Abstract
Disposición para la unión por soldadura de tubos de acero inoxidable que consiste en la deformación de los extremos (3) de tubos rectos (2) hasta alcanzar los extremos (3) un diámetro interno similar a los extremos (4) por su zona externa de tubos curvos (1) o accesorios, siendo introducidos los extremos (4) sobre los extremos (3) y procediéndose a la unión por soldadura (5) mediante un cabezal.Arrangement for the union by welding of stainless steel tubes that consists in the deformation of the ends (3) of straight tubes (2) until the ends (3) reach an internal diameter similar to the ends (4) by their external area of curved tubes (1) or fittings, the ends (4) being introduced on the ends (3) and the welding being joined (5) by means of a head.
Description
Disposición para la unión por soldadura de tubos de acero inoxidable.Arrangement for pipe welding stainless steel.
La presente memoria descriptiva se refiere a una solicitud de una Patente de Invención correspondiente a una disposición para la unión por soldadura de tubos de acero inoxidable, cuya finalidad estriba en lograr a partir de la disposición, la aplicación de la soldadura que genera la unión de los tubos empleados en los circuitos de intercambiadores térmicos.The present specification refers to a application for an Invention Patent corresponding to a provision for welding union of steel tubes stainless, whose purpose is to achieve from the arrangement, the application of welding that generates the union of the tubes used in the exchanger circuits thermal.
Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de circuitos de intercambiadores térmicos y al mismo tiempo, dentro de la industria dedicada a la unión de tubos de acero inoxidable por soldadura.This invention has its application within the industry dedicated to the manufacture of exchanger circuits thermal and at the same time, within the industry dedicated to the union of stainless steel tubes by welding.
Por parte del solicitante se desconoce la existencia o utilización en la actualidad de una disposición para la unión por soldadura de tubos de acero inoxidable similar a la que se describe en esta memoria.On the part of the applicant the existence or use at present of a provision for the welding union of stainless steel pipes similar to that It is described in this report.
La disposición para la unión por soldadura de tubos de acero inoxidable que la invención propone, presenta en su contexto una pluralidad de ventajas que generan la unión inamovible y hermética de los tubos de acero inoxidable empleados en los circuitos de intercambiadores térmicos, consiguiendo obviar problemas posteriores en las uniones realizadas de forma convencional.The arrangement for welding union of stainless steel tubes that the invention proposes, presents in its context a plurality of advantages that generate the immovable union and tightness of stainless steel tubes used in heat exchanger circuits, getting ignored subsequent problems in the unions made in a way conventional.
De forma más concreta, la disposición para la unión por soldadura de tubos de acero inoxidable objeto de la invención está constituida a partir de aumentar el diámetro interior de uno de los tubos que van a ser unidos con el otro, generalmente un tubo curvado por medios convencionales, con objeto de formar el circuito; aumento de diámetro que se realiza utilizando los pertinentes medios conocidos para realizar el aumento del extremo del tubo propiamente dicho, generalmente recto.More specifically, the provision for welding union of stainless steel tubes subject to invention is constituted from increasing the inner diameter of one of the tubes that are going to be joined with the other, usually a tube curved by conventional means, in order to form the circuit; diameter increase that is done using the relevant known means to perform the end augmentation of the tube itself, usually straight.
Una vez aumentado el diámetro hasta conseguir que en la zona interna exista un diámetro similar al diámetro externo del tubo que se introduce, o cualquier otro accesorio, permite la introducción del extremo del tubo o del accesorio dentro del sometido a la ampliación, y posteriormente, con la ayuda de un cabezal de soldadura "TIG" diseñado específicamente para la soldadura de tubos de acero inoxidable, que fija y alinea ambos tubos, se procede a la soldadura, quedando soldado de forma totalmente óptima.Once the diameter has increased until you get that there is a diameter similar to the diameter in the inner zone external tube that is inserted, or any other accessory, allows the introduction of the end of the tube or the accessory into of the submitted to the extension, and later, with the help of a "TIG" welding head designed specifically for the stainless steel tube welding, which fixes and aligns both tubes, welding, being welded so totally optimal
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, un juego de planos en los cuales con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, as an integral part of it, a set of planes in which with an illustrative and non-limiting nature, it has been represented the following:
La figura número 1.- Representa una vista parcialmente seccionada del tubo curvado o accesorio que con posterioridad al mecanizado del extremo del tubo recto va a ser introducido para su pertinente unión por soldadura, configurando el objeto de la invención relativo a una disposición para la unión por soldadura de tubos de acero inoxidable.Figure number 1.- Represents a view partially sectioned from the curved tube or fitting that with after machining the end of the straight tube is going to be introduced for its pertinent welding union, configuring the object of the invention relating to an arrangement for joining by stainless steel tube welding.
La figura número 2.- Refleja una vista de los elementos mostrados en la figura número 1 debidamente acoplados entre sí.Figure number 2.- Reflects a view of the elements shown in figure number 1 properly coupled each.
La figura número 3.- Corresponde a un detalle del objeto mostrado en la figura número 2 debidamente soldados con el pertinente cordón efectuado por el cabezal de soldadura.Figure number 3.- Corresponds to a detail of the object shown in figure number 2 duly welded with the relevant bead made by the welding head.
A la vista de las figuras números 1 y 2, se observa cómo el tubo curvado o accesorio (1) presenta extremos (4) con un diámetro externo similar al diámetro existente en los extremos (3) de los tubos rectos (2), diámetro interno (3) que ha sido obtenido mediante la ampliación del extremo del tubo (2) por medios convencionales, consiguiendo, tal y como se muestra en la figura número 2, que los extremos (4) de los elementos curvos o accesorios (1), queden introducidos en la zona interna de la deformación (3) o ampliación existente en los tubos (2).In view of figures 1 and 2, observe how the curved tube or accessory (1) has ends (4) with an external diameter similar to the existing diameter in the ends (3) of the straight tubes (2), internal diameter (3) that has obtained by extending the end of the tube (2) by conventional means, getting, as shown in the Figure number 2, that the ends (4) of the curved elements or accessories (1), are inserted into the internal area of the deformation (3) or expansion existing in the tubes (2).
Una vez introducidos los extremos, tal y como se muestra en la figura número 2, se procede a la incorporación de la soldadura (5) mediante el cabezal de soldadura "TIG" especial para la soldadura de tubos de acero inoxidable, que fija y alinea ambos tubos, quedando soldados, tal y como se muestra en la figura número 3.Once the ends are introduced, as is shown in figure number 2, the incorporation of the welding (5) using the special "TIG" welding head for welding stainless steel tubes, which fixes and aligns both tubes, being welded, as shown in the figure number 3.
