Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe body for pipes or the like having an anticorrosion treatment on its end, and an anticorrosion sheet used for performing the anticorrosion treatment on the pipe body.

[0002]

[Prior art]

 As is well known, this seed tube is appropriately cut into desired dimensions at the time of its use, but corrosion such as rust is likely to occur on the cut surface. Therefore, in the conventional case, the cut surface is quick-drying, for example. The anticorrosion treatment is achieved by applying the paint.

[0003]

[Problems to be solved by the device]

 However, with the conventional anticorrosion means using paint, even with a quick-drying paint, it takes several hours to dry, and the tube cannot be used until it dries. It was one of the reasons for delaying a series of work at the site.

Therefore, the present invention has been made in order to solve the above-mentioned problems of the related art, and can easily perform the anticorrosion treatment of the pipe body, thereby contributing to the efficiency of the work of a series of pipes and the like. This is an issue.

[0005]

[Means for Solving the Problems]

 That is, in order to solve the above problems, the present invention is provided with the anticorrosion sheet 5 through the rubber adhesive 3 on the tip surface 6b of the tube body 6a in order to prevent corrosion of the tip surface 6b. This is a pipe for piping.

Further, the anticorrosion sheet according to the present invention is an anticorrosion sheet provided on the front end surface 6b of the tubular body 6a in order to prevent the front end surface 6b of the tubular body 6a from corrosion. Further, a rubber-based adhesive 3 capable of adhering to the tip surface 6b of the tubular body 6a is provided.

[0007]

[Action]

 Therefore, in the pipe body for piping or the like characterized by the above structure, the anticorrosion sheet 5 is provided at least on the tip surface 6b of the pipe body 6a through the rubber adhesive 3. The rubber-based adhesive 3 protects the tip surface 6b of the tubular body 6 from corrosion, and the anticorrosive sheet 5 protects the rubber-based adhesive 3 and the tip surface 6b of the tubular body 6a. The anticorrosion state can be maintained.

【Example】

 An embodiment of the anticorrosion sheet according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a thin-walled anticorrosion sheet body made of a metal such as stainless steel or copper. The anticorrosion sheet body 1 has a desired length according to the pipe diameter of the pipe body to be anticorrosion. It has a plurality of cuts 2 formed at a predetermined interval on one side thereof, and a rubber adhesive 3 is provided on the back side as shown in FIG. The release material 4 is adhered.

The anticorrosion sheet according to the present embodiment has the above-mentioned configuration. When using this to perform anticorrosion treatment on the end portion of a tubular body such as a ductile pipe, the following is performed. Then do.

First, as shown in FIG. 2A, the release material 4 is peeled off from the rubber-based adhesive 3 of the anticorrosion sheet 5, and the other side is cut into a predetermined size at the end of the tubular body 6. After bonding the entire circumference of the outer peripheral surface, bend one side with the notch 2 as shown in Fig. 2B, and bond from the tip surface 6b of the pipe body 6a to the inner peripheral surface of the end. is there.

As a result, the anticorrosion treatment of the end portion of the pipe body 6 is completed, but since the anticorrosion sheet 5 is simply bonded to the end portion of the pipe body 6, the work is extremely simple and It has the advantage that it can be performed quickly, and can be used as piping immediately after such anticorrosion treatment, which can greatly contribute to the efficiency improvement of a series of operations in the field.

Further, since a large number of notches 2 are provided on one side of the anticorrosion sheet body 1, the bonding work from the tip surface 6b of the tubular body 6a to the inner peripheral surface of the end can be easily performed. There are advantages that can be achieved.

In this way, the end portion of the tube body 6 to which the anticorrosion sheet 5 is adhered is preferably corroded by the rubber-based adhesive 3 of the anticorrosion sheet 5, and the anticorrosion sheet body 1 is Since it is made of metal, not only the end portion of the tubular body 6 but also the rubber-based adhesive 3 is protected, and a good anticorrosion state by the rubber-based adhesive 3 is maintained for a long period of time.

Further, since the anticorrosion sheet 5 according to this embodiment has a very simple structure, there is an advantage that the anticorrosion sheet 5 can be manufactured easily and at low cost.

In the above embodiment, the linear cut 2 is provided on one side of the anticorrosion sheet body 1, but the concrete shape of the anticorrosion sheet body 1 is never It is not limited to this. For example, as shown in FIG. 3 (a), a notch 2 may be provided on one side of the anticorrosion sheet body 1 so that a plurality of chevron portions 1a are formed, or As shown in FIG. 6B, the ridge 1a may be provided with a fold 7 such as a small hole having a width corresponding to the thickness of the tip surface 6b of the tubular body 6a. The work of adhering the sheet 5 becomes simpler.

Further, in the present invention, since it is sufficient that at least the tip surface 6b of the tubular body 6a can be protected from corrosion, a simple ring-shaped anticorrosion sheet 5 is attached to the tip surface 6b via the rubber adhesive 3. May be configured by

[0018]

[Effect of the Invention] As described above, according to the present invention, the anticorrosion treatment of the tip surface can be achieved by the extremely simple work of installing the anticorrosion sheet on the tip surface of the pipe body through the rubber adhesive. Since pipes can be used as piping immediately after the anticorrosion treatment is completed, it is necessary to dry the paint after the anticorrosion treatment by coating the paint. Without delaying the work, we have achieved a special effect that can greatly contribute to the efficiency improvement.

Further, as described above, the anticorrosion sheet according to the present invention has a very simple overall structure, so that it has a practical effect of being easily and inexpensively manufactured.
