Metallographic Aspects Investigation of Penstock Materials in Hydroelectric Power Plants and Penstock Maintenance MethodsTaşgın, YahyaKahraman, GökhanEnerji ve Yakıtlarİnşaat MühendisliğiMalzeme Bilimleri, Özellik ve TestÇevre MühendisliğiHydroelectric power plants are renewable energy sources and have little impact on the environment.Therefore, it is one of the most preferred energy sources in the world. In parallel with this situation, it isvery important that the hydroelectric power plants are maintained, their failures are prevented orpermanently removed. One of the most important parts of hydroelectric power plants is penstock pipes.Along with the snail part of the power plant, the penstock supplies the pressurized water to the turbinewheel for energy production. In the power plants that have been producing energy for many years, themaintenance and material properties of penstock are very important. In this study, one of the most importantequipment of hydroelectric power plants, pressurized water pipes (penstock) and chemical componentshave been examined in macro and micro structure and their maintenance is investigated. In themetallographic study on the samples taken from two different regions of the penstock pipe; the perliticstructure, which has a homogeneous distribution into the ferritic structure forming the matrix, is determinedand supported by analyzes. This study will help to ensure that all hydroelectric power plants operatesmoothly in terms of penstock.2019Articlehttps://rdlopen.rawdatalibrary.net/r/munzur/5210https://doi.org/10.16984/saufenbilder.5326741301-4048enSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisiinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/5210
