What to do if buried pipe leaks and how to remedy it

If the buried pipe leaks, it makes people feel very annoying. One is to affect the residents' household water, and the other is to bring all kinds of troubles due to the leakage causing the leaking area to be wet with water. Once a buried pipe leak is found, you should immediately use the correct method to accurately detect the location of the leak, and to promptly repair the good or replace the new pipe, and to take the initiative to compensate others for their losses if it causes some damage to their lives. So, how should I find buried pipe leaks? The following is the experience provided by the editor, I hope it will be helpful to you.

What are the methods of leak detection for buried pipe leaks.

First, you can use pqwt pipe leak detector, pipe leak detection, 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 pipeline, 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 pipeline leak detector, a single point in the leak signal is not meaningful, to repeatedly compare multiple points, compare 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, the larger point may instead be on the side of the road above the pipe, rather than The road above the pipeline, so the location of the pipeline to know, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact on the detection of these to take into account.

Buried pipe leakage how to do: 1.

1. Large area leaks

First, if the underground pipeline leakage is large, it is recommended to cut off the leaky parts and re-weld the same diameter or thickness of the same steel plate. But before welding, . After welding, rust prevention should be carried out respectively. Anti-corrosion treatment. If the iron pipe has cracks in the circumferential direction, steel pipe casing must be added. If the pipe is cracked longitudinally, the cracked area can be cut off and put down the casing again.

2. Patch welding

Next, when the pipe is patched, the water valve should be closed, then the leaking surface should be wiped clean, a hole should be drilled on both sides of the crack to supplement the welding bevel, and then corrosion treatment should be carried out. In addition, if it is an iron pipe, it needs to be welded with iron bars.

Finally, if the water pipe flange is damaged leading to a leak, when replacing the rubber gasket, care should be taken that the bolts must be aligned with the holes before they can be tightened. If the foundation is sinking, it is recommended to add support posts to the pipe. In addition, if the bearing port of the water pipe leaks, the surface must be cleaned, compacted with linseed oil, and then sealed with asbestos cement
