Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corrosion-

More particularly, the present invention relates to an embedding pipe and a fitting for preventing corrosion, and more particularly, to an embedding pipe and a PE coating layer formed on the outer periphery of a joint where the pipe is bound at both sides, To block the exposed portion of the fitting and to block the gap with the pipe.

In general, pipe joints for jointing pipes used in water pipes and the like have various shapes and various materials. In order to connect the piping, most of the joints are provided with a separate cap or the like on the body of the joint so that the piping is connected by screwing the cap.

In the case of such a joint, there is a problem in that the construction is difficult because a separate connecting tool or the like used for assembling must be used. Therefore, it is urgently required to develop a joint that can be easily joined by piping without a separate tool, and Korean Patent Application No. 2009-178 (entitled "Jointless wedge type socket joint") was provided.

However, in the case of these joints, since they are manufactured using the casting structure, the manufacturing cost is high, and there is a possibility that a difference in thermal strain between the pipe and the piping completed by the extrusion method may occur.

Therefore, a pipe-type joint which is made of the same material as the pipe for pipes and which makes one side of the metal pipe to be enlarged in a way that the manufacturing method is easy and productivity can be improved is disclosed in Korean Utility Model Application No. 2010-7223 : A press-fit metal pipe fitting with excellent compression force). In order to connect the metal pipe, one side of the metal pipe is expanded, a rubber ring and a metal ring for watertightness are implanted inside the expanded pipe, a part of the metal pipe for pipe connection is inserted, And a pipe fitting is tightly coupled to the metal pipe fitting.

However, in such a case, there is a problem in that a separate tool is necessary because pressure must be applied to the expanded portion of the metal pipe to fit the inserted pipe by using a separate press tool. In addition, when the repair work or the like is carried out, since the pressed connection part can not be separated, the joint itself must be removed or the entire pipe must be replaced.

These prior arts use stainless steel piping or PE pipe piping which is resistant to corrosion. When they are used for landfill, that is, for landfill piping, depending on the landfill environment, The corrosion of the pipe pipe is more likely to occur, and the PE pipe pipe has a relatively low durability (aged deterioration, low-temperature impact resistance) as compared with the stainless pipe, and the life of the PE pipe pipe is shortened.

SUMMARY OF THE INVENTION The present invention has been conceived in order to solve such a conventional problem, and it is an object of the present invention to provide a method of manufacturing an injection molding machine, which comprises a filling pipe and a coating layer of PE material on the outer periphery of the fitting, And the sealing member is combined with the sealing member so as to block exposed portions at both ends of the fitting, and to prevent the corrosion at the time of filling by intercepting the gap with the filling pipe.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a stapler comprising: a metal fitting having both sides opened and having a ring, a watertight packing, a washer, an elastic member, a wedge and an elastic ring sequentially inserted; The pipe joint structure is composed of a pipe which is coupled to both sides of the fitting by a one-touch type. In the pipe joint structure, a coating layer made of a PE material is formed on the outer circumferential surface of the fitting and the pipe, and an outer packing member is inserted at both ends of the coating layer of the fitting. And the gap between the fitting and the pipe is blocked to prevent corrosion during embedding.

According to the present invention, there is provided a connector comprising: a fitting of a metal material which is expanded in three directions and in which a ring, a watertight packing, a washer, an elastic member, a wedge and an elastic ring are sequentially inserted; The pipe joint structure is composed of a pipe which is coupled to both sides of the fitting by a one-touch type. In the pipe joint structure, a coating layer made of a PE material is formed on the outer circumferential surface of the fitting and the pipe, and an outer packing member is inserted at both ends of the coating layer of the fitting. And the gap between the fitting and the pipe is blocked to prevent corrosion during embedding.

According to the present invention, it is possible to form a coating layer of PE on the outer periphery of the joint where the pipe is bound in one-touch type on both sides or in three directions, and the outer packing member To block the exposed part of the fitting and to block the gap with the buried pipe to overcome the possibility of corrosion caused by the metal pipe and the fitting during the burial, thereby prolonging the life of the pipe and the fitting, / RTI >
