A variety of bending pipe leakage leakage causes performance

Views: 3     Author: pqwt     Publish Time: 2022-08-30      Origin: PQWT

Bend pipe has a very strong performance, has the advantages of bending, but also has the straight pipe does not have the performance, so it has become a business construction management unit commonly used through the pipeline, must avoid pipeline leaks. Pipeline leakage will also affect the construction, so it must be eliminated leakage, so how do you need to operate specifically? Let's take a look at it!

1. hot fusion connection bending pipe breakage range is very small, electrofusion set or improved saddle electrofusion tube repair method cut off the broken part, connect the electrofusion set or improved saddle electrofusion tube, the connection should pay attention to strictly in accordance with the standard in accordance with, prevent damage to the electrofusion set.

2. When the hot fusion composite tube connection is damaged extensively, the damaged section of the tube needs to be removed, and then connected using intact exchange tubes, welded joint sleeves or flanges, and if it is irreversibly damaged, it must be replaced in time.

3. In case of leakage at the connection interface, please cut off the bent piping and reconnect the piping and piping components according to the requirements of engineering construction technology, which is very important for the connection of bent piping, otherwise it is impossible to repair the leaking piping.

4. Remove the broken pipe section, replace the pipe, and connect to the movable double pipe hoop or collar.

5. When the nominal outer diameter of the small piping is broken, use the device for repair to connect, you can remove the broken section of the bent pipe and replace it with a new piping.

The connection operation is not sufficient and the construction method is not excluded. There are many reasons for leakage of the bent pipe, so it is necessary to connect the fracture section well, and it is also possible to cut off the broken component part again and re-establish the connection to prevent leakage.

Regardless of the shape of the bent pipe, in order to maintain good performance over time, please extend the life while paying attention to maintenance.

Using the pqwt pipe leak detector can pinpoint the point of pipe leakage.

pipe leak detector

In general, the basic detection method is, connect the pipe leak detector host, headphones, sensors. Turn on the pipe leak detector switch, wear headphones, the sensor placed on the road above the pipe line, placed step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks. Therefore, we use the instrument, a single point to listen to the leak signal is not meaningful, to multi-point repeatedly compared, compared with the sound vibration of the larger place is the leak, of course, we have to consider many other additional factors, such as the direction of the leak breakage mouth, because the pipe is round, if the side of the leak, may be larger points instead in the side of the road above the pipe, rather than being the pipe Above the road, so the location of the pipeline should be known, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact, the detection should take these into account.

Hunan Puqi Geological Exploration Equipment Research Institute is a professional institution engaged in pipeline leak detection equipment and urban pipeline loss reduction research. Mainly committed to the underground pressure pipeline leak detector application technology research and scientific research and undertake the "National Thirteenth Five-Year Water Special Research Project". Our institute insists on the strategic goal of "developing the institute with science and technology and strengthening the institute with talents" and implements the open-ended policy of running the institute. advantages.
