Installation of a polypropylene pipeline is so simple that you can easily carry it out even in between watching your favorite TV shows or series. The main thing is to stick to some general rules and understand the basic principles of joining plastic pipes. I will tell you all this from my own experience.

Installation work

Starting to work with polypropylene pipes, I first of all remembered their main qualities:

The low price allowed me without any abuse of the family budget purchase all the necessary plastic products, including connection fittings, with some margin. After all, even having the appropriate experience, no one is immune from making mistakes, and it is better if unsuccessful operation have replacement parts at hand, and not run after them to the store, leaving an unfinished pipeline and an unfinished series;

A simple connection instruction including "hot" and "cold" methods. But simplicity does not preclude the need for the presence of a special tool for each of the options. Next, I will describe in detail both of them, since I used both soldering and compression fittings in different areas. It is better for you to make a choice in advance in order to take care of the availability of appropriate equipment. You can do it right after reading the article;
No corrosive processes. The plastic surface is not subject to either internal corrosion, which can be provoked by the transported liquid, or external, which usually appears after the pipeline is laid in the ground. Thus, when laying an underground water supply, I knew that it would last for decades, but only taking into account the quality and absolute connections.

If you plan to use poly propylene pipes for the installation of a heating system, I recommend purchasing reinforced samples that can withstand high temperatures, which will eliminate the risk of an emergency.

Based on the foregoing, I purchased materials with a margin, took out the right tools and prepared to make quality connections that can be left unattended for years to come.

hot method

Where I planned to lower the water supply line underground, I had no doubts about the choice of the connection method: only soldering. The melting point of propylene is only 260 degrees Celsius, and after solidification are formed fully sealed seams. In addition, the process itself is quite fast. The impossibility of dismantling me in this case did not bother me at all.

When laying pipelines indoors, welding is also excellent. The only exceptions can be those areas where disassembly of pipes is required, or a situation in which it is not at all possible to get a pipe soldering iron.

If you have a one-time installation planned, then not cheap welding machine for plastic pipes it is not necessary to purchase, it would be more rational to rent it.

Before connecting polypropylene pipes using the “hot” method, in addition to the “iron”, I also prepared the following tools:

Now I will describe to you in detail how polypropylene pipes are connected, you really will have time to install small sections during the period of scrolling commercials on TV:

If this is your first time trying to solder plastic pipes, then I recommend that you first practice on a couple of products that will not be included in the system being installed.
So you "fill your hand" and can avoid typical mistakes when performing "clean" work.

Preparation:

I took out a soldering iron from a suitcase where he was, and placed it on a level and stable oak table. You can put the device on the floor or on the asphalt, the main thing is that it has a reliable position, because you have to deal with high temperatures;

Then inserted nozzles corresponding to the diameters of the elements to be soldered. At the same time, a product is installed under the pipe in the form of a kind of “bowl”, which wraps around its edge with outside, and under the tubular element that enters it and performs melting from the inside;

Turned on the device. If your device has a power regulator, then set it to 260-270 degrees Celsius. If this is not the case, then the unit will automatically heat up to the specified temperature;

Markup. Here I have already moved on to work with the pipes themselves. With a tape measure and a pencil marked out the necessary segments for the formation of the pipeline. In addition, measured the depth heating elements and, adding a couple of millimeters, applied it to the soldering points. This can be done after cutting products. This technique will help you control the immersion of the edge of the segment into the nozzle, since excessive melting can lead to the formation of a bulge in the seam that prevents the passage of liquid;

Cutting. The main thing here is to observe a right angle. Thanks to some experience, I have no problems with this, that is, evenly brought the scissors to the line and made a clear cut with one smooth strong movement. Try also, without excitement, with the necessary efforts to complete the cutting. Otherwise, if you make oblique cuts, you will have to level them with a hacksaw or knife. It is also worth noting that when using reinforced pipes, you must first remove the upper layer plastic and foil laid under it;

Heat. At this stage I I put the prepared coupling on the mandrel, and inserted the pipe section with some delay into the nozzle-sleeve. Why belatedly? Because the walls of the connecting element are thicker, and, accordingly, they will melt longer, that is, the head start will not interfere with them. Keep the products in this position should be guided by the following table:

Docking. After the above time has passed, I removed both fragments with melted edges from the welder and connected, again, strictly at a right angle, after which he held the time indicated in the following table:

Cross section, cm	Connection time, s	Cooling time, s
2	4	2
2,5	4	2
3,2	6	4
4	6	4
5	6	4
6,3	8	6
7,5	10	8
9	11	8
11	12	8

In no case do not turn the connected products at the time of solidification, as this may provoke a violation of the tightness of the seam.

Control. I let water through the finished pipeline and checked all joints for leaks. If you suddenly find one in yourself, then cut out the problem area and weld a new segment in its place.

cold method

Compression fittings allow you to connect polypropylene pipes without soldering. All you need besides the connectors themselves is crimp key, which, as a rule, is sold with them.

The very process of connecting pipes in a “cold” way, I performed as follows, when I didn’t have an “iron” at hand, and it was necessary to restore the damaged section of the water supply urgently:

Measured and cut off the desired pipe fragment;

Calibrated hole. It is very important that its cross section ideally matches the diameter of the fitting tail;

Put on the edge of the pipe ferrule;

Then I inserted the fitting itself inside;

Crimped the clutch with a special key, securely fixing it on the pipe;

I checked the coupling for the presence of characteristic recesses, indicating a quality connection.

The described method also solves well the problem of how to connect a metal pipe to a polypropylene one. To do this, simply select the appropriate compression fitting, in which one of the ends is equipped with a metal thread of the desired pitch and diameter.

If you have a question: "How to connect a HDPE pipe with polypropylene?" Then again, you can turn to compression fittings, since welding here, most likely, will not cope due to the significant difference in the melting temperatures of these materials. At least I wouldn't risk it.

And a bit of fly in the ointment: despite some versatility of the “cold” connection method, it takes much more time to implement. So, if you have to install a long pipeline, then during the time of advertising on TV you may not have time to cope with the task.

Conclusion

A little practice and following the above recommendations will allow you to lay water supply lines from polypropylene pipes, practically without looking up from watching your favorite TV shows and TV programs. The main thing is to be careful and accurate, since a mistake made will take much more time to correct it than timely control of the work being done.

Pipelines made of polypropylene, with their high-quality assembly, can last up to half a century without repair. The popularity of plastic communications in construction individual houses explained, among other things, by the fact that the installation polypropylene pipelines available for independent execution.

The choice of a method for connecting plastic pipes depends on the availability of a special tool, the nature of the materials being joined, and the purpose of communications.

All methods of installing polypropylene pipes can be divided into two large categories. One involves welding materials by heating an organic polymer to a melting temperature. The second includes all "cold" methods of connection, with the exception of cold welding.

Welded joints are called one-piece. Diffusion processes are involved here. Homogeneous polymers are mixed at the molecular level, forming a monolith. This docking is the most durable, but requires a special tool or glue (with cold welding). The second disadvantage is the impossibility of temporary dismantling of communications without destroying part of the structure.
Detachable (threaded) connections are made using special fittings. They are used when joining thin-walled pipes of small diameter, when making structures from different materials, joining polypropylene with polyethylene, with metal elements.

Diffusion welding

There are butt welding (pipe to pipe) and with the use of additional fittings (coupling). These are technologies based on the melting of polypropylene, which differ in the nuances of the work.

Diffusion sleeve welding is carried out on polypropylene pipes with a diameter of 16 to 40 mm.

Here the fitting serves to supply additional amount polypropylene to make the connection secure.

For thicker-walled materials, butt welding is carried out, connecting the pipe parts directly, without the use of additional parts. Manufacturers polypropylene materials offer fittings entirely from polymer materials, combined, with the transition to a thread for metal elements.

The fitting configuration is selected based on the characteristics of the pipeline. Manufacturers offer the following types of connecting elements:

corners, tees, couplings;
fittings for connecting elements of one diameter, with a transition to another diameter;
fully polymer or polymer-metal combinations;
with internal, external thread.

In apartments and private houses you can often see plastic pipes. The demand for such products in the last decade is justified by their low price, long service life and the fundamental impossibility of rusting.

You can connect plastic pipes to each other not only with a soldering iron, but also alternative methods- using flanges, fittings, couplings or by gluing.

Connecting plastic pipes without soldering will not require large financial costs. And you won’t have to get expensive soldering equipment somewhere (obviously, not everyone has it) either.

We have to admit that the soldering process itself seems very complicated to some. A person must be able to properly handle a soldering iron, set the desired pressure and temperature, and select solder. In general, in order to solder pipes with high quality, you really need to know a lot of nuances.

There is also such an option as soldering polypropylene pipes without a soldering iron. For this, solder paste is simply taken (this is already sold in ready-made a mixture of flux, solder powder and lubricant) is applied to the joint and heated. Moreover, instead of a soldering iron, it is proposed to use gas burner or a lighter. But this method may also cause rejection for some, since here you have to deal with open fire.

Imagine a force majeure situation: there was a breakthrough plastic plumbing. It can take a long time to restore its tightness by soldering. And the restoration of the tightness of pipes connected without soldering can be carried out much faster - this is a really important advantage.

Fitting connection

To connect plastic pipes without soldering, press fittings are often used (they are compression fittings) or new Belgian push-fittings that actually lock themselves.

Standard press fittings are usually made from steel alloy or cast iron. And they are best used for polypropylene or other small diameter plastic pipes. The advantage of these plumbing products is that they can be used to build transitions between pipeline elements and connect them at different angles.

Most often, fittings are placed on turns and branches of a plastic pipeline. An ordinary press fitting consists of a main body, a cover, a sleeve and two rings: a clamping one (it is located in a special socket) and a folded one (it is used to fix a plastic pipe).

If we are talking about fittings with a diameter of less than fifty millimeters, then they can be mounted manually, without additional devices and equipment. One more thing important rule. Before installing the fitting, the plastic pipe should be prepared - cut, deburred, cleaned of dust and degreased. Such preparation should be carried out in any case, regardless of the connection method chosen.

After plastic product will be brought to an acceptable state, it is necessary to install a nut previously removed from the fitting. Next, a clamping ring is put on this nut. Now you can insert the pipe into the fitting until it stops and fix it. The same actions must be done with the second connected pipe.

Flanged

It is possible to connect plastic pipes with flanges without soldering. Such a joint is considered very reliable - metal flanges can withstand huge positive temperatures and high pressures.

Today, even large-diameter pipelines are fitted with flanges. They provide a really strong connection.

Flanges for assembling household plastic pipelines are always threaded on one side only. As a rule, they are designed for a pressure of 1.6 MPa. At the same time, in stores you can find options for flanges with different section- from 20 to 1200 mm.

The connection algorithm using flanges is quite simple. First of all, you need to carefully pull the flange onto the pipe and put it on sealing gasket from rubber. The gasket should extend beyond the edge of the plastic pipe by no more than one centimeter. Then a flange is carefully pushed onto this gasket.

At the next stage, docking is carried out with exactly the same flange of another plastic pipe. And tighten the bolts here should be very careful. If you apply too much force, the plastic surface may crack.

With couplings

An ordinary coupling for plastic pipelines is a fairly simple part in its design. It consists of:

cast iron body;
two nuts;
rubber gaskets;
four metal washers.

The coupling can be found in the nearest plumbing store, or, if you have certain skills and knowledge, do it yourself. In this case, the characteristics of the coupling must strictly correspond to the dimensions of the connected products. Ordinary couplings are suitable for both pressure plastic pipelines and pipelines without pressure. With their help, they provide a reliable connection of polypropylene without the use of a soldering iron.

In order to form a joint, it is necessary to insert the ends of the pipes into the coupling so that they touch in the middle. The ends must pass through the washers, gaskets and nuts. Then you need to tighten the nuts tightly, so that the pressure on the gaskets is strong enough.

Docking plastic pipes with a coupling absolutely gives a sealed seam even without the use of soldering. But in certain cases, for example, if the pipe has a short length or is adjacent directly to the floor (or other horizontal surface), it is not possible to install an ordinary clutch.

For such difficult cases, a clamp-and-coupling coupling was invented. How to use it? First you need to clean the edge of the plastic pipe. Then you need to unscrew the coupling and put on the plastic product in the correct sequence all the fastening parts. Moreover, the sealing ring should eventually be located at a distance of at least one centimeter from the edge of the product.

Then, the body of the clamp-coupling sleeve itself must be inserted into the end of the plastic pipe. And then to this body you need to move all the available rings and tighten the bolt. And to the thread located on the other side of the coupling, it will be necessary to attach an “American” fitting with a plastic pipe connected to it.

To control the strength of the connection, it is necessary to carefully pull the coupling towards you, holding the pipe to which it is attached with your free hand. The clutch must remain stationary. If it moves, it means that the part of the wrong size was selected. That is why it holds so poorly on the pipeline. However, this is easy to fix - you just need to tighten the thread more tightly.

Gluing method

Plastic pipes can also be glued, although many plumbers consider this method to be extremely unreliable. And therefore, in practice, glue for connecting pipes is used only in combination with fittings.

Before applying the glue, the pipe is cut and burrs are removed from it. You also need to remove dust from it and thoroughly degrease those areas on which it is supposed to apply glue (that is, you have to buy special remedy for degreasing). Then you need to bring the pipe into the fitting to check how well they fit together.

Now you can apply a thin layer of glue to the place of future contact. Immediately after this, the pipe is inserted all the way into the fitting and held in this position for about two minutes so that the glue grabs. And the remains of glue that appear on the outer surface are removed with a cloth.

The glue will dry in about 15-20 minutes. However, it is necessary to let water (or something else) through the pipeline only not earlier than after 24 hours.

Some types of plastic (for example, the same polypropylene) are glued with great difficulty. In order for polypropylene parts to be well connected to each other, you will have to purchase high-quality glue specially designed for this material.

It can be concluded that there are plenty of ways to connect plastic pipes without using soldering. The coupling method is considered the most reliable of them, and gluing helps only in an emergency, and it must be used with caution.

Polypropylene pipes have long won great popularity among the consumer. Unlike metal options polypropylene pipes are much lighter in weight, and the methods of connecting this type of communications do not require skills in working with a welding machine and metal cutting tool, as is the case with iron pipes.

Peculiarities

As with any other type of plumbing, installation of polypropylene pipes has a number of features.

In butt welding, the walls should not be thicker than 4 mm. The mating surfaces must be trimmed, while strict parallelism of the connected elements must be observed. When docking, it is recommended to use special guides.
Since threading on a polypropylene pipe cannot be done, threaded fittings are used for threaded joints, and a sealant and Teflon tape are used to seal the connection.
When welding polypropylene pipes, it is imperative to ventilate the room. At negative temperature this type of work cannot be carried out indoors, since docking with insufficient heating of the elements does not guarantee the tightness of the connection.

At welding work with polypropylene pipes, it is necessary to heat the soldering iron to the desired temperature and install it on the stand. When working, safety precautions must be observed, as we are talking O high temperature, which is 260 C.

For high-quality connection of elements, it is necessary to withstand the melting time required for a certain pipe diameter.

Below are the diameters and time intervals.

16 mm - 5 sec;
20 mm - 6 sec;
25 mm - 7 sec;
32 mm - 8 sec;
40 mm - 12 sec;
50 mm - 24 sec;
63 mm - 40 sec.

What is necessary?

For the installation of polypropylene pipes you will need special tools for cutting and connecting elements.

The list of tools includes such devices as:

pipe cutter;
welding machine;
sweep;
glue gun;
marker for marking;
connecting part and tape measure.

pipe cutter for polypropylene pipes it is better to use a professional one - such a tool guarantees reliability and ideal even cut, it will prevent the formation of burrs on the cut surface. When choosing a pipe cutter, it is worth considering such important parameter as the minimum and maximum pipe diameter. The tool should be chosen with a blade made of alloy steel only.

Welding machine manual type must have a thermostat and a heating plate with holes for installing nozzles. The welding machine requires a pair of Teflon-coated nozzles. It should be selected from famous brands, which have proven themselves in the market, since the tool of dubious manufacturers may fail during operation, which will stop all work.

Stripping are manual and in the form of a nozzle on a drill.

Couplings with internal knives (shavers) are used for stripping the outer layer. Under the diameter of the pipe that is being cleaned, they select desired coupling. They also use double-sided couplings that allow you to work with different diameters. To clean the inner layer of the pipe, they take a stripper-facer, in which the knives are inside. The pipe is inserted into the tool and rotated several times.
Stripping in the form of nozzles on a drill differ from manual options only by the presence of a rod that is inserted into the tool chuck.

glue gun can be used as an alternative to other types of connections. This tool has two advantages: glued seams are almost as reliable as welded and other joints, and the glue sets quickly. Such connectors perfectly fasten shaped parts and other elements.

Ways

There are several ways to connect polypropylene communications. Choosing which method to use depends on the type of PP pipes and their purpose.

Cold welding based on gluing elements with a special adhesive composition. It is applied to the parts that need to be connected. First, the surfaces to be bonded must be degreased. After applying the glue, wait a while and connect the pipe with desired element. After a short period of time (approximately 20 minutes), the connection will stabilize and be reliable.

Connection using steel or cast iron fittings. This method is suitable for pipelines with a small diameter. Typically, fittings are installed on bends and ramifications of communications. The fitting includes such elements as a cap, a sleeve and a clamping ring, which is located in the socket of the product. The pipe is fixed with the help of a seam ring included in the design of the fitting.

When connecting with fittings, you must follow the step-by-step action plan:

the pipe cut must be made at a right angle;
all burrs on the surface to be joined must be eliminated;
then you need to install the nut from the fitting on the pipe and put a clamping ring on it;
after that, it is required to insert the pipe into the fitting and secure the connection with a clamping ring and nut.

The connection using flanges is considered very reliable, withstands high temperatures and high pressures. This method is used when it is necessary to connect polypropylene pipes without resorting to welding. For connection, bolts are used that are screwed into the thread of the flange.

When connecting with flanges, the following installation rules must be observed:

at the junction of the pipe, it is necessary to make a cut, avoiding the appearance of burrs;
the gasket that is installed on the cut must have a protrusion of 15 cm;
a gasket is placed on the flange and connected to another flange installed on another pipe to be connected;
gaskets must be installed in such a way that their cross section does not touch the bolts;
more than one gasket per flange cannot be installed, as this will reduce the tightness.

Connection using couplings. To connect with couplings on pipes, you need to make a thread for their subsequent installation and, for the tightness of the connection, wrap a little tow on it. The edges to be joined should be cut evenly and the location of the coupling should be marked with a marker. Then you need to apply grease to the coupling and install it on the pipe, at the previously marked place.

Welding refers to the hot connection method. This type of connection is one of the most reliable, and its essence lies in the melting of polypropylene with a special apparatus at a temperature of 260 C. The elements heated to the desired temperature are pressed tightly against each other, and after they cool down, a reliable connection is formed. The time after connection to the final polymerization of polypropylene will take 20 minutes.

Before proceeding with the connection by welding, it is necessary to remove all irregularities and burrs, and if the pipe has a layer of foil, then it must be treated with a trimmer.

When connecting by welding, the following sequence of actions should be observed:

turn on the welding machine and heat it up to a temperature of 260 C;
you need to put on the nozzles of the apparatus on the connected propylene pipes - this must be done very quickly;
when the elements to be welded begin to melt, they are removed from the apparatus;
connect the melted elements to each other by pressing firmly for 15 seconds;
the connected elements must be allowed to polymerize for complete setting - this usually takes about 20 seconds.

Common mistakes when connecting by welding:

displacement of elements during welding at the time of their heating;
when joining the elements, they cannot be rotated - otherwise the seam will turn out to be unreliable;
when welding the valves, the location of the valves was not taken into account, and they cannot move freely.

HDPE or PVC pipe can be connected by soldering. This is especially true for polyethylene construction.

How to connect?

In the case when you need to connect a polypropylene pipe to a metal one, you can use the threaded connection method. To do this, you will need special fittings, one end of which is smooth, and the other end is threaded for a metal pipe. With this type of connection, the diameter of the pipe should not exceed 40 mm.

The thread on the fitting can be either external or internal. Smooth surface with reverse side, needed for welding a plastic pipe. Mainly used for sealing linen tow, impregnated with drying oil.

Tow should be applied for a maximum of two turns and in the direction of the thread.

The sequence of actions for the threaded mounting method:

a pipe is cut at a right angle, its end is lubricated with grease, and then a thread is applied using a threading tool;
remove all chips from the thread and seal the joint with tow;
a fitting is screwed onto the pipe thread;
the opposite smooth end of the coupling is welded to the polypropylene pipe.

It is possible to connect polypropylene pipes both by welding and by cold method. The first option is preferred, as it is considered the most reliable and durable.

Welded connection

Before welding, polypropylene pipes and fittings for them must be treated with a degreasing solution, and then allowed to dry - only after this procedure can you proceed directly to welding. Similar preparatory work required for any type of PP pipe except for those reinforced with foil. At reinforced pipe the cut is cleaned with a special cleaning tool (shaver), into which the desired end of the pipe is inserted and rotated several times. After stripping, the upper part of the pipe must be degreased.

It is necessary to put a mark on the pipe with a marker, noting the desired distance for pressing it into the fitting. Then the end of the pipe must be put on the mandrel and the fitting inserted into the sleeve of the welding machine. All actions should be done very quickly and clearly. After that, the connected elements are heated for a strictly allotted time.

After the elements to be welded are melted, they must be removed from the nozzles and the pipe must be quickly pressed into the fitting. Some forces are required for the connection, since the elements to be welded must be pressed tightly and held in this position for a while. It is not worth clamping the joining elements for more than 20 seconds, since this time is quite enough for them to firmly grasp. After joining, be sure to let it cool down for a few minutes.

Standard in the past metal pipes Today, they are increasingly being replaced by plastic, or rather, polypropylene (as well as PVC). And if a welding machine is usually used to mount the former, then polymer analogues are mounted using a special soldering iron. However, the latter may not be at hand at the moment when it will be necessary to solder one of these pipes. Is there a way out of this situation? Actually - yes. In addition, here we will consider the soldering of wires.

Installation of water supply, sanitation and heating systems;
Repair work on heating and water supply systems;
The need to connect two wires;
Repairing the awning - sealing holes.

Is there an alternative to a professional soldering iron for polypropylene pipes?

Before dismantling the soldering of wires and awnings, let's dwell on the pipes. The apparatus for their welding costs several thousand rubles. Mostly professionals buy it for themselves, but for an ordinary person this device simply will not pay off. In this regard, it is necessary to look for an alternative option, which can become much more common in ordinary houses gas-burner.

Such a burner perfectly shows itself both in repair and in installation. At the same time, it can be soldered as pipes of small diameter, as well as rather large analogues. It is used not only for connecting pipes, but also as a means of installing plastic taps to control the flow of water into the pipeline.

Tips for connecting polypropylene pipes without a soldering iron

The quality of the connection largely depends on the cleanliness and absence of grease on the pipes themselves. Therefore, before work, it is recommended to degrease and clean them from dirt;
All pipes, as well as fittings and other parts must be from the same manufacturer. So you will be sure that the same temperature effect must be applied to connect them. In addition, you should not save on quality. Its absence can manifest itself both during the soldering process and during subsequent operation;
Do not solder in cold conditions. If, for some reason, the temperature in the room has dropped by less than +5 degrees, the connection may be fragile;
It is recommended to practice on unnecessary pipe sections.

Alternative - PVC pipes

There are plastic pipes that do not need to be soldered, as they can be glued together. In addition, they have all-plastic pipe threads located on the inner and outer sides.

In addition, for PVC and CPVC pipes, there is a special solvent-based cement. After treatment with such cement, the surface becomes soft and can be quickly glued.

The procedure for soldering polypropylene pipes

Drafting detailed diagram, marking the places of turns, the location of cranes, corners and other elements of the system;
Pipe cutting. It is best to take with a margin of 25 millimeters, which will be fused onto the fitting;
The pipe and fitting are heated with a burner. The temperature at the same time is approximately 280 degrees Celsius;
The fused elements are held together until they cool.

A universal way to solder an awning

With the advent of the warm season, the need for tents increases. By putting on your local area or taking a small tent for a picnic, you can find an unpleasant surprise- a hole. Is it worth it to buy a new awning after that or can I somehow fix the situation?

For soldering we need building hair dryer, which will have a special crevice nozzle, as well as a patch with a roller. After preliminary cleaning of the place of damage and patching of dust and grease, it is necessary to lay the awning on a flat surface. Having attached a patch to it, we begin to heat up both surfaces with the help of a crevice nozzle, simultaneously fastening it with a roller. The better you heat the surfaces, the better they stick to each other. But here it is extremely important not to overdo it and not burn a hole.

Soldering wires without a soldering iron using a soldering tape

Although regular soldering iron found in our homes much more often than its analogue for plastic pipes, it still may not be at hand in right moment when you need to connect two wires. Of course, you can try to twist them and wrap them with “blue electrical tape”, but this option is only temporary. At the same time, you can connect the wires “forever” without a soldering iron.

A special soldering tape will help us with this, which allows you to create a strong polymer layer around the wire, providing a complete connection and insulation. problem area. The steps for working with this tape are as follows:

Stripping the wires that we will connect and their subsequent twisting;
Removing the protective layer from the tape and wrapping around the place of twisting;
Heating the tape with an open flame until it melts and evenly covers the problem area. For this, ordinary matches are suitable;
After the tape has cooled, remove the excess flux. The wire is fully connected and ready for further use.

Welding wires with a special paste

Paste is used to connect various metals such as steel, nickel, copper and others. The reason for this versatility is that this material is produced on the basis of silver. In general, the paste contains flux, solder and binders ground to a state of powder. In the vast majority of cases, this method is used for soldering small wires. So, if your favorite headphones are out of order, and there is no soldering iron at hand, then ideal solution it will be pasta. The way to use it is very simple:

We clean the wires and twist them together;
We apply the paste to the place of twisting as evenly as possible;
With help ordinary lighter the paste is heated until it melts and turns into a full-fledged soldering;
After this place it is necessary to isolate all bare parts of the wire. The ideal remedy for this is a heat shrink sleeve. We put it on the place of soldering, after which we warm it up and get reliable insulation.
