Abstract

TAPON DE TUBO PARA CERRAR UN TUBO DE TERMOCAMBIADOR DEFECTUOSO Y PROCEDIMIENTO PARA QUITAR EL TAPON DE TUBO, QUE COMPRENDE UNA PARTE (3) CILINDRICA HUECA QUE PASA SIN SOLUCION DE CONTINUIDAD, SIN ESCALON, A UNA PARTE (4) CONICA HUECA. LA PARTE (3) CILINDRICA TIENE UN DIAMETRO EXTERIOR UN POCO MENOR QUE EL DEL TUBO DE TERMOCAMBIADOR (2) A CERRAR. EL TAPON DE TUBO (1) SE INTRODUCE EN EL TUBO DE TERMOCAMBIADOR (2) Y MEDIANTE ENSANCHAMIENTO O BIEN LAMINACION SE LLEVA A CONTACTO HERMETICO CON LA SUPERFICIE INTERIOR DEL TUBO DE TERMOCAMBIADOR (2). EN LA PARTE (4) CONICA SE HAN DISPUESTO MEDIOS (6) PARA INSERTAR UNA HERRAMIENTA (15). LA PARTE (3) CILINDRICA SE HA HECHO RUGOSA EN SU ZONA A ENSANCHAR. EN UN PROCEDIMIENTO PARA SOLTAR EL TAPON DE TUBO (1) SE FUNDE SU PARED POR SOLDADURA EN UNA TRAYECTORIA (12A) PREDETERMINADA, DE MANERA QUE ESTA SE CONTRAE, CON LO CUAL SE SUELTA EL TAPON DE TUBO (1).TUBE PLUG TO CLOSE A DEFECTIVE HEAT EXCHANGER TUBE AND PROCEDURE TO REMOVE THE TUBE PLUG, WHICH INCLUDES A PART (3) HOLLOW CYLINDER THAT PASSES WITHOUT A CONTINUITY SOLUTION, WITHOUT A STEP, TO A PART (4) CONICAL HOLLOW. THE CYLINDRICAL PART (3) HAS AN EXTERIOR DIAMETER A LITTLE LESS THAN THAT OF THE HEAT EXCHANGER TUBE (2) TO BE CLOSED. THE TUBE PLUG (1) IS INTRODUCED IN THE HEAT EXCHANGER TUBE (2) AND THROUGH WIDENING OR WELL ROLLING IT IS TAKEN INTO HERMETIC CONTACT WITH THE INTERIOR SURFACE OF THE HEAT EXCHANGER TUBE (2). IN PART (4) CONICA, MEANS (6) HAVE BEEN ARRANGED TO INSERT A TOOL (15). PART (3) CYLINDRICAL HAS BEEN RUGGED IN ITS AREA TO BE EXTENDED. IN A PROCEDURE FOR RELEASING THE TUBE PLUG (1) ITS WALL IS SOLDERED BY WELDING ON A PRE-DETERMINED PATH (12A), SO THAT IT CONTRACTS, WHICH RELEASES THE TUBE PLUG (1).
