Homemade soldering iron for plastic pipes. Soldering polypropylene pipes with your own hands using an example - instructions. General technological methods for welding polypropylene pipes

Plastic plumbing has come into our everyday life for a long time. An invariable attribute of the repair of the Soviet housing stock, along with metal-plastic windows, became a water pipe made of poly propylene pipes.

Advantages polypropylene water pipe before steel pipes are obvious:

• Cheapness and wide choose materials;
• Simplicity of work on marking and assembling the most intricate and complex pipe routing options;
• Environmental friendliness, resistance of the material to corrosion and salt deposits on the walls of polypropylene communications.

Those who have encountered the tedious and time-consuming procedure of installing a water supply system from metal pipes can appreciate simple technique connecting plastic using a special soldering iron for polypropylene pipes.

If the time has come to renovate the apartment, the problem of replacing the water supply with plastic communications, depending on the availability of desire, money and free time, can be solved:

• Hiring a craftsman and a friend who has experience working with a device for soldering propylene pipes, who can help assemble the pieces marked and cut into a single whole using a soldering iron plastic pipes;
• Transferring the issue of turnkey repairs to a team of repairmen without any desire to understand the intricacies of assembling and soldering plastic components;
• Doing all the work yourself.

The simplicity of assembling the soldering of plastic is so captivating that it is difficult to resist the temptation and solve the problem of plumbing in no other way than to choose and buy a soldering iron for polypropylene pipes.

The amount of money spent on purchasing the tool will be less than the cost of the specialist’s services, but provided that you really understand how to choose a soldering iron for polypropylene pipes. Essentially, the soldering iron for propylene parts and connecting fittings is a heating element with thermomechanical or electrical system heating control and indication. Two nozzles are mounted on the heater, allowing you to simultaneously heat the outer surface of the pipe and inner surface fitting. Heating lasts on average about 5s, the parts are connected with slight pressure hands to grasp and form a strong connection within 2-3s. If parts are overheated or connected lopsidedly, some of the molten plastic may get inside the pipe, and as a result, the flow area decreases.

Important ! Doing most of the soldering and assembly work, you are able to personally control the quality of soldering connections of polypropylene pipes.

For innovators and DIY enthusiasts, you can assemble a soldering iron for polypropylene pipes with your own hands. The strength and durability of the soldering depends on the perfection of the soldering iron and how high-quality the polypropylene pipes are.

What is good about a DIY soldering iron?

The operating principle of the soldering iron is simple and uses the principle of adhesion of the soldered surfaces of polypropylene parts heated to the softening temperature. There is not always a need to rewire or resolder half of the wiring water supply networks in the house. Sometimes you need to work with a soldering iron to make two or three connections. In this case, a homemade, do-it-yourself mini-soldering iron for polypropylene pipes from a handy heater can help out.

For someone with experience working with electrical wiring and using plumbing skills, making a small amateur version of a soldering iron for polypropylene pipes is a matter of two hours.

As a rule, water pipes are laid in channels and hidden from prying eyes with screens and decor, so you don’t have to worry about beauty and aesthetic appearance. Another thing is important - incorrect temperature adjustment and overheating of the pipe or fitting material, even under slight force, will lead to defects. In soldering, the first and main issue remains the quality of the connection of parts.

If, when working with a homemade soldering iron, you may fall slightly short of world standards appearance- no problem, for amateur cases this is allowed.

For assembly homemade soldering iron propylene pipe you will need:

• The heating element is the soleplate of a conventional electric iron, preferably in the form of a closed aluminum block with a thermostat and electric cord with fork;
• soldering iron attachments for polypropylene pipes and fittings required size for your pipes;
• nickel-plated M8 bolt-nut for attaching nozzles to the heater;
• digital multimeter with external thermocouple thermometer;
• a clamp or other fastening that allows you to securely fix the soldering iron on a utility surface.

In addition to temperature, the speed or power of heating the surface of the parts being joined is important. If heated polypropylene fitting or a pipe for a long enough time - the parts will lose their shape and geometric dimensions under the influence of temperature.

Therefore, to quickly melt a surface with a diameter of 15-30 mm, a power of 700 - 900 W is required, which approximately corresponds to maximum power iron heater.

We assemble a homemade product for propylene couplings:

1. At a distance of 30-40 m from the nose of the aluminum sole, we drill a through hole with a diameter of 8 mm and, using a screw and nut, connect the nozzles for the pipe and fitting to the base of the heater;
2. We install the iron handle on the heater sole so that it does not limit access to the attached attachments;
3. We connect the wiring to the contacts of the iron heater;
4. We turn it on and use a multimeter, a digital thermometer and a regulator on the iron to set the temperature to 265 o C.

We use a clamp to fix a homemade soldering iron of polypropylene pipes, which will allow you to solder parts yourself, without an assistant; the handle can also be made to suit you for the greatest convenience and minimal risk of getting burned.

Which soldering iron is better for polypropylene pipes

It has always been believed that the best tool is professional option, designed for long-term use and with high parameters for soldering propylene pipes. A professional soldering iron for polyethylene pipes requires:

• The use of materials for nozzles that are resistant to prolonged heating, with high thermal conductivity, and that do not stick to the heated surface of the polypropylene part; as a rule, brass or copper tips, coated with Teflon or carbon fiber;
• Easy and convenient change of nozzles on the heater flange; the kit includes a set for the main pipe sizes - from 16 to 160 mm;
• The metallized surface of the nozzles gives high speed heating polypropylene parts;
• The presence of a heater power supply stabilizer and automatic temperature regulation allows you to keep the soldering iron hot for as long as desired without the risk of failure of the heating element.

Mandatory attributes of professional models of soldering irons are an easily removable stand and a case for storing and carrying the device with accessories.

For your information ! U original models soldering irons, unlike counterfeits, markings and information about the model are applied typographically to the body or to a metal substrate plate tightly sealed into the plastic. On fakes, the marking is pasted in the form of a metallized label and is easily separated from the soldering iron body.

For example, the widely known version of the soldering iron for polypropylene pipes is dytron or ditron - as you like. He is highly praised for his reliability and ease of use, unpretentiousness and robust construction. When soldering propylene parts, time passes by seconds; you have to quickly set up, drop or even throw the pin on the stand, and this practically does not affect its performance. There are three models in the DYTRON line:

• Power 850 W, the most popular in apartment renovation, used for polypropylene pipes with a diameter of up to 36 mm;
• Power 1200 W - for polypropylene pipes with a diameter of up to 160 mm;
• With a rod-shaped heater with a power of 650 W.

The soldering iron comes with a key for changing nozzles, which can be from 3 to 12 in a set, scissors for cutting polypropylene pipes, building level, gloves and stand. Despite all the advantages, it is worth noting one negative point - the clearly overpriced soldering iron.

Important ! Such devices are designed for many hours of operation, but in any case, they require careful care. non-stick coating on the nozzles. Teflon is very sensitive to scratches and chips, so you should not use hard or metal objects other than rags for cleaning.

But even specialists involved in soldering water pipes do not always strive to buy a soldering iron for polypropylene pipes in an expensive professional version. Many of the budget models, assembled from Chinese or Turkish components, work just as well as branded models.

Let's take for example a typical workhorse repairman - soldering iron for polypropylene pipes "Soyuz":

• High heater power - up to 2 kW;
• The kit includes six standard nozzles with a diameter from 20 to 63 mm;
• In addition, the soldering iron is equipped with a hexagon wrench for changing the working tool, a stand for the device and a case.

Length power cord is only 130 cm, which is clearly not enough for work. But this size is typical for budget models, while professional soldering irons have a full 2.5-3.5 m. The Soyuz is equipped with a two-mode push-button heating control system and two color indicators - green and red, the latter lights up when the heating is turned on automatically.

The soldering iron is equipped with everything necessary for successful soldering of polypropylene pipes, so it’s difficult to say whether it’s worth overpaying for additional accessories, as in the case of expensive models of soldering irons.

Choosing a soldering iron for polypropylene pipes

Polypropylene pipes today have almost completely replaced the previously used metal pipes. However, if the latter were connected exclusively through threaded connections, then to connect plastic parts today they use special equipment, tools. One of them is a soldering iron for polypropylene pipes (it is sometimes called an iron).

This device is especially popular among craftsmen who independently install heating systems and plumbing, without the help of specialized companies. What characterizes this popular instrument today?

Types of soldering irons

The design of the machine for soldering polypropylene pipes is quite simple. It consists of a heating element that transfers heat metal plate having holes for nozzles.

The main task of the soldering iron is to maintain the desired temperature at a constant level. The main difference between these devices is the method of attaching the nozzle to the heating surface.

In Russia, sword-shaped soldering irons and corresponding nozzle designs are more common. This is due to the relatively low price and large assortment. However, among professional tools More and more often you can find cylindrical heating devices.

Soldering iron for soldering sword-shaped polypropylene pipes

Another main criterion when choosing a soldering iron is constant temperature. The reliability of the pipe connection depends on this characteristic. On sale you can usually see a whole set for soldering pipes. It includes the soldering iron itself, several attachments, and sometimes the kit is supplemented with scissors for cutting pipes.

Soldering iron power for polypropylene pipes

The heating speed depends on its value. All tools of this kind are designed to use a 220 volt network. For installing pipes at home, a soldering iron with a power of 700 to 1200 watts is suitable.

The minimum power is sufficient for soldering pipes with a diameter of 16-63 mm. When connecting pipes with a diameter of 75 mm, you will need a soldering iron with an output of at least 850 W. And 1.2 kW must be used when soldering products with a diameter of up to 125 mm. In any case, when independent connection You will need a soldering iron for soldering polypropylene pipes with a power of no more than 1.5 kW.

Any soldering machine is equipped with a thermostat located directly on the body.

Optimal temperature for soldering +260С. At a lower temperature, the pipe fits into the nozzle for too long and too tightly, which does not ensure a good connection between the fitting and the pipe.

The thermostat automatically turns off the tool when the set temperature is reached (this is indicated by a light bulb or LED).

Iron attachments

Most efficient use soldering iron is possible only if several attachments are installed on it at the same time. And indeed, change them when the soldering iron is hot #8212; a very dubious pleasure. Produced nozzles for soldering iron polypropylene pipes allow you to connect products different diameters.

Welding machine complete with nozzles

In the manufacture of nozzles, to increase their strength and durability, they use various coatings. Most often this is Teflon (or metallized Teflon, which is a more durable option).

To extend their service life, before starting soldering, be sure to remove any melt residue left after previous works.

Cost of the device and fittings

All manufacturers recommend using a soldering iron for plastic pipes with a diameter of 16-63 mm, with a power of 680 W. If it is necessary to connect pipes with a diameter of up to 75 mm, then the power should be greater - up to 850 W. When working with large diameters, up to approximately 125 mm, experts recommend using soldering irons with a power of 1200 W.

Soldering iron attachments

Soldering iron attachments for pipes. The size of the nozzle depends on the diameter of the plastic pipe

As a rule, when connecting polypropylene pipes in large volumes, already ready-made blocks. But this is not always beneficial for the home; there may be a need to install just a few separate pipes, so when choosing a soldering iron specifically for home use It is necessary to pay attention to the presence of all attachments.

You also need to pay attention to the material of manufacture; it can be metallized Teflon or regular Teflon. At the same time, the first one is higher, it requires a careful, careful attitude. They must be wiped before use isopropyl alcohol.

Temperature level adjustment

When choosing a soldering iron for installing plastic polypropylene pipes, you must close attention pay attention to the possibility of adjusting the temperature level. Adjustment accuracy from one to five degrees can be achieved using only a professional soldering iron, but it will be needed when the volume of work is very large. At home, you can often get by with cheaper models, but you should still choose them carefully.

The temperature when connecting parts should not be equal to or greater than 270 degrees, since at this value the thermal degradation of polypropylene pipes begins. Optimal value is to support a temperature value of 260 degrees, so when choosing, make sure that the rhythm of the difference is not too large.

When choosing, remember that attention should be paid to the temperature not on the soldering iron regulator, but on the nozzle. Experts recommend purchasing an additional special thermometer, which will allow you to accurately determine the temperature value so that the soldering is of high quality and the pipe itself is not damaged. Besides , modern models devices have sound alarm: When a certain value is reached, an alarm will sound. Such devices allow you to monitor the condition in three modes (for heating, for connecting polypropylene pipes, for fixing).

When buying a soldering iron for plastic pipes, you need to pay attention to every little detail, since the quality of installation and the pipe itself often depends on them. A soldering iron for plastic pipes must not only be reliable, but also have the ability to control temperature, be easy to use, and have all the necessary attachments.

Soldering iron for plastic pipes

Quite often, when carrying out repairs or during the construction of buildings, it is necessary to carry out pipelines. Modern technologies allow the use of plastic pipes in almost all communications. made from durable polymers. Plumbing plastic pipes, despite their high strength, have a low price, are not afraid of corrosion and do not become overgrown inside with deposits of salts and lime.

Hot and cold water supply in the apartment, laying water supply on summer cottage and installation of pipelines when installing heating systems - plastic pipes are used everywhere. Special soldering irons are used to work with polymer pipes. which perform heating of pipes and other pipeline elements (angles, tees, crosses). The connected heated parts of the pipeline are soldered into a single whole and do not allow water to pass through, which is what is required from the plumbing or heating system.

A soldering iron for plastic pipes is sold in almost any household or hardware store. Their cost is relatively low, especially when you compare their price and the cost of work on laying water lines in an apartment or house, which the craftsmen will require from you. Of course, if you need to add a tee to install a washing machine, then there is no point in purchasing a soldering iron - it’s easier to call a mechanic from the housing office. But if the renovation of an apartment or house is major, then a soldering iron for plastic pipes will pay for itself quite quickly.

The operating principle of a soldering iron for plastic pipes is simple - inside it there is a heating element, which is heated by a voltage of 220 V, and from it the nozzles for pipes and other elements are heated. The nozzles, which are sold as a set along with the soldering iron, have a diameter of #189; up to 2 inches and allow you to perform necessary work With various pipes. The tips are screwed onto the soldering iron with different sides, which allows you to simultaneously heat the pipe from the outside and the connecting element from the inside.

However, it is best to work with a soldering iron with a partner, when one holds the soldering iron, and the second heats up the necessary sections of the pipeline. But if there is no partner, then you can do it yourself, but this will require skill and work gloves - so as not to get burned. Special scissors are included with the soldering iron. which allow high-quality cutting of plastic pipes various sizes. Of course, you can cut the pipe with a hacksaw, but scissors will do it much faster.

When buying a soldering iron for plastic pipes, you need to pay attention to the presence of a rheostat on the soldering iron, which serves as a temperature regulator. At the maximum temperature level, a soldering iron that is turned on will not only generate extra kilowatts for you, but can also unnecessarily melt plastic pipes. This usually happens in hard to reach places, where it is not possible to work comfortably and excessive use of a soldering iron greatly melts the pipe or the joining element (tee, angle, cross, joining barrels). During operation, it is better to regulate the set temperature than to redo a certain section of the pipeline several times.

Of course, when carrying out repair work Other power tools will also be required. and the tools. But the soldering iron is for polymer pipes When carrying out plumbing work or installing a heating system, it will come in handy.

The ability to assemble pipelines yourself is a definite plus polypropylene products. Using convenient and lightweight material, you can build a sewer system yourself, repair and modernize the water supply system.

The main thing is to understand the specifics of connecting prefabricated elements to each other. Agree, this is an important part of the work, responsible for the tightness of the highway and its trouble-free operation.

We offer you detailed information about how polypropylene pipes are soldered, what equipment is used in the work, and also list the most common mistakes made by novice welders.

The information we offer will help you build trouble-free communications. For clarity, the article is supplemented with graphic applications and a video guide.

The soldering process is carried out due to the pronounced thermoplastic properties of the material. Polypropylene softens when heated - it acquires a state similar to plasticine.

This is what a soldering iron (“iron”) for polypropylene pipes looks like. Simple electrical device, semi-automatic, thanks to which plastic soldering is done

To be completed butt welding soldering machine designs differ increased complexity. Typically, such equipment contains not only a heating element, but also a system for centering the parts being welded.

As a rule, direct welding equipment, like the technology itself, is rarely used in the domestic sphere. Priority of use is industry.

More complex device, with the help of which precise alignment of the welded parts is carried out with further process heating and soldering. Used with direct welding technology

In addition to soldering irons, the master will also need:

• scissors - ;
• construction tape;
• bench square;
• shaver for pipes with reinforcement;
• marker or pencil;
• surface degreasing agent.

Since the work is performed on high-temperature equipment, you should definitely wear thick work gloves.

Polypropylene Welding Procedure

Important warning! Welding work polymer materials must be carried out in conditions of good ventilation of the room. When heating and melting polymers, they release toxic substances, which in a certain concentration have a serious effect on human health.

The procedure for welding polypropylene is simple, but it requires precision and accuracy in work. You should also avoid common mistakes, such as insufficient or excessive heating

The first thing you need to do is prepare for work:

1. Install blanks of the required diameter on the heater plateau.
2. Set the regulator to 260ºС.
3. Prepare the mating parts - mark, chamfer, degrease.
4. Turn on the soldering station.
5. Wait for dialing operating temperature– turn on the green indicator.

Place the mating parts (pipe - coupling) on ​​the blanks at the same time soldering station. In this case, the polypropylene pipe is inserted into the internal area of ​​one blank, and the coupling (or socket of the shaped part) is placed on outer surface another blank.

Typically, the ends of the pipe are inserted along the border of the previously marked line, and the coupling is pushed in until it stops. Enduring polypropylene parts on heated blanks, you should remember important nuance technology – holding time.

Conclusions and useful video on the topic

There is always something to learn from professionals. You can see how to work with polypropylene in the following video:

Installing polymer pipelines by hot soldering is a convenient and popular technique. It is successfully used in the installation of communications, including at the household level.

People without extensive experience can use this welding method. The main thing is to correctly understand the technology and ensure its execution exactly. A technological equipment can be bought or rented.

Do you have experience soldering polypropylene pipes? Please share information with our readers. You can leave comments and ask questions on the topic in the form below.

Do you want to repair or replace communications made of polymer pipes? Agree that it’s not a bad idea to save on calling a technician by assembling a new pipeline yourself. But you don't know how to connect individual elements systems among themselves and what is needed for this.

The article we presented describes in detail the technology of welding polypropylene pipes - any novice plumber can connect them with his own hands. We will tell you what you need to consider, how to use a soldering iron for joining plastic elements. We will tell you in what cases other methods are used.

To help the novice master, we have selected detailed videos demonstrating step by step process performing polypropylene welding, and photo illustrations.

One of the undeniable advantages of polymer pipes is their ease of assembly.

Installation of elements can be done almost anywhere: laying open method on the walls or placed hidden under the floor.

If the welding of polypropylene water pipes is carried out correctly, then assembled system will serve without repair for more than a dozen years

Polymer pipes are produced with diameters from 20 to 110 mm. For household purposes, products of sizes 20/25/32/40 mm are most often used. The area of ​​application determines the indicator nominal pressure material.

In the marking it is indicated by the letters "PN":

• PN 10– chosen for arranging cold water supply.
• PN 16- used for cold water, but with higher pressure, as well as when installing a “warm floor” system.
• PN 20– products, the only limitation of which is temperature regime liquids transported through them. It should not exceed 75 °C.
• PN 25– universal products used for arranging both “cold” and “hot” systems, the temperature of which reaches 90 °C.

On sale you can find polymer products equipped with additional reinforcement.

Reinforced products are used for laying over long sections in conditions where it is necessary to reduce linear expansion that occurs during temperature fluctuations

The main feature of polymer pipes is their inability to bend.

Therefore, all changes in the trajectory of the laid highway are carried out only from straight sections connected to each other by auxiliary fittings:

• crosses– for the possibility of branching the main flow;
• tees– flow multipliers;
• couplings– for connecting pipes in a straight section;
• bends– for changes in pipeline direction.

Fittings can be equipped with fused metal thread, which makes it possible to connect a polymer pipeline with metal elements.

To ensure that the seams are as strong and airtight as possible, it is important to ensure that the diameters of the joined elements match exactly

When choosing auxiliary elements, two parameters should be taken as a basis: the internal cross-section of the products and the thickness of their walls. These parameters must match technical specifications polypropylene pipes used.

Methods for connecting polymer pipes

When joining pipes made of polymer materials, depending on the installation conditions, one of two methods is used:

1. Soldering– involves heating and joining the molten ends of the elements.
2. No soldering– involves connecting pipes through compression fittings or by implementing so-called “cold” welding.

The second installation method is convenient in the sense that there is no need to use special equipment to implement it. All work can be done using simple tool– crimp key.

Polypropylene pipes, due to their low cost and ease of connection, are used by many owners when installing water supply in an apartment or house. There are many tools for soldering pipes, but not everyone can afford them, so I made a soldering iron from an old electric iron.

On the “sole” from the iron (heating element) (photo 1, item 1) in advance drilled hole Using a bolt on both sides, I secured the heating element for the outer (7) and inner (see photo 2) diameters of the pipes. The heat-insulating casing (photo 1, item 2) and the temperature controller module (3), mounted on a textolite plate (4), were connected to the heating element and installed on a stand (5). PTFE insulators (6) were placed between the casing and the plate.

The aluminum stand securely holds the structure, and the protruding part of the textolite plate is freely inserted into its groove (8) and easily removed, which allows you to conveniently store the device. Wooden handle I attached it to the textolite with self-tapping screws. The temperature controller module was assembled according to the diagram...

When installing a water pipeline, I turn on the soldering iron and set the desired temperature. I insert 25 mm diameter pipes into the heating element on both sides for no more than 5 seconds, take them out and solder them together, connecting the heated ends.
