Abstract

Perfeccionamientos en dispositivos para la verificación de tubos de termocambiador, con un haz de tubos en U, metiéndose una sonda de verificación con una manguera de empuje flexible en un tubo del haz, caracterizados porque la manguera de empuje comprende en su dirección longitudinal, dos partes de diferente flexibilidad, y porque la parte con la mayor flexibilidad está en el lado de la sonda de verificación y es esencialmente más delgada que el tubo y lleva cuerpos de centraje redondeados que circunda en forma de anillo a la manguera de empuje.
