Abstract

Aparato para ensanchar mediante explosión unos tubos en una placa de soporte de tubos utilizando una cuerda explosiva, incluyendo dicho aparato un elemento de inserción flexible que tiene un diámetro exterior ligeramente inferior al diámetro interno de dichos tubos, una longitud sustancialmente superior al espesor de dicha placa de soporte de tubos, un orificio axial que se extiende desde una extremidad de dichos elemento de inserción y que recibe dicha cuerda explosiva, caracterizado porque la longitud de dicho orificio axial (7) es sustancialmente superior al espesor de dicha placa de soporte de tubos (1) aunque no se extiende completamente a través de dicho elemento de inserción (5) y dicha cuerda (8) se extiende en dicho orificio axial (7) solamente hasta la extremidad de dicha placa de soporte de tubos (1) de modo que se forma un espacio en dicho elemento de inserción (5) delante de dicha cuerda explosiva (8) para recoger los residuos proyectados por dicha cuerda explosiva (8) durantesu explosión.
