Abstract
"PIG RASPADOR ARTICULADO MULTIDIRECIONAL". é descrito um equipamento destinado a ser enviado pelo interior de uma tubulação que apresenta diâmetros internos com diferenças grandes, com a finalidade de promover uma remoção mecânica de incrustações depositadas na parede interna da referida tubulação. O equipamento, é formado, ao menos, por dois módulos vedadores/impulsores (1) e (4) e dois módulos raspadores (2) e (3). Entre os módulos são adaptados meios que permitem um determinado deslocamento angular em relação a um eixo longitudinal comum a eles. O elemento vedador/impulsionador (11) pode ser escolhido dentre cilindros ou discos de espuma de poliuretano ou por vedadores de poliuretano elastómero, desde que suportem a acomodação no interior de tubulações que apresentem diâmetros diferentes. O módulo raspador (2) ou (3) é formado por um conjunto de pares de hastes deslizantes (24) adaptadas a um elemento estrutural central (21) com possibilidade de movimentos de retração ou expansão."Multidirectional articulated scraper PIG". It is described an equipment intended to be sent inside a pipe that has internal diameters with large differences, in order to promote a mechanical removal of scale deposited on the inner wall of said pipe. The equipment comprises at least two sealing / impeller modules (1) and (4) and two scraper modules (2) and (3). Between the modules are adapted means that allow a certain angular displacement in relation to a longitudinal axis common to them. The sealing / booster element 11 may be selected from polyurethane foam cylinders or discs or by elastomeric polyurethane seals provided that they support accommodation within pipes having different diameters. The scraper module (2) or (3) is formed by a set of pairs of slide rods (24) adapted to a central structural element (21) with the possibility of retraction or expansion movements.
