Abstract
Perfeccionamientos en tubos de limpieza, que constan de un tramo tubular, con una boca de limpieza que puede ser cerrada en la que se desemboca desde arriba, caracterizados porque la incorporación y el aseguramiento de posición facilitados de piezas de inserción, por ejemplo con válvulas de retención junto a la mitad periférica del tramo tubular opuesta diametralmente al borde la boca de limpieza, están estructurados dos escalonamientos de diámetro con altura de escalones creciente hacia abajo que discurren transversalmente a la dirección de circulación, y situados uno tras de otro, porque con el primer escalonamiento está asociada en la mitad periférica superior del tramo de tubo una superficie de tope en forma de arco, y porque en la zona del segundo escalonamiento junto al borde interior del tramo tubular o de las paredes interiores de boca de limpieza que se prolongan en ésta, está prevista una ranura de guía que discurre en forma de U transversalmente a la dirección de circulación.
