Abstract(s)
O trabalho analisa desvios e falhas em válvulas de segurança e alívio de pressão numa unidade petroquímica entre 2009 e 2024, com foco em 2017-2024. A partir do histórico de intervenções e ensaios em bancada, avaliou-se a adequação dos intervalos de manutenção e a conformidade dos desvios face às práticas do setor. A metodologia baseou-se na recolha e análise de dados de ensaios funcionais, permitindo caracterizar o estado dos dispositivos após serviço. Foram realizados mais de três mil ensaios, revelando desvios frequentes ligados a depósitos e corrosão. Os resultados reforçam a importância dos ensaios e da definição adequada da manutenção.
The study analyses deviations and failures in safety and pressure relief valves in a petrochemical facility between 2009 and 2024, with a focus on 2017–2024. Based on the history of interventions and bench tests, it assessed the adequacy of maintenance intervals and the extent to which identified deviations align with sector practices. The methodology relied on collecting and analysing functional test data, enabling the characterisation of device condition after service. More than three thousand tests were performed, revealing frequent deviations associated with deposits and internal corrosion. The results underscore the importance of testing and of establishing appropriate maintenance intervals.
