Mustapha","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, Universiti Putra Malaysia, Serdang, Selangor 43400, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3561-0373","authenticated-orcid":false,"given":"B.T Hang Tuah","family":"Baharudin","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Manufacturing Engineering, Universiti Putra Malaysia, Serdang, Selangor 43400, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9922-3647","authenticated-orcid":false,"given":"Noorfaizal","family":"Yidris","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, Universiti Putra Malaysia, Serdang, Selangor 43400, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lin, S., Ito, T., Kawashima, K., and Nagamizo, H.
