发明名称	sistema de detecção de vazamento em dutos encamisados pelo monitoramento do espaço intersticial
摘要	SISTEMA DE DETECçãO DE VAZAMENTO EM DUTOS ENCAMISADOS PELO MONITORAMENTO DO ESPAçO INTERSTICIAL. Na presente invenção é apresentado um sistema de monitoramento de vazamentos em dutos encamisados, também chamados de dutos de parede dupla, através da utilização de um duto de pequeno diâmetro (11) paralelo ao duto encamisado principal e conectado aos respiros (9) instalados em cada tubo encamisado (3) do oleoduto. Esses respiros (9) comunicam o duto de pequeno diâmetro (11) ao espaço intersticial (6) dos tubos encamisados (3) do oleoduto. O duto de pequeno diâmetro (11) pode formar um circuito fechado ou aberto com as centrais de monitoramento e controle (14,14'). O monitoramento de vazamentos pode ser feito através da aplicação de vácuo, de pressão ou pela circulação de um fluido de controle adequado no interior do duto de pequeno diâmetro (11).
