Metal pipes, which were standard in the past, are today increasingly being replaced by plastic ones, or more precisely, polypropylene (as well as PVC). And if a welding machine is usually used to install the former, then the polymer analogues are mounted using a special soldering iron. However, the latter may not be at hand at the moment when it is necessary to solder one of these pipes. Is there a way out of this situation? Actually yes. In addition, here we will look at soldering wires.

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

Before we sort out the soldering of wires and awnings, let's focus on the pipes. The machine for welding them costs several thousand rubles. Mostly professionals buy it for themselves, but for ordinary person This device simply won’t pay for itself. In this regard, we have to look for an alternative option, which could be a gas burner, which is much more common in ordinary homes.

This burner performs well both in repair and installation. At the same time, it can solder both small-diameter pipes and fairly 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. This way you will be sure that the same temperature effect must be applied to connect them. In addition, you should not skimp on quality. Its absence may appear both during the soldering process and during subsequent operation;
Do not solder in cold conditions. If, for some reason, the room temperature has dropped by less than +5 degrees, the connection may be fragile;
It is recommended to practice on unnecessary sections of pipe.

Alternative – PVC pipes

There are plastic pipes that do not require soldering, since they can be glued together. In addition, they have all-plastic pipe threads located on the internal and external sides.

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

The procedure for soldering polypropylene pipes

Drawing up a detailed diagram, marking turning points, location of taps, 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 using a burner. The temperature is approximately 280 degrees Celsius;
The fused elements are held together until they cool.

A universal method of soldering an awning

With the arrival of the warm season, the need for awnings increases. When you put it out on your property or take a small tent for a picnic, you may find an unpleasant surprise - a hole. Is it worth buying a new awning after this or can I somehow correct the situation?

For soldering, we need a construction hair dryer, which will have a special crevice nozzle, as well as a patch with a roller. After preliminary cleaning the damaged area and patching it from dust and grease, it is necessary to place the awning on a flat surface. Having attached the patch to it, we begin to heat both surfaces using a crevice nozzle, simultaneously securing it with a roller. The better you heat the surfaces, the better they will 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 soldering tape

Despite the fact that a regular soldering iron is found in our homes much more often than its counterpart for plastic pipes, it still may not be at hand at the right time 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 wires “forever” without a soldering iron.

A special soldering tape will help us with this, which allows us to create a durable polymer layer around the wire, providing a complete connection and insulation of the problem area. The stages of 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 it around the twisting area;
Heating the tape with an open flame until it melts and evenly covers the problem area. Regular matches are suitable for this;
After the tape has cooled, remove excess flux. The wire is fully connected and ready for further use.

Welding wires using special paste

The paste is used to join 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 binding components crushed to a powder state. In the vast majority of cases, this method is used for soldering small wires. So, if your favorite headphones are out of order, and you don’t have a soldering iron at hand, then paste is the ideal solution. The way to use it is extremely simple:

We clean the wires and twist them together;
Apply the paste to the twist area as evenly as possible;
Using a regular lighter, the paste is heated until it melts and turns into a full-fledged solder;
After this, it is necessary to insulate all exposed parts of the wire. The ideal means for this is a heat shrink sleeve. We put it on the soldering area, then heat it up and get reliable insulation.

When creating modern utility networks, craftsmen are forced to solve the problem of how to connect plastic pipes for water supply. Connection technologies vary depending on the specific system type and other operating conditions.

Plastic has practically replaced cast iron and steel in the construction of communications. Polymer pipes do not require expensive equipment or specific qualifications of a craftsman to connect.

Connecting plastic water pipes with your own hands can be done using different technologies. Their choice depends on the purpose of the system, the type of polymer used and the dimensions of the pipe. The main types of connection are:

In general, it is possible to connect plastic pipes both without welding and with it, that is, installation can be carried out “hot” (welding) or “cold” method.

The most rational way to install a water supply system is. What are its advantages and features - read in a separate article.

How to organize water supply in a private house from a well is described.

Non-welding connection for various types of plastic pipes

Connecting plastic pipes without soldering can be done in various ways. The choice of specific technology depends on the type of polymer water supply:

1. Polyethylene pipes HDPE connected using . No specific equipment is required for installation; muscular effort or, in extreme cases, a crimp wrench is sufficient. This DIY installation of plastic pipes will be simple, but it will take some time, since each joint will need to be carefully crimped. In addition, this method is still less reliable compared to soldering.

Features of connecting plastic and metal pipes

Connecting plastic pipes with metal pipes is necessary in cases when repairing an old sewer or water supply system where steel or cast iron elements are present.

If plastic and cast iron pipes are joined in a sewer system, then installation of the joint is very simple, using special adapters, which are available in various sizes. But the methods that are traditionally used for joining cast iron pipes are not suitable in the case of plastic. In particular, due to embossing, the plastic pipe is deformed, and there will be no question of the reliability of the connection. It is also not advisable to seal the joint between a polymer and cast iron pipe with cement - after all, plastic and cast iron expand differently due to heating - it will be enough to fill the pipes just a few times hot water so that the connection loses its tightness and becomes unusable.

How to connect plastic water supply pipes with metal ones? Greater reliability will be required here, since the pressure in the water supply system is higher. In particular, if the water supply is created from pipes up to 4 cm in diameter, then the joint is created using an appropriate fitting. It will have a thread on the metal side, and a standard coupling on the plastic side.

Important: Do not forget to carefully seal the connection on the side of the metal pipe - traditional materials and technologies, for example, flax fibers impregnated with drying oil, are suitable for this.

If we are talking about installing a pipeline with a diameter exceeding 40 mm, then it is advisable to use a flange connection to connect metal and plastic parts. This greatly simplifies the installation process, especially since it will not be difficult to select the appropriate adapters.

And when pipelines are assembled from different materials, where the environment will be under high pressure, then it is worth using a metal hose. To attach such a part to a plastic part, you will need an appropriate fitting, and it is attached to metal with a threaded connection.

In this way, you can create the most reliable joint and move from old metal structures to more practical and durable plastic ones. These methods are applicable for both heating and plumbing systems.

Do-it-yourself installation of plastic pipes: video

In this video section you can see how plastic pipes are connected without soldering into a socket.

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

Peculiarities

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

When butt welding, the walls should not be thicker than 4 mm. The joining surfaces must be trimmed, and strict parallelism of the connected elements must be maintained. When docking, it is recommended to use special guides.
Since threading cannot be done on a polypropylene pipe, threaded fittings are used for threaded connections, and a sealant and Teflon tape are used to seal the connection.
When welding polypropylene pipes, it is necessary to ventilate the room. When the temperature in the room is below freezing, this type of work cannot be carried out, since joining when the elements are insufficiently heated does not guarantee the tightness of the connection.

When welding with polypropylene pipes, it is necessary to heat the soldering iron to the required temperature and place it on the stand. When working, you should observe safety precautions, since we are talking about high temperature, amounting to 260 C.

To ensure a high-quality connection of elements, it is necessary to maintain 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?

To install polypropylene pipes, you will need special tools for cutting and connecting elements.

The list of tools includes such devices as:

pipe cutter;
welding machine;
stripping;
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 a perfectly even cut, it will not allow the formation of burrs on the cut surface. When choosing a pipe cutter, it is worth considering such an important parameter as the minimum and maximum pipe diameter. You should choose a tool 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 chosen from well-known brands that have proven themselves in the market, since tools from dubious manufacturers may fail during operation, which will stop all work.

Stripping can be done manually or in the form of an attachment to a drill.

To strip the outer layer, couplings with internal knives (shavers) are used. Select the required coupling for the diameter of the pipe being cleaned. They also use double-sided couplings that allow you to work with different diameters. To strip the inner layer of the pipe, use a trimmer with knives located inside. The pipe is inserted into the tool and rotated several times.
Grinding tools in the form of drill attachments differ from manual versions only in 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.

Methods

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 is 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 to the 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 branches of communications. The fitting includes elements such as a cover, a sleeve and a clamping ring, which is located in the socket of the product. The pipe is fixed using the seam ring included in the fitting design.

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

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

Connections using flanges are considered very reliable and can withstand 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 flange thread.

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

at the pipe connection 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;
The gaskets must be installed in such a way that their cross-section does not touch the bolts;
More than one gasket cannot be installed on a flange, as this will reduce the tightness.

Connection using couplings. To connect with couplings, you need to make a thread on the pipes for their subsequent installation and, to make the connection tight, wrap a little tow around 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 lubricant to the coupling and install it on the pipe in the previously marked place.

Welding refers to the hot joining method. This type of connection is one of the most reliable, and its essence lies in the melting of polypropylene with a special apparatus under the influence of a temperature of 260 C. The elements heated to the required temperature are pressed tightly against each other, and after they cool, a reliable connection is formed. The time after joining until 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 to a temperature of 260 C;
you need to put the device nozzles on the propylene pipes to be connected - this needs to be done very quickly;
when the elements to be welded begin to melt, they are removed from the apparatus;
connect the molten elements to each other by pressing firmly for 15 seconds;
The connected elements must be allowed to polymerize to fully set - this usually takes about 20 seconds.

Common mistakes when connecting by welding:

displacement of elements during welding at the moment of their heating;
when joining elements, they must not be rotated - otherwise the seam will 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 has a thread for metal pipe. With this type of connection, the pipe diameter should not be more than 40 mm.

The thread on the fitting can be either external or internal. A smooth surface on the reverse side is needed for welding a plastic pipe. For tightness, linen tow impregnated with drying oil is mainly used.

The tow should be applied to a maximum of two turns and in the direction of the thread.

Sequence of actions for the threaded installation method:

the pipe is cut at a right angle, its end is lubricated with grease, and then a thread is applied using a thread-cutting tool;
remove all shavings 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.

Polypropylene pipes can be connected either by welding or cold. Greater preference is given to the first option, since it is considered the most reliable and durable.

Welded joint

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 is necessary for any type of PP pipes with the exception of those reinforced with foil. For a reinforced pipe, the cut is cleaned using a special cleaning tool (shaver), into which the desired end of the pipe is inserted and turned several times. After cleaning, the upper part of the pipe must be degreased.

You must mark the pipe with a marker, marking the required distance to press it into the fitting. Then the end of the pipe must be placed on the mandrel and the fitting must be inserted into the sleeve of the welding machine. All actions should be done very quickly and clearly. After this, the connected elements are heated for a strictly allotted time.

After the elements to be welded have melted, they must be removed from the nozzles and the pipe quickly pressed into the fitting. The connection requires some force, since the elements to be welded must be pressed tightly and held in this position for some time. You should not clamp the joining elements for more than 20 seconds, as this time is quite enough for them to firmly set. After connecting, be sure to let it cool for a few minutes.

To independently install a water supply system from plastic pipes, you do not need a lot of knowledge and experience, since this process is not complicated. However, to improve the quality of the work performed, it is necessary to become familiar with the technology and some of the nuances of connecting pipe elements of this type. It is also important to learn a few lessons about how to connect different types plastic pipe and the main points of this process.

Methods for connecting plastic pipes

Firstly, it is worth noting that plastic pipes include products made from the following materials:

Polypropylene.
Metal-plastic.
Polyethylene.
Polyvinyl chloride.

Each material has certain properties, therefore, the connection of products is carried out different ways, including soldering polypropylene pipes without a soldering iron (read also: “How to connect polypropylene pipes - a review of proven joining methods”). For greater awareness, it is worth learning how to connect water pipes made from these materials.

Products made of polypropylene

Polypropylene pipe is the most popular material for plumbing. This is due to the presence of some advantageous points: reasonable price, high strength and long service life. Therefore, learning how to connect all types of plastic pipes should start with this type.

Polypropylene pipes are connected by welding with the obligatory use of couplings, angles, tees and other fitting elements. When connecting polypropylene pipes for water supply, you need to purchase pipes and fittings from the same manufacturer. Otherwise, even strict adherence to welding technology cannot guarantee complete tightness and quality.

To connect polypropylene water pipes with your own hands, you need to have the following tools on hand:

Special soldering iron.
This is simply a welding device with a set of special attachments that allows you to connect pipes of different sections. In this case, the nozzle for each pipe is selected individually in accordance with its cross-section.
Cleaning up. This tool is used to cut off the reinforcing layer at the ends of the pipes. Stripping is used only for multilayer reinforced pipe products.
Pipe cutter. By its name you can tell that the device helps cut polypropylene pipes.
A tape measure, pencil or marker may also be needed in the process of joining polypropylene pipe products.

Installation of a water supply system made of polypropylene pipes is carried out as follows:

Turn on and warm up the welding machine. The device must go through three phases: heating to a certain temperature, switching off, and reheating. The operating mode can be monitored by a light indicator (read also: “Types of welding PVC pipes, advantages and disadvantages of methods”).
While the soldering iron is heating, the reinforcing layer is stripped in the place where the fitting will be welded.
Dust and dirt are cleaned from the surface of the elements to be joined and wet areas are wiped well. Please remember that failure to follow these steps may result in a weak connection.
The end of one pipe and the connecting element are inserted into the heating nozzle and kept for a certain period of time. The heating time must be strictly controlled, since holding it for a long time leads to deformation of the elements, and insufficient heating reduces the strength of the connection of plastic water pipes. Therefore, each welding machine is accompanied by a special table, which indicates the heating time of parts having a certain diameter.
The heated elements are pulled out of the nozzles and quickly connected. The strength of the connection also depends on the speed of action at this stage, so the process must be performed quickly but carefully. The pipe is inserted into the fitting until it stops, but it should not be deformed. The connected parts should be held until the plastic has completely cooled.
In a similar way, all elements of the water supply system are connected. To avoid damage to the material, you need to perform actions on unnecessary pipe scraps. The process of welding polypropylene pipes is quite complex, but after a few trial steps you can start working on your own.

Joining of metal-plastic pipes

You can also do the connection of metal-plastic pipe products yourself using one of three methods:

Connecting using compression fittings involves performing the following actions: the end of the pipe is put on the collet, secured with a compression ring and compressed with a clamping nut.
Connecting with crimp fittings involves compressing the ring at the end of the fitting using a special press.
Docking with push fittings is a new joining method that does not require any tools.
This method may be the answer to the question of how to connect plastic pipes without soldering.

Regardless of the chosen method of connecting metal-plastic pipes, the tools should still be prepared. In particular, you will need a pipe cutter, which can be replaced with a regular mounting knife, and a calibrator, which can be any cylindrical object of a certain diameter.

The most popular is the connection of metal-plastic pipes using compression fittings, which involves the following steps:

First, the pipes are cut using a knife or pipe cutter, ensuring a right angle to the cutting line.
Before connecting the pipes, the cut ends are processed, that is, the diameter is calibrated and chamfered, using a calibrator in both cases.
The nut is removed from the fitting and placed on the end of the pipe, followed by a compression ring.
Now the collet is inserted into the end of the pipe, having first checked the presence of rubber O-rings.
Slide the clamping ring onto the collet and tighten the nut on the fitting. At the same time, you should not allow the nut to be over-tightened, as this leads to damage to the rubber seals (read also: “What and how to connect PVC pipes- optimal connection methods").

All water supply elements are connected in a similar way. Such installation is characterized by one advantage: a minimal set of tools for work, which any owner has at hand. In addition, this is the only option that allows you to get a detachable connection, which is necessary in some situations.

Compression fittings for water pipes

The connection using compression fittings is carried out in the same order, only the compression ring and nut are replaced with a ferrule ring. A manual or electric press is used to compress it.

Push fittings make it possible to connect metal-plastic pipes much faster than previous methods. To complete the work, it is enough to insert the prepared end of the pipe into the connecting piece, and all actions are performed without much effort.

When water is supplied to the assembled system, the fitting wedge is pushed out and clamped, thereby preventing water leakage. This method does not require special tools or wrenches, and the installation itself is several times faster. Read also: “How to install plastic pipes - basic installation rules.”

Push fittings can be used to connect pipes made of metal-plastic and cross-linked polyethylene.

The connection using any of the listed methods is sealed and reliable, so you need to choose depending on the available tools and financial capabilities.

Connection of polyethylene pipes

Polyethylene pipes can be connected using one of the following options:

Using compression fittings.
Welding using an electric coupling.

The connection with compression fittings is carried out by analogy with metal-plastic pipes, but in a certain sequence:

The pipe is cut and chamfered.
A clamp nut is placed on the pipe.
It is followed by a collet.
Next, put on the thrust and sealing rings in turn.
The pipe is inserted into the fitting body, all parts are moved to the edge and the nut is tightened.

This method is most often used when assembling household irrigation systems in country houses or on a summer cottage.

The connection of metal-plastic pipes in household water supply systems is carried out using electrofusion welding. Therefore, to perform the work you need to have a special welding device and an electric coupling with a diameter in accordance with the cross-section of the elements being connected.

The welding procedure involves performing the following steps:

Preparation of the surface of the elements to be joined. To do this, use a special scraper to remove the top layer of pipe products and degrease the cleaned area.
The ends of the elements to be connected are inserted into the electric coupling, and the joint should be located exactly in its middle.
The electrofusion coupling is connected to the welding machine and the coils inside it begin to heat up. As a result, the polyethylene begins to melt and welding of the edges of the pipe elements occurs.

A machine for this type of welding has a very high price, so if it is not intended to be used further, it is better to rent the device for a few days rather than spend a large amount for its one-time use.

How to connect PVC pipes

Pipe products made of polyvinyl chloride are connected using a special adhesive composition. However, it is very difficult to call it glue, since when the surfaces being joined are treated with this substance, the plastic melts and the edges are welded and not glued together. In other words, pipes are soldered without a soldering iron.

The process of connecting polyvinyl chloride pipes is as follows:

First, the edges of the pipes to be connected are cleaned of dust and dirt and dried well.
Then the ends are chamfered. This action must be performed so that the adhesive composition is not scraped off when connecting the elements.
Next, one end of the pipe is inserted into the fitting to measure its depth. Make a corresponding mark on the pipe with a pencil or marker.
The end of the pipe is treated with adhesive to the mark using a brush. At the same time, we should not forget that you cannot leave the glue on the surface for more than 25 seconds.
The elements are connected and slightly rotated to evenly distribute the composition over the entire surface. The glue should dry naturally without any external influences. The drying time of the adhesive composition may be affected by air temperature and other factors.

Based on everything said above, we can conclude that in most cases, connecting plastic pipes can be done with your own hands, without having special devices at hand and without possessing special knowledge and skills. The main condition is strict adherence to technology. It is also important to listen to the advice of professionals. This will help install the water supply without unnecessary material costs.

A significant increase in the replacement of obsolete water supply networks has led to the emergence of a leading material such as polypropylene pipes. Therefore, today we’ll talk about how to do this work, what are the advantages of communications made from such material.

Advantages of polypropylene pipes and their scope of application

First of all, you need to know thanks to what qualities polypropylene pipes could so quickly become the most popular material for laying water supply and heating systems.

Advantages of polypropylene pipes:

Polypropylene pipes are highly resistant to corrosion processes. In addition, there is no deposition of mineral salts on the inner walls of the pipes, due to which the cross-section of the pipeline does not change during the entire period of operation.
The guaranteed service life of the pipes is 50 years (subject to operating conditions, temperature and pressure).
Polypropylene pipes can be operated at a liquid pressure of up to 25 atmospheres, the operating temperature is 95, and the maximum permissible (for a short time) reaches 110 degrees.
This material is quite resistant to various chemicals.
An important, and in some cases, the main role is played by the relatively low price and ease of installation of lines made of polypropylene pipes.

The scope of application of such pipes is quite wide; they are used for laying the following pipelines:

A prerequisite for the use of polypropylene in these areas is strict adherence to soldering (welding) technology, and for this you need to know how to properly solder plastic pipes and what tool is used for this.

Tool for soldering polypropylene pipes

First of all, you should decide on the choice of tool that is used for soldering polypropylene pipes. To carry out work at the household level, it is enough to purchase an inexpensive minimum set of equipment, which includes:

Welding machine (soldering iron). The main task of this tool is to heat the surfaces of the elements being connected to a temperature of 260 degrees. It is under these conditions that the diffusion welding process is possible, which results in a permanent connection, which in its properties is not inferior to the material of the main pipe.

Before choosing a soldering iron for plastic pipes, you need to determine its main scope of application. For domestic use, models with a power of 900-1200 W are sufficient; for professional purposes, it is worth purchasing more powerful equipment, the cost of which is much more expensive.

When choosing, you should pay attention to the following design features of the tool:

It is these design features of the soldering iron that will determine the ease of working with it and its durability.

Nozzles for soldering pipes. Inexpensive tool kits usually include 3-4 attachments for working with pipes of various diameters. If necessary, such attachments can be purchased separately. The main feature of such elements is the high-quality non-stick coating. Typically, Teflon is used for these purposes; on professional tools, a higher-quality layer of this material is used, which practically prevents polypropylene from sticking during the soldering process.

Special plastic scissors are used to cut polypropylene pipes. They are distinguished by a reinforced design that allows cutting even reinforced pipes. Such a tool is included in any minimum kit for soldering polypropylene pipes.

To work with reinforced pipes, you also need a device that allows you to remove a chamfer from the workpiece along with a layer of aluminum foil. It is not possible to solder reinforced pipes without removing this layer. Of course, you can remove the reinforcement with a simple knife, but with such a device the operation is performed faster and with better quality. Unfortunately, most tool kits do not have such a device, so you need to take care of purchasing it separately.

Rules for soldering polypropylene pipes

Before soldering plastic pipes made of polypropylene, it is necessary to perform a number of preparatory operations:

In general, the procedure for soldering polypropylene pipes is not complicated. The main thing is to respect the dimensions and maintain the temperature treatment time. Then the resulting joint will last quite a long time.
