Conventionally, when cleaning piping as described above, after installing the processed piping, the piping is dismantled from the site for cleaning, carried outside the premises, and washed - degreased - washed with water - pickled - washed with water - outside the premises. So-called off-line processing, in which neutralization, rust prevention, and other treatments are carried out in a liquid tank, involves transporting cleaned piping to the site and installing it.
しかし、上記の如き、いわゆる、オフラインに
よる配管洗浄方式では、洗浄に要する時間とコス
トが多大となる問題がある。 However, in the so-called off-line pipe cleaning method as described above, there is a problem in that the time and cost required for cleaning are large.

However, in the case of the above-mentioned method of cleaning piping assembled on-site in its original position, unlike liquid tank treatment such as off-line treatment, the inner surface of the piping is cleaned by flowing treatment liquid into the piping. Because of this, some parts have complicated bends, etc., making it difficult for the processing liquid to circulate sufficiently in some places. There are problems such as the need for a pump.

In order to achieve the above-mentioned purpose, the present invention consists of a processing liquid supply pipe that can be connected to one end of the piping assembled on site, and a processing liquid discharge pipe that can be connected to the other end of the piping. A pulsation generator is installed in the middle of one of the pipes to give pulsation to the processing liquid, and the remaining chips cut out during the processing of the pipe are put in as samples for processing. The remaining chips are treated with the liquid, and a transparent container is interposed so that the remaining chips inside can be visually observed from the outside.

時間を短縮させることができる。 When cleaning the piping 1, chemical cleaning is sequentially performed for each process such as degreasing, pickling, neutralization and anti-corrosion, but the treatment liquid 10 necessary for cleaning in each of these treatment processes is supplied from the treatment liquid tank 9. A part of the liquid is pumped by the pump 12, stored in the liquid chamber 19 of the accumulator 16, and the rest is flowed into the pipe 1 via the header 4, the supply branch pipe 3, and the valve 11. Processing liquid 10 flowing inside pipe 1
Cleaning is performed by the flow rate and the impact of the processing liquid 10 hitting the inner surface of the pipe 1. If the piping 1 is long and continuous, there will be parts where the processing liquid 10 is difficult to circulate, but the volume of the liquid chamber 19 of the accumulator 16 is
By changing the supply of pressurized air in the gas chamber 18 by turning on and off with the solenoid valve 20, the processing liquid can be made to pulsate, so the pulsation allows the processing liquid to reach areas where it would otherwise be difficult for the processing liquid to reach. The cleaning process can be further accelerated as the water can be rotated more efficiently. Thereby, the cleaning effect of the entire piping 1 can be enhanced, and the time required for cleaning the entire piping can be shortened.

理不良や過処理を防止することができる。 The cleaning status of the piping 1 is that the remaining chips of the piping inserted into the transparent container 13 interposed in the middle of each discharge side branch pipe 6 are being simultaneously treated with the treatment liquid, so the cleaning status of the remaining chips is as follows. A transparent container 1
3 can be easily and accurately grasped by visually checking from the outside, and it is possible to prevent processing defects and over-processing in each processing step.

As described above, according to the piping cleaning device of the present invention, the inner surface of the processed and assembled piping can be cleaned.
In so-called on-line processing, which involves chemical cleaning treatments such as degreasing, pickling, and neutralization to prevent rust, the pipes on the processing liquid supply side and the processing liquid discharge side can be connected in series to the assembled piping. A pulsation generator is installed in the middle of one of the pipes to give pulsation to the processing liquid flowing into the pipe, and
The remaining chips cut out during the processing of the piping are placed as samples, and the remaining chips are treated with the processing liquid, and a transparent container is interposed so that the remaining chips inside can be visually observed from the outside. Because of the structure, the pulsation allows the processing liquid to circulate better even in parts of the assembled piping where it is particularly difficult for the processing liquid to circulate, further promoting the cleaning of these parts and improving the overall processing effect. The cleaning process time can be shortened without using a conventional large-capacity pump, and the inside of the pipe is cleaned using a transparent container that is simultaneously cleaned with the processing liquid used to treat the inside of the pipe. The cleaning process status of the remaining chips as samples inside the pipe can be visually checked from outside the transparent container, so the cleaning process can be checked from the outside without having to take each sample out of the pipe and check it. By visually checking the processing status of the remaining chips in the transparent container, it is possible to immediately and accurately grasp the processing status of the piping, and it is possible to prevent processing defects and overprocessing in each processing process. The pulsation of the liquid accelerates the processing inside the pipes, resulting in efficient cleaning. By looking at the processing status of the remaining chips in the transparent container, you can accurately understand the processing status of the pipes and prevent over-processing. It can produce excellent effects.
