Abstract

1.Aparato para dilatar hidráulicamente un tubo para acoplarlo con una placa de tubos, incluyendo dicho aparato un mandril que tiene un diámetro externo inferior al diámetro interno de dicho tubo con el objeto de formar una cavidad anular ente el tubo y el mandril cuando el mandril está introducido en dicho tubo, teniendo dicho mandril en una extremidad un orificio de entrada de fluido que asegura la comunicación del fluido con dicha cavidad anular, teniendo dicha extremidad un saliente que se extiende radialmente hacia el exterior más allá del diámetro interno de dicho tubo, un surco circunferencial adyacente a dicha primera extremidad de dicho tubo para recibir un primer dispositivo de estanqueidad que forma una junta estanca a los fluidos adyacentes a dicha primera extremidad de dicho tubo para recibir un primer dispositivo de estanqueidad que forma una junta estanca a los fluidos adyacente a dicha primera extremidad de dicha cavidad y un segundo dispositivo de estanqueidad situado en laotra extremidad de dicho mandril para asegurar la estanqueidad de la otra extremidad de dicha cavidad, caracterizado porque dicho mandril (11) tiene una porción cónica (27) en su otra extremidad cuyo extremo más ancho es adyacente a dicha otra extremidad y porque se han previsto unos medios (31) para orientar dicho segundo dispositivo de estanqueidad (15) hacia la otra extremidad de dicho mandril (11) con el fin de obtener una junta hermética a los fluidos adyacente a cada extremidad del espacio anular (17) permitiendo al mismo tiempo que dicho mandril (11) se deslice fácilmente en dicho tubo (5) sin deterioración del dispositivo de estanqueidad situado en dicha otra extremidad en el interior de dicho tubo (5).
