BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water pipe transport structure for connecting a double pipe type metal pipe whose inner surface is protected from a fluid causing corrosion. More specifically, the present invention relates to a connection between a double pipe type metal pipe which may be vulnerable to corrosion. A corrosion resistant human friendly water pipe transport structure is provided.

In general, a water pipe is installed in a building where a person lives to supply tap water necessary for living to a necessary place such as a kitchen or a bathroom. In addition, it may be said that a metal pipe which is preferable in terms of durability because of excellent rigidity than a pipe made of plastic material lacking rigidity may be mainly used.

Metal pipes have a wide variety of characteristics depending on the specific material, and the price also shows a big difference, it is necessary to select and use a metal pipe of a suitable material according to the use. Among them, metal pipes for the purpose of supplying tap water, which may be directly used by humans or used for cooking food, will need to be removed as far as possible from harmful factors. In addition, in view of the life of the building, it will be said that it needs to be excellent in durability.

In order for the metal pipe to be harmless to the human body and to have durability, properties such as water resistance, corrosion resistance, and chemical resistance are required. On the other hand, in the case of a metal pipe that does not have such characteristics, it may be easily corroded or chemically damaged by the fluid, so periodic replacement or rehabilitation is necessary. However, metal pipes made of metals having water resistance, corrosion resistance, and chemical resistance, such as stainless steel pipes, for example, are very expensive, and the use of such expensive metal pipes may be a factor in excessively increasing construction costs. As it is possible, in the past, the use range was inevitably very limited.

In view of such a situation, Korean Patent Application No. 2005-0131652, which is invented by the inventors of the present invention, has provided a “metal pipe whose inner wall is protected by a plastic thin film having a metal coating layer”.

1 is a perspective view showing an example of a double pipe type metal pipe according to the prior art, a metal pipe (hereinafter, 'double pipe type metal, the inner wall is protected by a plastic thin film having a metal coating layer of Patent Application No. 2005-0131652) Pipe ')'.

The double tube type metal pipe 1, as shown in FIG. 1, which can be presented as an example of an improved metal pipe according to the prior art, can be provided very inexpensively while having the required water resistance, corrosion resistance and chemical resistance. Specifically, the plastic pipe 105 may be attached to the inner wall of the metal pipe member 101 to protect the inner wall of the metal pipe member 101 from fluid, and the metal coating layer may be provided on the outer surface of the plastic pipe 105. (103) is formed between the plastic pipe (105) and the metal pipe member (101) by the metal coating layer 103 when attaching the plastic pipe (105) to the inner wall of the metal pipe member (101) using an adhesive (102). To further enhance the adhesion of the.

The metal pipe member 101 constituting the double pipe type metal pipe 1 is not particularly limited in terms of material when it satisfies the required rigidity, and the metal pipe member made of a material lacking corrosion resistance, water resistance, and chemical resistance may be used. Can also be used. In other words, as the inner surface of the metal pipe member 101 is isolated from the fluid by the plastic pipe 105 positioned therein, the metal pipe member 101 may not have the above characteristics. In addition, the material of the plastic pipe 105 is also not particularly limited, but is made of polyethylene, polyester, polycarbonate, etc. in consideration of environmental friendliness.

However, the double pipe type metal pipe as described above, although it is inexpensive in itself and possesses desirable characteristics for water pipe use as it possesses the required corrosion resistance, water resistance and chemical resistance, is installed in a general pipe transportation structure according to the prior art. In this case, the connection part between the metal pipe and the metal pipe is partial, but it is still easy to be exposed to the risk of corrosion due to the difficulty of being completely isolated from the fluid.

Metal pipes can be manufactured according to industrial production methods, and are generally manufactured in a limited length on the basis of a straight shape. Therefore, in the process of being installed inside a building, the metal pipe may be cut to a required length and for length extension. It may be connected to an 'I'-shaped transport structure, or may be connected to an' L'-shaped transport structure to change directions to correspond to the shape of a wall, or may be connected to a 'T'-shaped transport structure for branching.

However, when the metal pipe is installed as a general pipe transport structure according to the prior art, it is not easy to prevent the cross section of the metal pipe from being exposed to the fluid at the connection portion of the metal pipe and the metal pipe, and the 'L' shaped transport structure It is difficult to prevent corrosion by fluid in the existing 'L'-shaped connecting parts or' T'-shaped connecting parts used to implement the 'T'-shaped transport structure.

That is, although the double pipe type metal pipe has been improved to have a cheap and desirable property by attaching the plastic pipe to the inner wall, it is difficult to derive the expected effect in terms of corrosion prevention as long as it is installed with the existing transport structure. This can be called.

The present inventors conducted various studies to solve the above problems, as a result of protecting the cross section of the double pipe type metal pipe formed to protect the inner wall with a plastic pipe from contact with the fluid to prevent the occurrence of corrosion In addition, it was confirmed that the water pipe transport structure can be implemented to prevent corrosion from occurring inside the 'L' or 'T' shaped connecting parts used for connection and to eliminate the possibility of harmful substances being eluted.

Therefore, the present invention, the inner wall is protected by a plastic pipe to improve the corrosion resistance, water resistance and chemical resistance, etc. can be used to connect the double pipe type metal pipe without the risk of corrosion at the connection site, which can be used semi-permanently without the need for replacement and rehabilitation It is an object of the present invention to provide a corrosion-resistant, human-friendly water pipe transport structure that enables the connection work in an easy way.
