Description

Reducing branch pipe for piping {A REDUCING BRANCH PIPE FOR PIPE ARRANGEMENT}

The present invention relates to a piping member, in particular, TEE (TEE), pipe short pipe and reducer is formed as a single body to significantly improve the productivity to reduce the manufacturing cost, prevent corrosion to prevent leakage and maintain the pipe in the future The present invention relates to a reducing branch that facilitates management, maximizes pipe life, and is formed through a hot forming process to prevent cracks and stresses and significantly improve quality characteristics.

In general, a fire sprinkler is installed on each floor of a building such as a building or a multi-family house to detect fires around the ceiling and automatically spray high pressure water to extinguish the fire early.

To this end, the piping line for supplying the fire water is branched step by step from the main pipe for supplying the extinguishing water from the outside, and a sprinkler is installed in the last branch pipe, and as shown in FIG. 1, the branch pipe from the main pipe 2 is shown. (3) is a branch joint, and the branch (TEE) is formed in the branch pipe (3) again and the branch pipe is branched to the left and right to branch, and the reducer that the inner diameter is narrowed to strengthen the hydraulic pressure and flow rate to the left and right of the tee The reducing branch pipes 10 and 100 for the pipe are formed, and the branch pipe 4 to which the sprinkler 5 is installed is connected to the reducing branch pipes 10 and 100.

In the prior art 100 of the reducing branch pipe for such a pipe, as shown in FIG. 2, the pipe end pipe 130 is welded and welded on both sides of the tie 110, and the shaft diameter is formed in the pipe end pipe 130, respectively. The reducer 150 is configured by welding again.

The prior art piping reducing branch pipe 100 is provided with two pipe end pipes 130 and two reducers 150 in the tie 110, so that the total number of parts reaches five, the accuracy is required to maintain confidentiality There are problems that the welding joint part 170 reaches four places, and the manpower and time are enormously required for material cost and its manufacture, which significantly lowers the productivity.

In addition, a leak occurs due to corrosion generated in the weld joint 170 with the pipe end pipe 130, and thus, there is a problem in that maintenance work such as maintenance work is difficult.

On the other hand, there is a problem that the loss of the material occurs as the cutting work for forming the pipe short pipe 130 is involved.

The present invention has been devised to solve the above problems,

The object of the present invention is that the TEE, pipe pipe and reducer are formed in one body to dramatically improve productivity and reduce manufacturing costs, and to prevent leakage to prevent leakage and to easily maintain pipes in the future. To provide a piping reducing branch pipe for maximizing the pipe life.

Another object of the present invention is to provide a reducing branch for piping that is formed through a hot forming process to prevent cracks and stress generation to significantly improve the quality characteristics.

Reducing branch pipe for piping according to the present invention to achieve the above object,

In the piping member, the inner diameter is reduced in the left and right both sides of the TEE portion, characterized in that the reducing portion for connecting the branch pipe is formed integrally.

The left and right both directions of the TEE part may be extended to form an extension part between the TEE part and the reducing part.

The reducing portion may be threaded on an inner circumferential surface to be screwed with the branch pipe, or a predetermined welding bevel angle may be formed at the tip to be welded with the branch pipe, or a step may be formed to be socket welded.

The TEE part and the reducing part may be formed through a hot forming process.

Hereinafter, an embodiment of a reducing branch for piping of the present invention will be described in more detail with reference to the accompanying drawings.

3 is a cross-sectional view showing the configuration of the reducing branch pipe for an embodiment of the present invention.

The reducing branch pipe 10 for piping according to an embodiment of the present invention, as shown in Figure 3, in the piping member, the reducing portion whose inner diameter is reduced in the left and right directions of the TEE (11) ( 15) is integrally formed.

The left and right both directions of the TEE part 11 may be extended to form an extension part 13 between the reducing part 15 and the reducing part 15.

The reducing unit 15 is preferably formed with a screw thread (15a) on the inner peripheral surface to be screwed with the branch pipe (4).

As the reducing part 15 is partially omitted in FIG. 4, a predetermined welding bevel angle θ is formed at the front end of the sprinkler to be taste-welded with the branch pipe 4 where the sprinkler is to be mounted (a pruning) Joe), step 15b may be formed to connect the branch pipe 4 and the socket weld (see also b).

The reducing branch pipe 10 for piping according to the present invention is preferably formed of carbon steel.

As such, the present invention in which the TEE part 11, the reducing part 15, and the extension part 13 are integrally formed is formed through a hot forming process, thereby forming the TEE part 11 and the reducing part ( Even if 15) is integrally formed, it is possible to manufacture a product having excellent quality characteristics such that cracks and stress do not occur.

As such, forming the TEE part 11 and the reducing part 15 integrally may be performed by cold working, but in this case, an expensive heat treatment process is required because corrosion occurs due to cracking and stress generation. There is a drawback required.

The reducing branch pipe (10) for piping according to the present invention having such a configuration is formed by a body (TEE) portion 11 and the reducing portion 15 is formed in one body communicated with the main pipe side is conventionally Many of the components and welded joints involved in the technology are eliminated, which significantly improves productivity.

In addition, the pipe short pipe welded joint is excluded to prevent the occurrence of corrosion and the resulting leakage, minimize the repair work, etc. to reduce the maintenance cost of the pipe and maximize the life of the pipe.

The reducing branch pipe (1) for piping of the present invention can be applied in various ways to form a standard step by step.

The present invention is not limited to the above-described embodiments and drawings because various substitutions, modifications, and changes are possible to those skilled in the art without departing from the technical spirit of the present invention. .

As described in detail above, the reducing branch pipe for piping according to the present invention,

TEE, pipe short pipe and reducer are formed in one body to dramatically increase productivity and reduce manufacturing cost. Corrosion prevention prevents leakage and facilitates maintenance of pipes in the future and maximizes pipe life. It is a technology that has advantages.

In addition, since the reducing pipe is formed through a hot forming process, cracks and stress are prevented to significantly improve quality characteristics.
