Abstract

um pig de tubulação (10) que pode atravessar tubos ou tubulações de diâmetro duplo ou múltiplo tem elementos de vedação retráteis e expansíveis (20) que sustentam o pig, fornecem uma vedação deslizante (dinâmica) com a parede de tubo, e mantêm a pressão necessária para impulsão ou limpeza à medida que os elementos se retraem e se expandem. cada um dos elementos de vedação (20) tem uma cavidade interna (21) dimensionada para alojar um primeiro volume de um fluido e um reservatório (20) dimensionado para alojar um segundo volume do fluido. a cavidade (21) e o reservatório (29) são dispostos de modo que uma porção dos volumes do fluido possa se mover entre cada um dos mesmos. um acumulador (30) mantém uma pressão do primeiro e segundo volumes do fluido de modo que a despeito do tamanho atual do elemento de vedação, ou de se o elemento (20) está em transição entre os tamanhos, o elemento (20) pode manter um engate de vedação deslizante com a parede de tubo (w) e desempenhar a função primária de impulsão ou limpeza (ou ambos).
