Winter - this is such a time of the year, which not only brings a memorable and joyful experience of the New Year or ski.Winter is a severe test, both for living beings and for all sorts of engineering systems that are created by man to improve their livelihoods.The tests relate directly to low temperature water supply system.The cold is such that freezing water pipes.Therefore, such knowledge as to defrost pipes in the winter and do not stay in this time without water, will be quite useful.

Need to defrost pipes
In case you have not made a timely warming of water pipes, it may happen a situation where water freezes in pipes.If you pay attention to the appearance of time with tap water to fo
the banal reason happening freezing water pipes: improper pipe laying technology (for the area does not include the depth of freezing or made pipe insulation), and the lack of indoor heating.Also, the reasons for the freezing of the system may be as follows: the tubes are transported very small amounts of water or tube operated at very low temperatures.
It should be borne in mind that the defrosting pipes that are laid in accessible places does not cause particular difficulties (for example, they only need to warm up using ordinary household dryer), but with defrost pipes at underground laying may have some difficulty.Pretty good, if the pipes were frozen in place input, as you can simply heat the walls.But often, the freezing point is a few meters from the building.
Question defrost pipes solved with the help of available tools that are available in each building: blowtorch, electric heater, hair dryer professional building (you can also use a hair dryer).But before you consider options for thawing water pipes, it is necessary to clarify a few useful tips.
defrosting process is quite simple, if the metal pipe.For this purpose we take an ordinary welding machine and carry out the connection to different ends of the pipe.This simple way to eliminate this problem for 3 - 4 hours.The longer the frozen section of pipe, the longer it lasts defrosting.However, currently used primarily in water supply networks PE pipes, which are made of high density polyethylene and withstand pressures up to 10 atmospheres.
They are not destroyed by freezing and not subject to corrosion processes.Polyethylene with properties not acting electrical conductor, and it is said that it is impossible to conduct defrosting using the welding machine.Remove with a steel rod, too fraught with ice jams can damage the pipe.
Traditional methods of defrosting pipes
Today a lot of ways to defrost, so not too difficult process of removing ice from the sewer or water pipes.
Outdoor defrosting pipe is a very important drawback - the need to open a trench in which the sewer is laid.Digging of frozen ground (and it is that is, if the ice formed in the pipe), the occupation, it is clear that not one of the most enjoyable.Still, if the tube size is not particularly large, this method, it may be worthwhile to apply.
Once you have opened the trench, it is necessary to look at the material from which the pipe is made.There is a difference in how thawed plastic or metal pipes.In the first case you need to use these electric heaters so that the temperature was not very high - up to 100-110 degrees.At the same time as it makes sense to cover excavated additional land a decent layer of insulation in the process of thawing, so the reverse side of the machine will not heat the outside and warm as the pipe faster.
for metal pipes is applicable way to use open flame through equipment such as gas burners, blowtorches, firewood, and any sources of ignition with a long burning time.From these influences can simply melted plastic.
defrost water drain pipes, compared with water pipes has certain nuances.On one side of such large diameter pipe offers considerable advantages for the internal heating.On the other hand, these pipes provide quite a large amount of accumulated ice and frozen ground, and therefore a larger contact area, resulting in increased heat transfer heaters, both external and internal.
Before plastic pipes unfreeze the inside, you need to make is not very sophisticated device: on a board with rounded edges to fix the U-shaped heater.At the same time it takes to bend advocated cutting edge boards, other parts of the heating element must not protrude beyond it, to no contact with the walls of the tube heater.
Because its size and distance to the traffic jams are known, for defrosting the plastic pipes must also be attached to the heating element contacts the appropriate length of the wire and attach the plank to the very small piece of metal-plastic pipes, which will serve as a pusher.
the receiver side is thrust drains the whole structure, because it is a bias sewage made in this direction, from top to nowhere will drain melt water.In this heater is switched network only after the tube is placed inside, and at every movement as stoppers are melted respectively disconnected.
apparatus for metal pipes
most effective means of removing ice from the water supply system is an industrial unit to defrost pipes.However, such a device is intended only for metal pipes, plastic pipes on the technique does not apply.The operating principle of the machine is quite simple and straightforward.On the edge of the desired portion of the pipe that you want to unfreeze, attach the terminals, then a current is applied.Thereafter, the tube is heated and begins to thaw frozen place.
When using the machine for thawing metal pipes should review the following data: pipe up to 23 meters and a diameter of up to 6 centimeters thawed to 60 minutes.A larger diameter of the pipe must be installed on the terminal shorter, especially in the area of different frames and measuring instruments.When do you defrost water or sewer pipes need to be present in the system water pressure.
unconventional way defrost pipes
In addition to traditional methods of thawing pipes, can you offer for polyethylene pipes are three ways to defrost, which are "know-how" of our craftsmen.Regardless of some eccentricity, they still work.The only disadvantage them is that they are suitable only for pipes that have a small diameter.
When using this method, be aware that an ice plug will not allow to get into hot water if it just poured.So you need to find a way to feed in the frozen zone of hot water.Thaw tube can, using the pipe or hose with a smaller diameter.For example, if you want to unfreeze water pipes with a diameter of 25 or 30 millimeters, and the frozen segment is straight, it is more efficient to use plastic pipes with a diameter of 16 millimeters.
to start the composition pipe straighten, and then pushed her into a frozen pipe, until it touches the ice.After this, the tube is fed to the place of the hot water from freezing.Thawed water will be in the gap between the plastic pipe and water pipe to pour.If you have a limited supply of water, it can be thawed water used in the second round, that is, to heat it, and again directed to the place of freezing.
ice plug at the same time will melt and you can continue to manually defrost pipes and metal-plastic tube to push a little further.But if the section of pipe that is frozen and has twists and turns, use in this case a rigid composition pipe fail.But you can take the hard hose.
should be noted that an ordinary garden hose is not suitable for this purpose, it simply from the hot water and soften it can not be pushed.In such a situation were effective hoses for connecting a gas cylinder and oxygen lines.These hoses quite stiff, but still they can push on the input is not more than 15 meters.In addition, these hoses are heavy and trumpet their push followed with great effort.
And now is figure out how to unfreeze the pipe if there was accumulation of ice tens of meters from your doorstep, and the pipeline itself has twists and turns.Still, there is a cost-effective and efficient way: for such purposes will need a set of building gidrourovnya, mugs douches (banal enema) and hardened steel wire.Such a set value is small, and many households have all its components.
First you need to align the wire and tube gidrourovnya, and then fasten with tape to gidrourovnya end of the wire.In order to ensure that at the end of wire greater hardness, it is necessary to make a loop.The wire itself does not have to hang around and in front of wire one centimeter should act gidrourovnya end of the tube.The other end of gidrourovnya then be connected to the mug Esmarch, and then push the wire all the way to the tube in running water.
Due to the fact that the tube gidrourovnya has a small diameter and low weight, it is fairly easy moving through the pipeline, thus overcoming all the turns is pretty simple.Then pour hot water, making the "enema" frozen water supply.Under the water pipe to collect the thawed water is necessary to substitute the capacity, because as hot water is poured, the same will pour cold.
Next pushes the wire with the tube gidrourovnya gradually as the ice will melt.This method of defrost pipes are very long, that is, an hour to defrost can only be up to one meter of the pipeline.So during working hours can be thawed ice 5-7 meters of the pipe.
Consider the following scenario when you have a frozen plastic water pipe length of 50 meters, a diameter of 20 millimeters and a depth of laying - up to 80 centimeters.It should be noted that such a depth for lack of water pipeline, so water and frozen.Another distinctive ability - that is water under the roadway.In this case, the utility usually advised to wait until the thaw comes, but still there is a way that you can do without it.
You will need the following equipment: fork sockets, two-wire copper (thickness and length of section select the diameter and length of the frozen water pipe), hose and compressor for pumping the thawed water.For example, for a tube diameter of 20 millimeters can take 2.5-3 mm wire and automotive fuel hose diameter of 8 millimeters, as well as conventional compressor car (can, in extreme cases, use a pump).
cautioned that using this method of self-defrosting pipes need to be especially careful, because the work is done with the use of high voltage.And now all you need to prepare to thaw pipes.It is necessary to remove a small section of the wire outer insulation, divide it into two wires, one of them be stripped, and the remaining wire insulation gently bend in the opposite direction along the aqueduct.It is necessary to ensure that the insulation is not damaged.
Next almost near the bend wire should make 3-5 turns of bare wire (as closely as possible to each other) and its remaining end of the cut.After that, made from coils need to withdraw 2-3 mm, then - the second wire and bare wire around her entwine just as well.You should not touch the first and second turns of wire.
And on the other end of the wire connects "unit" and fork (such device is called "bulbulyator").If it is placed in the water and make a connection to the mains, when the passage of current through the water occurs corresponding reaction, which takes place a large heat release.Such a device is ideal in this case, because only water is heated, and wire themselves remain cold, ie plastic tubes propalivayutsya even accidentally.
This device is assembled sure to check.For this purpose it is recommended to send in a jar with water and connect the device to the power supply.If you feel a slight buzz, and depart from the bubbles of contacts, respectively, the unit operates.We remind you once again that the device is working, when in contact with water may occur electric shock.
continue on their own to defrost tube.The wire must be push gently into the pipe so that when he does not bend.It is therefore necessary to take heavy gauge wire.When abuts the ice plug wire must include "bulbulyator" and a minute or two wait.Then you should try to push the wire on because the ice began to melt.
When a meter pipes thawed, melted water is necessary to blow by the compressor, it is necessary to reduce the amount of water and heated to over water does not freeze on the already thawed areas.If you have special equipment, it is desirable to weld the pipe tap.When water flows through a pipe from it not pull the wire and close the valve, so not going to happen flooding the place where the procedure is carried out defrosting.
How to prevent freezing pipes
you already understand how to cope with ice-water pipes.But you can prevent this if you try.To avoid freezing plastic pipes, remember:
- The conduit should be at a depth that exceeds the level of soil freezing in your area.Sewer and water pipes are laid at a depth of desirable not less than 120-140 centimeters.
- no need to lay sewer and water pipes near the reinforced concrete structures (beams, supports, gratings, the foundation) because of the fact that the thermal conductivity much more concrete thermal conductivity of soil, that is, increases the risk of soil freezing on the part of reinforced concrete structures.It is necessary in this case to produce insulation pipes (for example, placed between the concrete structures and pipe plate of a special extruded polystyrene).
- If finances permit, near the pipeline should pave the heating cable.Already utilized in the present, the production of self-regulating heating cables, which are included only when needed.
- places where pipes pass through the walls of buildings and structures, it is desirable to warm mineral cotton, foam and glass wool to avoid direct contact with the walls of the structure of the walls of the pipe.
- When constructing water pipe near her house is better to use a pipe that has a diameter of at least 50 millimeters, because the smaller diameter tubes are subject to a freeze.
- making a choice between a variety of water plastic pipes need to know that polypropylene pipes may burst after 2-3 defrosts and polyethylene pipes are resistant process repeated thawing and freezing.
