## Background
TECHNICAL FIELD
The disclosure relates to a tube comprising a tag and a method of servicing such a tube. More specifically, the method and tube concerns pressurised tubes for fluids and how to service the tube and preferable one or more couplings on the tube.
BACKGROUND
Pressure tubes are normally tubes that can take pressures higher than normal atmospheric pressure, normally up to several thousand times the atmospheric pressure. Such pressurised tubes are subject to strict safety regulations. A faulty tube ejecting high pressure fluid could cut of a limb of staff handling the tube. Tubes must be serviced, e.g. tested and inspected, according to regulations and can only be used for certain purposes, pressures, and time. It is desirable to provide a method to ensure correct and safe service and handling of a tube.
Currently tubes are marked with bar codes, colour labels, sheet metal, or plastic tags with stamped information. Such marking is typically an identification number, a product code, of the tube. It is a technical problem that such marking does not contain enough information and there is no international standard for such information. The information is limited to the physical size of the marked area. It is a technical problem to provide a marking that can be read in many different languages and areas of the world.
A further technical problem is that any marking should also fit and work together with already existing tubes. The marking should be part of the tube, but the cost of a marking is small in relation to the cost of the tube and any of its couplings. Therefore, it is desirable that the marking is not expensive to make. It is further a technical problem to avoid cumbersome arrangement and/or arrangements that are expensive to manufacture.
There is a desire to be able to provide a marking to a tube that can be read from the tube at different places along the tube. A marking is fixed to the tube at a certain position and that position may not be viewable because of the environment that the tube is in. For example, the part of the tube with the marking is inside a machine and therefore the marking can not be read.
The present invention is directed to overcoming one or more of the problems as set forth above.
SUMMARY
It is an object of the present invention to provide a tube, with one or more couplings, comprising a tag and a method for servicing such a tube with one or more couplings. This object can be achieved by the features as defined in the independent claims. Further enhancements are characterized in the dependent claims.

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings illustrate presently preferred exemplary embodiments of the disclosure, and together with the general description given above and the detailed description of the preferred embodiments given below, serve to explain, by way of example, the principles of the disclosure.
FIG. 1 is a diagrammatic illustration of a tube according to an exemplary embodiment of the present disclosure.
FIG. 2 is a diagrammatic illustration of a tube according to an exemplary embodiment of the present disclosure.



DETAILED DESCRIPTION
FIG. 1 illustrates schematically a tube (10) with a coupling (12, 14) at each end. The tube (10) may be a pressurised tube (10). The pressure may be higher than the atmospheric pressure. For example, the tube (10) may be a high pressure tube (10) for several thousand times the atmospheric pressure, e.g. more than 350 bar. The couplings (12, 14) may be quick connect couplings (12, 14) allowing a fluid source to be connected to, for example, a tool by the tube (10). A cylinder (20) may be arranged around the tube (10). The cylinder may be slidable arranged on the tube (10). The cylinder (20) may comprise a tag (30). The tag (30) may be a near field communication (NFC) tag (30). While only one tag (30) is illustrated, the tube (10) may comprise a plurality of tags (30). In FIG. 1 the cylinder (20) is, as an example, a transparent piece of tube arranged around the tube (10) and is limited by the couplings (12, 14) so that the tag (30) can not be separated from the tube (10).
FIG. 2 illustrates schematically a cut in the radial direction through the cylinder (20), the tag (30), and the tube (10) viewed along the axial direction of the tube (10). It may be taken from FIG. 2 that there is space between the cylinder (20) and the tube (10) and this allows the cylinder (20) to move along the tube (10) in its axial direction. Hereby the tag (30) can be moved along the tube (10) to a convenient location along the tube (10) so that the tag (30) can be accessed. In this way tag (30) can be moved to a suitable place along the tube (10) so that data can be read of the tag (30) and/or data can be written to the tag (30). The tag (30) may be located on the inside of the cylinder (20) so that the tag (30) is protected.
According to one embodiment, a tube (10) comprises a tag (30) as illustrated in FIGS. 1 and 2. The tag (30) comprises tube service data and at least one more data of the following group of data: tube identification data, tube manufacture data, and tube operation data. The tag (30) allows the data to be read, written, and updated electronically. The tag (30) provides data for servicing the tube (10).
According to one embodiment, the tag (30) may be a radio-frequency identification (RFID) tag or a near field communication (NFC) tag. The tag (30) may be an active tag, or a semi active tag, or a passive tag. The tag (30) may be read or written to using conventional means such as a mobile phone. The tag (30) can be read or written to or updated directly. In this way all the data is on the tag (30). The tag (30) can be read or written to or updated indirectly. In this way all, or some of, the data is on the tag (30). The tag (30) may for example provide a URL link to further data and the possibility to update such further data.
According to one embodiment, the tube (10) may further comprises one or more couplings (12, 14), and the tag (30) may further comprise data for servicing the one or more couplings (12, 14) and at least one more data of the following group of data: coupling identification data, coupling manufacture data, and coupling operation data. The tag (30) may further provide data for servicing the one or more couplings (12, 14) as an alternative or in addition to the tube (10).
According to one embodiment, the tube (10) may be a pressurised tube. The pressure may be higher than atmospheric pressure. For example, the tube (10) may be a high pressure tube (10) for several hundred or thousand times the atmospheric pressure. For example, the tube and one or more couplings may be configured for more than 350 bar.
According to one embodiment, the tag (30) is arranged on a cylinder (20), the cylinder surrounding at least a part of the tube (10). The cylinder (20) may be in the shape and form of a sleeve. The cylinder (20) may be able to slide along the tube (10). The cylinder (20) may for example be a transparent piece of tube. The cylinder (20) may be part of a protective cover for the tube (10) that covers, for example, the entire length of the tube (10). The cylinder (20) may be limited by the couplings (12, 14) so that the cylinder (20) can not be removed from the tube (10). In this way the cylinder (20) is attached to the tube (10) by the tube (10) itself and the couplings (12, 14).
According to one embodiment, the tag (30) may be arranged on the inside of the cylinder (20). This arrangement is to protect the tag (30). In this way the tag (30) can be protected from the environment that the tube (10) is used in. In one embodiment, the tag (30) can be embedded in the cylinder (20). In one embodiment, the tag (30) may be arranged to the tube (10) by the use of adhesive tape, pressure sensitive tape. The adhesive tape may be illustrated by feature (20) in FIGS. 1 and 2.
According to one embodiment, the tag (30) and cylinder (20), or either the tag (30) or the cylinder (20), or the adhesive tape, comprise distinct visual text and/or markings. Such distinct visual text and/or markings may identify the tag (30) and inform, visually, a user of the existence of the tag (30). For example, the cylinder (20) may be made out of a fluorescent material. For example, the cylinder (20) may have a distinct colour, such a bright orange or red, so that it is easily noticed by a user of the tube (10). For example, the cylinder (20) may have a text written on it, such as “READ ME BEFORE USE”, max pressure allowed, and/or expire date. By providing a distinct visual text or marking on the tag (30) or the cylinder (20) a user notice that there is important information and where it is.
By servicing a tube and/or couplings is meant very broadly taking care of and maintaining the tube and/or couplings. To service a tube, especially a pressurised tube, is very important to ensure proper working of the tube. The same applies for the one or more couplings to the tube. With this tag and the service data stored on the tag (comprised by the tube) the possibility to service and to ensure such service is technically solved. This includes, for example, making optical inspections of the tube and/or couplings. This includes, for example, making pressure tests of the tube and/or couplings. Such service may be prescribed and defined by law and health and safety regulations. The technical effect of having service data on a tag on the tube and/or couplings allows a user of the tube and couplings to, for example, know and ensure what service has been done, what and how and when service needs to be done. The technical improvements and effects alone with regard to health and safety are considerable and can be ensured by at least one embodiment described herein.
According to one embodiment, the service data is data relating to servicing the tube. The service data may also, or alternatively, relate to servicing the one or more couplings. Such service data may comprise:

Servicing the tube (10) and/or the at least one or more couplings (12, 14) may be done according to the data read and the instructions read. This makes it technically possible to service the tube and/or couplings because the data for servicing is available with the tube (10). The instructions, such as how and when, to do the service can be taken from the tube (10) via the tag (30). The results of the service can then be added to the tube (10). It may be possible to always check the tube (10) to ensure that the tube (10) is in order and complies with all its requirements. Further technical advantages from having service data, identification data, manufacture data, and/or operation data have been disclosed above.
According to one embodiment, reading and writing data to or from the tag (30) is done directly to the tag (30), or indirectly via the tag (30) to a remote memory. The remote memory can be part of a free standing computer, mobile phone, hand held computer device, or terminal that can display the data on the tag (30). This may allow for links to the remote memory, for example via the use of a URL, where data can be read and/or written and/or updated.

At least one embodiment ensures controlling a tubes identification, manufacturing documentation, guide to where and how to order a new one. Tracking is ensured and service maintenance. At least one embodiment ensures complete traceability of information about the hose and its manufacturer in multiple languages. It is thus possible to store all necessary information in several languages for tubes and/or couplings sold worldwide. At least one embodiment allows a user to scan or read data using a mobile phone and then quickly via SMS or email to order a replacement tube and/or couplings.
At least one embodiment provides a tag attached to a tube, a hose, that can not readily be removed or be affected by external factors such as weather, sun, or dirt. The tag allows reading and writing the tag in the environment where the tube is installed. The tag can be moved to a suitable place for that purpose along the tube.
At least one embodiment allows a user or a manufacturer, at any time, check the tube, the hose, using a mobile phone by holding the mobile phone over the tag that is attached to the hose. The mobile phone communicates wirelessly with the tag and collects all data concerning the tube and/or couplings. A mobile phone, or any other reader, may activate the tag.
At least one embodiment allows the collected data to be accessed. Such data may include, for example, data concerning the tube part number, length of the hose, threaded connection, the manufacturer's phone number, address, etc.
At least one embodiment allows to identify and compile information and data to a tube that is not new, but has been previously sold. In this way tubes can be subsequently labelled. It has become increasingly common in recent times to duplicate tube and tube products, such as couplings for example. For a user it is difficult to see what is an original tube and coupling and what is a copy. At least one embodiment allows to create an identification function that covers the whole world and that would prevent copying the tube and tube products.
As previously mentioned, the disclosure is not limited in its application with respect to a certain type of tube or hose, but can be applied to many other areas such as gas tubes, compressed air tubes, breathing air tubes, oil tubes, and tubes for acid.
At least one embodiment may provide a method for checking identification information and the like for a tube comprising a tag. The tag comprises all data about the tube and the company that manufactured the tube. After having placed the tube with the tag near a reader, information carried by the tag is received. The information may be stored in a database so that a user can get all the necessary data required for service, replacing the tube, and ordering a new tube.
