TUBO FLEXIBLE PARA GAS Y AGUAFLEXIBLE TUBE FOR GAS AND WATER

CAMPO TÉCNICOTECHNICAL FIELD

El objeto de la presente invención, tal como se expresa en el enunciado de esta memoria descriptiva, hace referencia a un tubo de acero inoxidable corrugado con capacidades mejoradas de estanqueidad en sus conexiones y que permite su reciclado al finalizar su ciclo de vida útil sin necesidad de separar sus componentes.The object of the present invention, as expressed in the wording of this specification, refers to a corrugated stainless steel tube with improved sealing capabilities in its connections and that allows its recycling at the end of its useful life cycle without the need for to separate its components.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Actualmente, la conducción del gas y agua en sistemas ACS (agua caliente sanitaria) se realiza mediante tubos flexibles realizados a partir de un núcleo de goma recubierto por una malla de acero, que presenta en sus extremos una pieza de latón que sirve para empalmar los tubos o unirlos a los dispositivos propios de la instalación. Esta pieza metálica es comúnmente denominada racor o conector.Currently, the conduction of gas and water in DHW systems (sanitary hot water) is carried out by means of flexible pipes made from a rubber core covered by a steel mesh, which has a piece of brass at its ends that serves to connect the tubes or join them to the devices of the installation. This metal piece is commonly called a fitting or connector.

El racor o conector se constituye a su vez por un niple asociado herméticamente a la tubería de goma mallada, que en el caso de tratarse de una conexión macho se prolonga en un tramo fileteado exteriormente sobre el que es susceptible de roscarse la tuerca del conector complementario al que ha de unirse. Por el contrario, si se trata de un niple hembra, incorpora la tuerca, que gira libremente sobre el niple, retenida por un ensanchamiento anular previsto en el extremo del niple.The fitting or connector is in turn constituted by a nipple hermetically associated with the mesh rubber tubing, which in the case of a male connection is extended in an externally threaded section on which the nut of the complementary connector can be screwed. to which he has to join. On the contrary, if it is a female nipple, it incorporates the nut, which rotates freely on the nipple, retained by an annular widening provided at the end of the nipple.

Este tipo de tubo no es reciclable ya que incorpora piezas de tres materiales no siendo posible separar sus componentes al finalizar su vida útil.This type of tube is not recyclable since it incorporates pieces of three materials and it is not possible to separate its components at the end of its useful life.

Por consiguiente, esta técnica no es apropiada para el reciclado de estos elementos al final de su vida útil, entrando en conflicto con los actuales sistemas de economía circular, que tienen como objetivo reducir tanto la entrada de los materiales vírgenes como la producción de desechos, cerrando los «bucles» o flujos económicos y ecológicos de los recursos. Consequently, this technique is not appropriate for recycling these elements at the end of their useful life, coming into conflict with current circular economy systems, which aim to reduce both the entry of virgin materials and the production of waste, closing the "loops" or economic and ecological flows of resources.

Existen otros tipos de tubos realizados enteramente en acero, conformados por un tramo de tubo corrugado de acero a cuyos costados se sueldan dos racors macho/hembra, según la necesidad, que sí podrían ser reciclados al no mezclar materiales diversos, sin embargo, la soldadura necesaria para su montaje es compleja de realizar y debe ser testeada posteriormente a su realización. There are other types of tubes made entirely of steel, made up of a section of corrugated steel tube to whose sides two male / female fittings are welded, according to need, which could be recycled by not mixing different materials, however, welding necessary for its assembly is complex to carry out and must be tested after its realization.

Sería deseable el desarrollo de un tubo corrugado de acero inoxidable con una técnica constructiva que se adaptase al sistema de economía circular sin que ello implique una fabricación más compleja.It would be desirable to develop a corrugated stainless steel tube with a construction technique that adapts to the circular economy system without implying a more complex manufacturing.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

Con el fin de superar este inconveniente, se ha diseñado el nuevo tubo flexible para sistemas ACS objeto de la presente memoria técnica.In order to overcome this drawback, the new flexible tube for ACS systems object of the present technical specification has been designed.

En términos generales, la presente invención se refiere a un nuevo tubo de acero inoxidable corrugado válido para instalaciones de gas como de agua, que presenta como ventaja estar realizado en un único material, tanto los racor como la manguera, realizándose su acoplamiento sin la necesidad de soldaduras, lo que permite su reciclado y de esta forma su integración en sistemas productivos circulares.In general terms, the present invention refers to a new corrugated stainless steel tube valid for gas and water installations, which has the advantage of being made of a single material, both the fittings and the hose, making their coupling without the need of welds, which allows its recycling and thus its integration into circular production systems.

Concretamente el nuevo tubo flexible de gas y agua está constituido por un tramo recto de tubería corrugada de acero inoxidable que presenta en ambos extremos un niple hembra o macho, según la necesidad, también realizado en acero inoxidable, donde dicho niple presenta un tramo tubular de diámetro ligeramente superior al de las crestas del tubo corrugado, en cuyo interior está insertado el extremo de la tubería corrugada, con la interposición de una o varias juntas tóricas que se alojan en los espacios delimitados por dos crestas contiguas, sellando el paso entre la superficie exterior del tubo corrugado y la superficie interna del niple. Al mismo tiempo, el tramo tubular del niple presenta una reducción anular de su diámetro en coincidencia con el espacio delimitado por las siguientes dos crestas contiguas a las que contienen la junta tórica, que fija el racor en su posición de uso, sin posibilidad de que este se desacople accidentalmente.Specifically, the new flexible gas and water tube consists of a straight section of corrugated stainless steel pipe that has a female or male nipple at both ends, depending on the need, also made of stainless steel, where said nipple has a tubular section of diameter slightly greater than that of the ridges of the corrugated pipe, into which the end of the corrugated pipe is inserted, with the interposition of one or more O-rings that are housed in the spaces delimited by two contiguous ridges, sealing the passage between the surface outside of the corrugated tube and the inside surface of the nipple. At the same time, the tubular section of the nipple presents an annular reduction in its diameter in coincidence with the space delimited by the next two ridges contiguous to those containing the O-ring, which fixes the fitting in its position of use, without the possibility of it it accidentally disengages.

El montaje del nuevo tubo flexible es muy simple. En primer lugar, se inserta una junta tórica en el espacio comprendido entre las dos cresta finales de cada extremo de la tubería corrugada de acero inoxidable. Seguidamente los extremos de la tubería con las juntas tóricas incorporadas se insertan en el interior del tramo tubular de cada niple de acero inoxidable una profundidad correspondiente como mínimo a tres crestas del tubo de acero, aunque podrían ser más si se utilizan más de una junta tórica por racor.The assembly of the new flexible tube is very simple. First, an O-ring is inserted into the space between the two end ridges at each end of the corrugated stainless steel pipe. The ends of the pipe with the incorporated O-rings are then inserted inside the tubular section of each stainless steel nipple a depth corresponding to at least three ridges of the steel tube, although they could be more if more than one O-ring are used. by fitting.

Finalmente, con el extremo del tubo corrugado insertado en el niple, se estrangula el tramo tubular del niple contra la superficie externa del tubo corrugado mediante una herramienta apropiada, creándose a la vez la reducción anular de su superficie que queda insertada en el espacio comprendido entre las dos crestas contiguas a las que contienen la junta tórica, con lo que la tubería queda afianzada al niple.Finally, with the end of the corrugated tube inserted into the nipple, the tubular section of the nipple is constricted against the external surface of the corrugated tube by means of an appropriate tool, creating at the same time the annular reduction of its surface that remains inserted in the space between the two ridges adjacent to those containing the O-ring, thereby securing the pipe to the nipple.

Así pues, todos los elementos del novedoso tubo flexible están realizados en un único material (acero inoxidable) por lo que puede ser enteramente reciclado, y carece de soldaduras en su montaje por lo que su fabricación es más sencilla.Thus, all the elements of the new flexible tube are made of a single material (stainless steel) so it can be entirely recycled, and it does not have welds in its assembly so its manufacture is simpler.
