[0012] FIG. 1 is a perspective view showing part of an industrial air tube according to the present invention;

[0013] FIG. 2 is a perspective view showing another example of the industrial air tube according to the present invention; and

[0014] FIG. 3 and FIG. 4 are perspective views showing other examples of the industrial air tube according to the present invention.

MODE FOR INVENTION

[0015] Reference will now be made in detail to embodiments of the present invention, which are illustrated in the accompanying drawings and described below.

[0016] FIG. 1 is a perspective view showing part of an industrial air tube according to the present invention, FIG. 2 is a perspective view showing another example of the industrial air tube according to the present invention, and FIG. 3 and FIG. 4 are perspective views showing other examples of the industrial air tube according to the present invention.

[0017] As shown in FIG. 1 to FIG. 3, the present invention provides an air tube that is used for pneumatic, painting and piping applications at a variety of industrial sites. A specification indicator 20 is provided on the outer surface of the air tube 10 such that a plurality of air tubes 10 can be easily distinguished such that they have the same specification.

[0018] The specification indicator 20 has a plurality of indicator lines 21 thereon. The indicator lines 21 are linearly marked such that they can indicate the specification of the air tube 10.

[0019] In addition, the indicator lines 21 include a first indicator line 22 which indicates the size of the outer diameter of the air tube 10, a second indicator line 23 which indicates the thickness of the air tube 10, and a third indicator line 24 which indicates the material of the air tube 10.

[0020] Here, the first, second and third indicator lines 22, 23 and 24 are provided with different line thicknesses such that the size of the outer diameter, thickness and the material of the air tube 10 can be easily distinguished.

[0021] In addition, the first, second and third indicator lines 22, 23 and 24 have different colors or line types such that the size of the outer diameter, thickness and the material of the air tube 10 can be easily distinguished.

[0022] Furthermore, it is preferred that the first, second and third indicator lines 22, 23 and 24 be continuously marked on the surface of the air tube 10.

[0023] The indicator lines 21 are formed as straight lines that extend on the surface of the air tube (10). As an alternative, as shown in FIG. 2, the indicator lines 21 are formed as spiral lines. More preferably, indicator lines 21 continue in a variety of shapes such as a curve or a waveform.

[0024] In addition, the specification indicator 20 is painted with a noctilucent material such that the air tube 10 can be easily distinguished at night.

[0025] As shown in FIG. 3, in the air tube 10 according to the present invention, the first, second and third indicator lines 22, 23 and 24 are formed around the outer surface of the air tube 10 such that they can indicate the specification of the air tube 10.

[0026] The first, second and third indicator lines 22, 23 and 24 are provided with different colors, different line thickness and/or different line types such that the size of the outer diameter, thickness and the material of the specification of the air tube 10 can be easily distinguished.

[0027] In addition, it is preferred that the first, second and third indicator lines 22, 23 and 24 be repeatedly provided on the air tube 10.

[0028] As shown in FIG. 4, the air tube 10 according to the present invention has identification codes 30 on the surface such that the specification of the air tube 10 can be indicated.

[0029] Here, it is preferred that the identification codes 30 include numbers or letters that are repeatedly marked.

[0030] A description will be give below of the operating state of the air tube having the above-described configuration according to the present invention.

[0031] Since the specification indicator 20 with which the air tube 10 can be distinguished is provided on the surface of the air tube 10, air tubes 10 having the same size can be easily distinguished by the specification indicator 20 even though a variety of air tubes 10 are mixed.

[0032] In addition, the specification indicator 20 includes the first, second and third indicator lines 22, 23 and 24 that indicate the size of the outer diameter, thickness and material of the air tube 10, and the first, second and third indicator lines 22, 23 and 24 are provided with different thicknesses, line types and colors, such that the specification of each air tube 10 can be more easily distinguished.

[0033] Since at least one of the first, second and third indicator lines 22, 23 and 24 or the identification codes 30 consisting of numbers or letters is formed around the outer surface of the air tube 10 according to the present invention, the identification mark of the air tube 10 can be varied depending on the type and use of the air tube 10, thereby increasing the convenience of the user. In addition, such air tubes have a variety of specifications, and workers can conveniently use the air tubes in works.

[0034] The present invention is not limited to the foregoing certain embodiment. Obviously many modifications are possible to a person having ordinary skill in the art without departing from the scope of the present invention defined in the appended claims, and such modifications shall fall within the scope of the claims.
