Abstract

PURPOSE: A water conveying pipe is provided to improve the strength against internal pressure and the temperature keeping characteristic by forming the water conveying pipe in a dual structure including a polyethylene resin pipe at an inner portion thereof and a stainless pipe at an outer portion thereof. CONSTITUTION: A water conveying pipe(1) has a dual structure. An inner pipe(2) thereof is made of polyethylene and an outer pipe(3) thereof is made of stainless steel. After fabricating the inner pipe(2), the outer pipe(3) is coated on the inner pipe(2). The water conveying pipe(1) is used for a heating pipe in a building or house. The water conveying pipe(1) is connected by means of a connection socket(4). The connection socket(4) includes a body screw section(6) and an outer connection pipe(5) to which a fastening nut(8) is coupled. A thin ring(7) is integrally formed at an inner portion of the outer connection pipe(5).

Description

Structure for a water feed pipe having the covering of stainless steel-piping}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a structure and a ducting device of a water pipe for providing a water pipe, a water pipe, a heating pipe, and the like, a means for connecting water, and a new pipe, in a novel configuration.

In particular, the water pipe for the purpose of the present invention is to provide a high-quality piping system suitable for the use of the heating pipe to be installed on the floor for the purpose of internal water pipe piping and heating of a general building.

Conventionally, the water pipe used for the above-mentioned purpose has been preceded by a pipe means of a synthetic pipe, a metal pipe such as a copper pipe, an aluminum pipe, or the like, using a PVC material, which is called an "Excel Pipe". It did not possess various desirable physical properties such as heat retention, heat dissipation effect and corrosion resistance.

For example, the former synthetic resin tube has good flexibility as a piping means and good economic efficiency in consideration of cost, but is weak in chemical resistance, pressure resistance and durability,

Copper and aluminum pipes, which are nonferrous metals, have low corrosion resistance, durability, and pressure resistance. Especially, when the pipe is connected to the socket, the sealing effect is poor due to poor adhesion effect with the socket. There was a problem.

The present invention is characterized in that the water pipe is suitable for various physical properties such as pressure resistance, durability, chemical resistance, heat retention, etc., in particular, because it has good adhesion to the connecting socket, which is a fitting means, and the piping is easy and the long term sealing effect is advantageous. .

The present invention is a pipe used for indoor water supply pipes and heating pipes of various buildings, the inside is a double pipe body in which a polystyrene (hereinafter abbreviated as "PE") resin pipe is embedded as a core pipe body and coated with a stainless pipe outside thereof. The present invention has been completed with the technical problem of the present invention by providing a water pipe that meets various required physical properties such as pressure resistance, heat insulation, adhesion to the connecting socket required by the water pipe.

1 is a perspective view showing the structure of the water pipe 1 and the fitting socket thereof showing a preferred embodiment of the present invention.

That is, the configuration of the water pipe 1 provided in the present invention is composed of a double pipe, the inner pipe 2 is composed of a PE pipe body, the outer pipe 3 is formed of a double pipe body consisting of a stainless (SUS) pipe.

The second step of the double pipe is constituted by a step of forming the inner pipe 2 made of PE pipe in advance and covering the outer pipe 3 made of stainless steel pipe on its outer surface.

The water pipe (1) is mainly used as a built-in water supply pipe and heating pipe of the building and the connecting means thereof is connected by the connecting socket (4) as shown in FIG.

The connecting socket 4 is composed of a main body screw pipe part 6 to which the constant connection capillary 9 is coupled to the rear, and an external connection pipe 5 to which the tightening nut 8 is coupled, and the external connection pipe 5. The inner side of the thin gripping ring 7 is integrally connected.

At the time of the fitting, the water pipe 1 is inserted from the tightening nut 8 side and pushed into the outer surface of the clamping ring 7 so as to be in contact with the inner side of the connecting socket 4, and then the tightening nut 8 is tightened. The inner inclined clamping portion of the tightening nut 8 presses the outer surface of the water inlet pipe 1, that is, the stainless outer pipe 3 inward, so that the inner tube 2 made of PE is formed on the outer side of the clamping ring 7. Strongly adhered by its flexibility and elasticity, the connection socket 4 and the water pipe 1 are welded in a very good sealing state.

Reference numeral 10 in the figure shows the packing.

The water pipe 1 of the present invention, which is connected by the above-described configuration and the welding device, is characterized by the configuration of a double pipe body whose outer side is composed of a stainless outer tube 3 and the inside is composed of an inner tube 2 of PE. The application effects are as follows.

① Outer pipe (3) is made of stainless steel, so it has good rigidity, good pressure resistance, durability, and corrosion resistance, and there is no risk of rust or corrosion during long-term use. Even if tightly adhered by), the inner diameter of the tube is not reduced or deformed, so the weld condition is extremely good and there is no fear of leakage.

② Since the inner pipe (2) is a PE pipe, in particular, the sealing effect of the connecting socket (4) and the clamping ring (7) of the connection pipe is good and the sealing state is not relaxed.

③ Since the inner pipe (2) is made of PE, there is no surface corrosion and no scale occurs when water or heating water is distributed, so the distribution of water can always be kept in a clean sanitary state.

④ When used as a heating tube, it has good thermal insulation and can maximize heating efficiency, so it can be widely used as a heating piping material.

Claims (1)

In constructing the water pipe (1) to be applied as the internal piping material of the building; The inner tube (2) of the water pipe (1) is composed of a tubular body made of a PE resin, the outer surface of the inner tube (2) is covered with an outer tube (3) made of stainless steel pipe, characterized in that composed of a double tube Pipelined water pipes.
