Abstract

MÉTODO DE CONTROLE DE ESTANQUEIDADE E DETECÇÃO DE VAZAMENTO EM UMA TUBULAÇÃO COM UMA VÁLVULA DE FECHAMENTO. A invenção está relacionada ao campo do diagnóstico técnico e pode ser usada para teste de estanqueidade de tubulação e detecção de vazamentos em tubulações de usinas nucleares. Os sinais acústicos são registrados em dois pontos ao longo do comprimento da tubulação e os sinais acústicos recebidos são posteriormente processados. Os sinais acústicos são registrados na ampla faixa ultrassônica em dois pontos ao longo do comprimento da tubulação, localizados na tubulação a montante e a jusante da válvula de fechamento. Os sinais ultrassônicos registrados no ponto da tubulação a montante da válvula de fechamento e no ponto a jusante da válvula de fechamento são então processados, e dois espectros de sinais são traçados a partir dos valores obtidos. Em seguida, a faixa de 15000 a 90.000 Hz é selecionada, e o maior valor de amplitude em ambos os espectros de sinal é escolhido nesta faixa. As amplitudes dos espectros de sinal na faixa de frequência especificada são então divididas pelo maior valor de amplitude e a diferença entre os espectros de sinal antes e depois que o elemento de bloqueio é determinado usando uma fórmula matemática, que proporciona uma determinação da estanqueidade da tubulação para análise de sua capacidade de serviço futuro, bem como a melhoria da qualidade e eficácia da deteção de locais de vazamento na tubulação.
