“…Therefore, the objective of this study was to determine the most probable causes for the failure of the LTDS in the Yuanba Gas Field, which were investigated by analyses based on the coupling model, process flow, chemical method, x-ray diffraction (XRD), and energydispersive spectroscopy (EDS). [21][22][23] Additionally, three cleaning solutions were evaluated through weight loss experiments and electrochemical tests. 23,24 This strategy offers a novel perspective in analyzing and solving the failure of LTDS through a simple coupling model and a chemical cleaning method.…”

“…Uma grande variedade de componentes mecânicos metálicos opera em condições severas de temperatura, fluidos corrosivos e em ambientes com a presença de fluxo de partículas e impurezas. Os tubos em uma caldeira são exemplos de aplicações mecânicas onde os materiais sofrem grande desgaste por operarem em temperaturas relativamente altas, ambiente corrosivo e abrasivo devido ao particulado presente no fluido em movimento, o que frequentemente resulta em falhas do componente [1][2][3][4]. Assim, o reforço da superfície de tubulações de caldeiras, pela aplicação de um revestimento, tem sido uma opção bastante interessante para a proteção contra a deterioração por corrosão e o desgaste mecânico [5,6].…”
