During execution of engineering works, experts frequently make mistakes due to water which may freeze when filing. As a result, the system can be damaged, and in a serious congestion ice pipe rupture occurs. Therefore, residents of the private sector is concerned, both independently unfreeze polypropylene pipes and prevent the occurrence of an emergency.
Why obrazuetmy ice in the pipeline
There are several reasons for which the ice is formed of polypropylene pipes:
- There was a sharp temperature gradient, causing the marker has reached a critical point. Typically, the freeze deeper layer of the ground.
- When laying a pipeline dosed with a small depth.
- If the owners for a long time away from home, the room was not heated, water retention freezes. Therefore it is recommended to carry out dehydration before leaving.
- In the case freeze drain, it may indicate a lack of inclination or with a minimum of waste.
Since the pipes are made of polypropylene plastic material, the risk of cracks is minimized. Often, it is able to stretch and take a new volume. But it is not recommended to abuse this feature.
What to do when defrosting open the pipeline
When deciding how to warm the portion of polypropylene pipes, the task becomes much easier if you have direct access to it. Then you can use an external heating. It is important to take into consideration that, for heating the outside of the polypropylene tubes, metal or polyethylene, are allowed to use a heating cable type electric heating pad. If the heating is formed from a metal structure, it is permissible to use an open flame. Typically, soldering is necessary, the burner for gas or can be made common torch.
Before you can solve a problem with warming, do the following:
- Know which portion of the structure is frozen by incorporating the nearest unit for draining water, had time to thaw.
- Before starting the defrost compulsorily switched off the heating boiler, pressure drop of the unit, as well as run a special pump loop, open drain water from a special contour, by which the heating.
- Enable to prepare a heating element or a burner for gas in dependence on the selected method. Warming is performed at a safe distance, starting from the area where the clan has a special drain and move to the standpipe.
- If you plan to use electric heating elements (burner or cable), they must be pre-wrapped around the frozen portion and connected to the power supply. The best option for winding becomes an old blanket or bedspread.
- After some minutes of the crane can go a little trickle of water. This is the first indication of polypropylene pipes for heating using the correct tool and ice gradually thawed. With increasing pressure, heaters can be turned off.
It is important to note that if the pipe of the cold in the apartment, you can simply turn on the hot water. Sufficiently warm kettle and to pour the outside of the tube.
Pre necessary to wind a cloth, avoiding direct contact. At home, in the alternative may be to use:
- an electric heater,
- industrial dryer,
- lamp with a deflector.
Methods defrost polypropylene tubes
There are several effective ways to help cope with the task without causing harm sewage:
- If there is an open access, the simplest way to start the wind pipe some material and used for watering the cool water, you can gradually increase the temperature. In the final step allowed the use of hot water. The main thing - do not forget to open the valve to maintain a constant flow. Alternatively, it is advisable to use a special dryer for industry or construction works. However, the need to control the temperature regime to avoid defrosted water plastic parts.
- More difficult task when the pipe is in the ground and it is not direct access. You can use the high pressure of hot water. This would require to disassemble the tap water pipe and a small portion to allow access of water supply. Further it is necessary to choose the diameter of the hose pipe. Length should be enough to ice jams. Hot water is supplied by a pump. It is also recommended to take care of special containers to collect the thawed water. It will come back.
Attention, alternatively, may be used pairs. However, the temperature must be within the range of 100-150 degrees. Relevant to external networks.
- If there is a hydraulic device, the task becomes much easier. Typically, the local water utility also offers its lease. But here you need to show some consideration. In the event of a sharp drop in temperature, the polypropylene material becomes brittle. It is best to provide heating in the range of + 10-20 degrees.
- The undeniable fact is the active effect of salt on the ice. Pre water must be pumped out and fill it by brine. The process takes more time, but the rapid build-up of ice will be suspended. Importantly, the presence of salt water will solidify more slowly.
To perform the task possible, but it is worth a lot of patience, because the process takes a lot of time. Must act slowly to avoid deformation of the tubes.
simple instructions
Self-defrosting pipes fit another way. It should be considered in more detail:
- Prepare from ordinary copper wire and a plug adapted to the socket.
- An upper insulating layer is removed.
- One core is laid bare, and the second - is bent in the opposite direction, that stretch it along the wire.
- From conductor is twisted a few turns (ideally at least three), by means of pliers eliminate residues.
- Indent in a couple of mm and tighten the rest of mine.
Advice: The coils must not come into contact with each other in order to avoid closure.
- Connecting the device and starting its operation.
- Once the ice melted pair mm, it is necessary to connect the pump and to pump out the water formed. You can also use a special compressor. Otherwise, it may happen re-icing.
Such a device is actually used for polypropylene because the melting eliminate. Furthermore, it will be made only hot water and ice. Compressor relevant if the pipe length is more than 30 meters. Pre can conduct a number of tests, using an ordinary bowl. From the end should be heard humming sound.
