Connecting polypropylene pipes without welding. Connecting pipelines made of polypropylene pipes Connecting polypropylene water pipes with fittings

Most often, so-called cold welding is used for this. This technology involves the use adhesive composition special purpose and fittings.

Advantages of using pipe connections without hot soldering

If you are thinking about how to connect a polypropylene pipe to a polypropylene pipe, then you can use a method that involves the use of special fittings. This technique has many advantages, among them especially the increased efficiency of installation of drainage and water supply systems, and the reduction of the possibility of leaks that can occur during butt welding or during a chemical connection. Among other things, the described technology is less labor-intensive and also requires less energy consumption. Among other things, it is associated with lower material consumption. they are quite cheap. Using fittings and glue, you can connect pipes of various diameters, which range from 6 to 400 millimeters.

Comparison of cold soldering with mechanical and welded joints

Before connecting a polypropylene pipe to a polypropylene pipe, you should consider all the advantages of the cold soldering method. Thus, this technique, with low material consumption, speed and quality of work performed, is not inferior to traditional welding. This gluing technology does not require the use of special equipment, which greatly simplifies manipulations. You don’t have to use a special machine designed for welding, which consumes quite an impressive amount of electricity during operation. Due to this, it is possible to reduce costs installation work. If you are faced with the task of how to connect a polypropylene pipe to a polypropylene pipe, then it is worth comparing the mechanical mating of elements using fittings. The latter technology is not so energy-intensive, but more material-intensive. This is due to the need to purchase additional fittings, which increases the cost of work.

Features of connection using fittings and glue

If you do not know how to connect a polypropylene pipe to a polypropylene pipe, then it is important to familiarize yourself with the technology. To do this, you will need to use glue, which is intended for connecting pipes to parts such as fittings. The latter are most often made from chlorinated polyvinyl chloride. After application, the glue begins to dissolve the surfaces of the parts by 1/3 of the thickness. This makes it possible to implement diffusion cold welding. This process is affected by air temperature and humidity. Before connecting polypropylene pipes using cold welding and fittings, you must ensure that the temperature environment ranges from 5 to 35 degrees. If there is a need to carry out installation work at temperatures below zero, then you should purchase frost-resistant glue, which can be applied until the thermometer drops to -18 degrees. If the work is carried out in hot weather, then gluing must be done in much more short time, which will eliminate the possibility of the composition drying out before the manipulations are completed. Before connecting polypropylene pipes using the described technology, you need to make sure that the glue has a uniform consistency, sufficient fluidity and does not have foreign inclusions.

During breaks between work, the container with the adhesive composition must be closed as tightly as possible, which will prevent the evaporation of volatile active components.

Technology for connecting pipes using fittings and glue

If you decide to use the cold connection method, then you need to use the technology described below. At the first stage, you need to cut off part of the pipe in such a way that you can obtain an element of the required length. For this purpose it is recommended to use a pipe cutter, special scissors or a hacksaw, the latter of which has fairly fine teeth.

If you are thinking about the question of how to properly connect polypropylene pipes, then at the next stage the end of the product is chamfered, and it is important to maintain an angle of 15 degrees. In the process of carrying out these manipulations, a chamfer is used; it is important to prevent the formation of burrs. The next step is to thoroughly clean the fitting socket, as well as the pipe, from dust, dirt and moisture.

In order to achieve effective cleaning connecting elements, you need to use cleaners designed for pipes made of CPVC. With the help of this composition it will be possible to prepare the surfaces well enough for further gluing.

Nuances of the work

If you are faced with the task of how to connect polypropylene pipes without a soldering iron, then at the next stage you can apply glue. In this case, you need to use a brush, carefully distributing the composition over the surface of the socket and pipe. Elements are inserted into each other to uniform distribution composition, you need to rotate the fitting 90 degrees relative to the pipe. The parts are fixed for 30 seconds, during which time they should not be rotated again. It is important to complete the entire process within 1 minute. If you are thinking about how to connect polypropylene pipes without soldering, then after gluing is completed, you need to check the presence of a bead, which is a uniform adhesive layer located around the circumference. You may have to get rid of excess glue using a soft rag.

Why is it worth using the cold method of joining plastic pipes?

Before connecting polypropylene pipes with fittings, you need to weigh all the positive negative sides other technologies. If we are talking about an adhesive connection, which was described above, then it is worth highlighting the advantages that it is possible to carry out high-quality installation pipes even in places where access is particularly difficult. The master will not have to use additional expensive equipment that can consume during operation a large number of electricity. It is possible to carry out the entire process independently, without resorting to the help of professional companies. In the process of gluing parts, a monolithic type structure is formed, which ensures the tightness of the joint. If you decide to use adhesive cold welding, then, unlike conventional welding, inner surface the product will not form sagging, which can narrow the lumen and contribute to the settling of solid particles.

Conclusion

If you keep the connection polypropylene pipes between themselves, observing the simple rules and recommendations described above, then leaks and sagging of the pipeline will be excluded. The service life of a pipeline installed using this method can reach 50 years.

Correctly performed connection of polypropylene pipes guarantees durable and very reliable communications that do not rust and have a number of other advantages.

We are interested in tubular products that are characterized by low weight, simplicity machining and installation, as well as at a relatively low cost, they are connected in detachable and permanent ways. The latter refers to welding performed using one of two technologies: butt welding or the coupling (socket) method.

Butt welding is ideal for polypropylene products with a cross-section of more than 6.3 cm. In this case, the thickness of their walls must be at least 4 mm. The procedure is carried out by a stationary welding unit, which provides very precise installation with different geometric parameters. Their ends are trimmed before the operation begins in order to obtain completely parallel surfaces. The butt welding machine has a special disk - it functions as a heating device.

Butt welding of polypropylene products

Also, when carrying out such a procedure, in most cases it is necessary to use centering elements. They give the polypropylene products being connected the necessary alignment. Socket welding is recommended for pipes with a cross-section of less than 6.3 cm. This type of connection requires the mandatory use of couplings and fittings. Without them, the procedure is not performed. Fittings that have special sockets are used to form various docking units (including threaded ones). And the coupling is installed between two pipes to be welded.

For sleeve welding of pipes with a cross-section of up to 4 cm, it is allowed to use a manual unit. It is equipped with nozzles (elements for heating), which are made in the form of a mandrel (it is necessary for melting the inner part of the bell) and a sleeve (melting the outer part).

Heating elements are usually coated with Teflon. This non-stick composition perfectly protects the nozzles from failure during operation. After completing each individual welding operation Hot attachments should be cleaned.For this, scrapers made of wood or coarse rags (for example, tarpaulin) are used. Once the nozzles have completely cooled, it is impossible to remove the layer of molten polypropylene from them. You will simply ruin the expensive Teflon layer.

Let's see how it is necessary to connect the pipe products in question using a welding machine. The scheme of work (it is approximately the same for butt welding and for the procedure using couplings) is as follows:

On welding device mount the required size nozzles and place the device on a flat surface.
Set the welder to the temperature required for welding polypropylene products (it is 260 °C) and wait about a quarter of an hour (during this time the nozzles heat up to the specified level).
Using a pipe cutter or scissors, cut the polypropylene product at a right angle, clean the pipes from dirt and dust, and remove grease stains from them (with soapy water or regular alcohol).
Place a mark on the pipe (it shows the depth of the socket; in addition, you need to add another 2 mm to this value).
Insert the pipe into a smooth sleeve (focusing on the mark you made earlier), and pull the socket onto the mandrel.
You wait until the structure warms up (the heating time is indicated in the instructions for the welding machine), remove the heated elements from the welder and connect them (it is very important to ensure the alignment of the coupling and the pipe product).
Wait for the structure to cool down. During this period, it is prohibited to deform (bend, turn) the pipes.

Welding machine for connecting pipe products

The operation is completed. You have received a reliable and durable welded joint. If there is a need to arrange wiring from the main pipeline, you need to use special welded saddles. Mount them like this:

For 30 seconds, use the welding unit to heat the surface (outer) of the main pipe and the saddle for welding (the operations are performed simultaneously).
Press (without turning) the saddle against the pipe and maintain the load for about half a minute.
Leave the connection for 10 minutes.

Then use a twist drill to drill through the wall of the polypropylene pipe and the bottom of the saddle to make the required branch. It is advisable to use on at this stage a special washer (called a setting washer) to accurately maintain the drilling depth.

The above methods for joining polypropylene products require the use of welding machines and heating plates. Not every House master has similar devices. But there is no point in buying a welder and attachments for it for the sake of installing one pipeline.

In such situations, it is possible to make detachable pipe connections without welding. The operation is performed using two methods: compression-type fittings or cold welding composition. The second technology is suitable exclusively for those through which cold water. Cold welding Apply to the products to be joined and press them firmly against each other for 5–10 seconds. You can give the connection additional tightness by coating the joint with silicone sealant or by wrapping it with Teflon tape.

Detachable pipe connection without welding

If you decide to create polypropylene pipeline When connecting its elements with fittings, you will need a crimp wrench. It is easy to purchase at any hardware store. But most often such a key is included in the fitting kit. You don't even have to buy it separately. To perform work using this method, you will need the following details:

crosses, tees;
Ball Valves;
couplings;
adapters;
saddles for branches;
plugs;
squares with nuts (cap nuts).

Working with fittings is simple - install the required element and crimp it using a wrench. But at the same time, be prepared for the fact that the work on connecting the pipes will take you a very long time. It is necessary to carefully compress each structural element, check the quality of the resulting connection, and additionally seal it. It is for this reason that systems made from polypropylene products are usually assembled by welding.

True, in some cases it is impossible to do without fittings. For example, if you need to connect metal and polypropylene products. In such situations, special fittings will be required - transitional ones. On one side they have a thread for entry steel pipe, on the other - a solder coupling (a product made of propylene is placed in it).

You can also assemble metal and polypropylene pipes using: a fitting with a special union-type nut; couplings and American ones (in this case a union nut is also used). Choose the connection method that suits you!

Connection of polyethylene pipes
How to connect PVC pipes

To install your own water supply from plastic pipes, you don’t 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 its own 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 plumbing system made of polypropylene pipes is performed as follows:

Turn on and warm up the welding machine. The device must go through three phases: heating to certain temperature, shutdown, reheat. 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

Compound metal-plastic pipes You can also make these 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. In this case, you should not allow the nut to be over-tightened, as this will lead to damage. rubber seals(read also: “What and how to connect PVC pipes – optimal ways connections").

All water supply elements are connected in a similar way. Similar installation 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 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 than to 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.

Significant increase in the replacement of obsolete water supply networks led to the emergence of such material as polypropylene pipes into a leading position. 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 household use Models with a power of 900-1200 W are quite 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 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 quality non-stick coating. Typically, Teflon is used for these purposes, professional instrument 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 the layer aluminum foil. It is not possible to solder reinforced pipes without removing this layer. Of course, you can remove reinforcement using a simple knife, but with this 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.

Soldering polypropylene pipes is an operation that sometimes has to be done in own home with your own hands. It is not at all advisable to buy a welding machine specifically for this. Therefore, many are trying to find such instructions, such methods that would save them from expensive purchases. Today we intend to offer a method that is quite applicable at home and does not require any special equipment.

You can get as much information as possible about polypropylene pipes and methods of welding them.

Do-it-yourself soldering of small-diameter propylene pipes

We will talk about pipes that are most often used for wiring inside the house, i.e. about pipes with a diameter of 20 mm. Let's say we need to solder a pipe and an adjacent corner fitting.

Soldering propylene pipes of this diameter can be easily done if there is some safe source of fire at hand, which could be, for example, a miniature gas burner.

According to existing regulations and to ensure the required quality of the connection, the pipe must extend into the fitting by 14 mm. To avoid violation of this standard, it is advisable to measure this distance from the edge of the pipe in advance and put a mark with a pencil.

Having done this, you can begin deep heating of the elements being soldered. The fitting, of course, must be heated from the inside.

The end of the pipe is heated from the outside.

When both parts are thoroughly heated, they can be inserted into each other.

When inserting the pipe, you should be guided by the previously applied pencil mark, which should be exactly along the edge of the fitting.

After this, the completed connection should be cooled without exposing it to any external influences. The cooled joint will be very strong and will in no way be inferior in strength to those connections that are usually made using special welding machines. You can verify this by cutting the soldering area you just made.

As can be seen in the photo above, the junction of the pipe and the fitting is completely monolithic, and such a pipe can be included in the composition without the slightest fear home system water supply

So, if you need to solder polypropylene pipes, you can easily do this work on your own, without purchasing any special tools for this. To do this, just take note of the recommendation we have given.

When installing communication systems, it is necessary to connect individual elements, however, this process can be performed in completely different ways. Special attention The connection of plastic pipes without soldering deserves, because in this case it is possible to do without the use of a special apparatus, the price of which is quite high.

Docking using fittings

With this option, a set of shaped parts is used that makes it possible to combine not only two, but also more elements. Every developer who does not have a soldering machine at his disposal wants to learn how to connect plastic pipes in this way.

Advantages of the method

The low cost of fittings allows you to reduce the cost of connecting communications.
The ease of installation makes it possible for even non-professionals to do the docking.
The ability to use parts in pressurized systems expands the scope of application.

Note! It must be taken into account that this method applicable for elements with a small diameter, and in other situations it is thermally affected joining that is most often used.

Carrying out work

It's time to understand how plastic pipes are connected directly with compression fittings. Tools you will need: sharp knife for cutting elements, a calibrator, as well as manual or automatic pliers for the clamping operation.

First of all, cutting is done components communication system, if required in a particular case. The cut must be made strictly perpendicular to avoid bevels and other flaws. After this, using a calibrator, the ovality at the joint is eliminated.

Next, a special coupling is put on, and the fitting itself with O-rings is inserted inside the pipe. The top is crimped using prepared pliers. In this way, it is possible to join the plastic elements.

However, in some cases you need to know how to connect a plastic pipe to a cast iron pipe. For this, a special adapter is used, the diameter of the sides of which corresponds to the size of the pipes used. During the joining process, it is necessary to remember that the linear expansion coefficients of plastic and cast iron are noticeably different.

Gluing individual elements

In addition to the above option, there are other ways to connect plastic pipes. One of these is the gluing process, when the ends of the component parts are joined using a special chemical composition. During the work, it is possible to ensure sufficient tightness.

The principle of operation of the composition

Adhesive intended for plastic products, usually contains polyvinyl chloride, soluble in methyl ethyl ketone, tetrahydrofuran and cyclohesanone. Special additives are also added to two-component formulations to improve adhesion.

Advantages of the glue method

High-quality grip chemical agent with the surfaces of the elements allows for high tightness.
Availability base material makes it possible to use it to a wide circle consumers.
Invisibility of the joint has a positive effect on the aesthetic perception of the components of the communication system.

Attention! The adhesive used must be stored at a sufficient distance from open flame, as it catches fire easily. In addition, during work it is necessary to protect the skin from contact with the substance.

Application of the composition

You can do the gluing yourself. Work must be carried out at temperatures from +5 to +35 degrees. You need to prepare a brush with natural bristles in advance. In most cases, it comes directly with the adhesive.

Before starting the main steps, it is advisable to assemble the structure without using chemicals in order to perform preliminary fitting. Before applying the substance to mandatory The surface is degreased using solvents.

A thin layer of glue is applied to the prepared surfaces. The plastic product is inserted into the hole until it stops, and rotation or other manipulations must be avoided. The components are held for 15-20 seconds so that the adhesive has time to dry.

Fitting into socket

The presented method is applicable mainly for, since pressure is not created in them. At the ends of the elements used there are special connections for plastic pipes - sockets. With their help, the fixation itself is carried out.

Positive aspects of technology

The relatively high assembly speed guarantees installation in the shortest possible time.
No need to purchase additional components parts helps reduce costs.
Possibility of implementation self-assembly allows you to refuse professional help.

Important! For non-pressure systems, this option can be considered quite airtight, because during installation a rubber gasket is inserted inside, which at the same time makes it possible to compensate for the mismatch of the parts being connected.

Description of the assembly process

After making sure before installation that there is a rubber ring in the socket, you need to clean it of various contaminants, then you will be able to achieve good adhesion. On the smooth edge
