Abstract

Método y su correspondiente aparatos para retirar los tubos de un generador de vapor con el fin de cambiarlos, teniendo dicho generador de vapor un cuerpo cilíndrico, una placa de tubos situada en la extremidad inferior de dicho cuerpo cilíndrico, una pluralidad de tubos que se extienden hacia arriba a partir de la placa de tubos y en el interior del cuerpo cilíndrico para formar un haz de tubos en el cuerpo cilíndrico, estando dicho método caracterizado porque incluye las operaciones que consisten en cortar la parte superior del cuerpo cilíndrico separándola de la parte inferior y retirando la parte superior, cortar por lo menos un orificio de grandes dimensiones en el cuerpo cilíndrico en un punto adyacente a la placa de tubos y encima de la misma, cortar los tubos encima de la placa de tubos, situar una pantalla contra radiaciones encima del cuerpo cilíndrico y elevar el haz de tubos en el interior de la pantalla contra radiaciones, cerrando esta última, y en retirar del cuerpo cilíndrico la pantalla de protección contra radiaciones con el haz de tubos y la envoltura en su interior.
