American corner plumbing. Threaded pipe connection - American, their types by assembly type

In any plumbing work, the main indicator is the provision of a hermetic connection. For this, devices such as a fitting, nut, gasket, clamp can be used. But the most high-quality and effective means for a tight connection is American plumbing.

What is it? It is a special nut designed to connect pipes to each other.

An American is a kind of connection of parts in plumbing, invented in America, hence the name. Later, an American coupling and crane were developed.

Types of threaded connections and what an American connection is made of

The thread on an American can be conical or cylindrical. There may also be a difference in the types of fittings. The surface of the fitting can be conical or flat.

Benefits of a conical seal:

To achieve these advantages, precision in the manufacture of fittings is required. In a flat seal situation, this can be slightly neglected. Here they use a flat Teflon gasket-ring.

An American nut can be used more than once, only replacing the old gasket will be enough, which can help protect yourself from buying new plumbing.

For the manufacture of connections, stainless steel, brass, chromium, nickel, cast iron, a combination of metals can be used. The use of these materials can be separately and in an alloy. The most durable will be the design, made with stainless steel elements. However, experts prefer chrome-plated parts, since an American made of this material is characterized by a high level of quality and plasticity. In addition, the reinforced structure does not require the use of a gasket.

Metal and polypropylene in the design will provide high tightness.

The American connection can be made using a variety of stainless steel grades. These are mainly brands such as AISI304, AISI316, AISI321.

The marking includes dimensions (unit inch), steel grade and conditional pressure in PSI.

The outer coating of the American is galvanized nickel, which protects it from corrosive formations and helps to increase the resistance to mechanical wear. This coating is also a decorative finish.

Coupling american

A coupling is a type of fitting used when connecting two pipes or when transferring a pipe with one diameter to a pipe with another.

An American coupling is the same coupling, on one side it is tightly screwed or welded, and on the other it is a collapsible American connection.

Crane American

At the moment, the most successful and common element of valves is a ball valve. There is a wide variety of types of ball valve, for example, decorative, special, having internal and external threads on one side only, American ball valve, etc.

In general, an American faucet allows you to solve one important problem when installing plumbing, it is a replacement for a standard plumbing fixture, which consists of such elements as a long thread, a coupling, a lock nut, a plumb thread. It helps to simplify the task and with a few turns of the wrench to pull off the crane itself and its American.

Also, an American crane is used for the installation of heating radiators. The battery, attached on both sides by an American tap, becomes easily removable. Another plus here is that the water supply can be adjusted by hand, and as a result, the temperature of the heating radiator during operation.

Compared to plastic faucets, the American faucet is able to withstand higher operating temperatures, but they are not designed for extreme temperatures.

The working medium of an American woman can be hot and cold water, as well as a liquid non-aggressive medium transported through a process pipeline. The operating temperature should not be higher than +120 degrees Celsius.

An American corner is simply a necessary element so that you don’t have to pile up a lot of connections.

Like any ball valve, an American crane differs in the type of handle:

The butterfly is placed, as a rule, on cranes with a small section, since such cranes require little effort when turning. And the handle-lever is used for taps with a large section, where more effort is required to turn.

In any plumbing work, a reliable connection is the most important indicator. Ensuring water tightness is very important. For this, various nuts, fittings, gaskets, etc. are used. However, according to statistics, the tool that creates the highest quality and most effective tightness of the connection is American plumbing.

The structure and size of plumbing "American"

By design, an American is classified as a coupling with a union nut. With this element, a direct connection is created, and this simplifies many installation work.

The standard American kit includes a union nut, gasket, pressure fitting and nipple.

When choosing, you need to pay attention to the model, each model has its own parameters. The nut in diameter can be from twenty to sixty millimeters.

Mounting

As mentioned above, an American allows you to create a high-quality and convenient threaded connection quite simply. So, you can do the work of replacing the plumbing element yourself.

An American with an internal thread is used to connect pipes with the same diameter. At the ends of each pipe, seven turns are cut using a special cutting tool (die). Further, there may be several options for connections.

Before directly twisting the American at the end of the pipe, a sealant is placed there clockwise. The first turns should be left without a seal for easy putting on an American. The American is screwed onto the seal with a key. The material can be sealed with improvised means, for example, energy flex, flax, polypropylene tape, etc. The second end of the pipe, after the thread is twisted, is sealed and the second part of the American is wound onto it. So the two pipes are connected.

American mounting tool

When installing a structure using an American, they use wrench. He is the best for this job.

American is a universal connection, without it it is almost impossible to carry out installation work. It is used in the connections of the metering device and fittings to the pipeline of the hot and cold water supply system, in plumbing with threaded couplings, as well as for polypropylene pipes.

Currently, the American is being produced as a separate element or as an addition to certain types of fittings for the pipeline.

Another connection option is:

• thread is cut;
• winding the seal;
• a long thread is wound on the second end of the pipe;
• a lock nut is screwed onto a long thread, then an American;
• a second pipe is installed;
• two parts of an American are connected;
• winding the seal;
• the locknut is tightened close to the American.

Approximately the same principle of connection using an American with an external thread.

The American is installed on the pipeline in a place accessible for inspection in any position, the direction of the liquid does not affect the installation.

In plumbing, an American is always used for such work as replacing a heating radiator, installing a meter for hot and cold water, installing shutoff valves, connecting individual sections of pipes, installing deep filters. This makes the design very convenient for further maintenance.

The American is a universal and indispensable device that is used in domestic and industrial construction of pipelines of various configurations. Almost all craftsmen have to face the need to create a quick-connect connection on the highway to replace its section, insert an insert or clean it. Thanks to this useful invention, plumbers have at their disposal a variety of Americans for plumbing, allowing them to perform work quickly and efficiently.

The “American” connection owes its name to the country where the technology of threaded connection of materials of different sections and compositions was developed. US GOST American thread standard does not match the standards in force in Europe and Asia. But, quite often there is a need to create a single system of pipes and plumbing devices of various origins. In order to adapt their products to the standards of importing countries, American designers came up with a technology for fast and reliable joining of plastic, copper and steel pipes.

American couplings are used to perform the following tasks:

• inserts into the system of tees, taps and other devices;
• replacement of the damaged section of the highway;
• installation without the use of electric and gas welding.

To understand what an American is, it is necessary to consider the design features of this category of fittings, to study their properties, advantages and scope.

What are the types of fittings

The assembly of pipelines for water supply, heating and gas supply involves the presence of many branches, branches and intermediate devices. At the same time, it is necessary to provide connection options for a heated towel rail, toilet tank, radiators and many other devices.

The detachable pipe connection must be tight, strong and durable.

Particular attention is paid to the aesthetic side of the issue. To achieve these goals are used.

Gusset

It is used at the joints of pipeline sections at a certain angle. If earlier adapters were welded into the system, now this need has disappeared. Corner American women have different diameters and degrees of bending. Products are available in 45º, 60º, 90º and 135º bent angles.

The main advantage of such fittings is that the transition from one direction to another is carried out smoothly. Connection with a cap nut provides a tight fit of the joints, optimal pressure on the rubber gaskets. At any time, it is possible to remove the fitting for revision or cleaning of the line.

Coupling

Combined detachable coupling is used to connect straight sections of the highway. American inch thread allows for non-ferrous and ferrous metal.

Despite the seemingly simple device, these fittings are able to ensure the tightness of the joints throughout the entire period of operation of the system. The undoubted advantage of using the coupling is the possibility of its unwinding and removal. The product is reusable, can be used repeatedly without loss of quality characteristics.

Cranes

Experts recommend using a sealing tape when installing an American straight brass coupling to prevent even the slightest possibility of leakage. Cone fittings are usually installed in heating and hot water systems, as these products are resistant to high temperatures.

Flat fittings use a swivel nut on the flange and a flat gasket to ensure a tight seal. It is easy to mount cylindrical inserts; gas wrenches can be used for this. The disadvantage is that the gasket shrinks over time, changes shape and begins to let water through.

It is not recommended to hide such varieties of American women in walls or under decoration. A leak will definitely occur, it's a matter of time.

With threaded fitting

Such a device with an external thread allows you to join polypropylene pipes without the use of welding. In some cases, the distance between the wall and the junction is so small that the issue can only be resolved by installing an American with a threaded fitting. For work it is necessary to use special tools, with a fixed application of effort.

With internal thread

When working with pipelines made of steel and brass, durable and reliable fittings with internal threads are used. The use of plastic in such joints is not recommended.

Previously, the tubes are carved under the American.

For this, there is no need to dismantle or cut off part of the system. After that, no matter how many inches of internal thread, the union nut is screwed onto the pipeline.

materials

American fittings are made from materials that have different strength, resistance to temperature changes and corrosion. Each pipeline has its own characteristics, under which its own version of connections and inserts is selected.

Steel (stainless)

Stainless steel products are characterized by high strength, ease of use and long service life. They do not change their appearance throughout the service.

The cost of steel socket welding fittings is in the middle range, which makes them popular among amateurs and professionals.

Galvanized

They belong to the budget category of goods of this class. The availability of products attracts craftsmen when carrying out large-scale construction work. However, the service life of galvanized fittings is limited. Within a few years, their geometry is broken due to corrosion, destroying black iron. Zinc itself departs from the body of the product in a maximum of a year, exposing unsightly rust.

brass

An overview of the types of couplings for polypropylene pipes allows us to conclude that brass American women meet all the requirements regarding reliability and safety.

The alloy is strong, elastic, resistant to heat and chemically active liquids. The disadvantage is the high cost and discoloration of brass during operation. The appearance of products is improved by chrome plating or powder coating.

Copper

Copper Americans are produced in limited quantities due to low demand and high cost. Fittings made of this metal are in demand only when they are attached to products made of a similar material. Copper is difficult to care for as it darkens and develops a greenish patina.

The metal is subject to electrolytic corrosion, which is impossible to fight.

Plastic

In its pure form, American women are not made only from polypropylene. This plastic does not have sufficient strength to connect pipes and plumbing fixtures. A polymer is used as a base into which metal threaded inserts are fused. As a rule, plastic American women are used in systems where high temperature and pressure are present.

Average price per fitting

The table below shows current offers for today.

Advantages and disadvantages

Having considered the features of American plumbing, answering the question of what it is, you can dwell on the advantages and disadvantages of these devices.

Let's take a look at their benefits first:

1. reliability and strength of docking, absolute tightness of the connection;
2. simplicity and high speed of installation, involving the tightening of one or two nuts;
3. collapsible connection, which can be easily removed and put back;
4. the possibility of joining pipes from materials of different structure;
5. a wide range of products of different configurations with seals included;
6. long service life of the structure assembled using an American.

There are no technical shortcomings in the fittings of this category. The high cost confuses low-income craftsmen, but it is justified by the high quality of the goods. As for changing the color of products made of non-ferrous and ferrous metal, they are installed in technological channels, covered with panels and boxes.

Keys for Americans

• wrench;
• open-end wrench;
• cap key;
• dies for threading;
• internal keys with 6, 12 and 34 edges;
• expansion round wrench.

It is better to buy tools in a set that is cheaper and helps to solve any issues with installing an American.

How to install

Depending on what material you have to work with, various methods of fitting fittings are selected.

At the joints of metal pipes

Steel lines are used to transport hot liquids under high pressure. Threaded connections are used to connect their sections.

First you need to take a die of the desired size and make 7 turns of thread at each joint. After that, the fitting is inserted between the joints, and the union nuts are screwed onto the threads until the required degree of gasket pressure is reached.

In the joints of plastic

Threads are not made on polypropylene pipes, since they are not intended for this. Adapters with metal fragments pressed into them with internal or external threads are welded or glued to the ends of the pipes (depending on the working conditions). And American women are already screwing on these elements.

Plumbing assembly is considered to be of high quality if all connections are sufficiently tight. In practice, this is achieved through the use of various fittings, nuts, gaskets and other connecting elements used in plumbing work. Such elements are quite suitable for effective use, but at the same time, there is a much better solution in the form of a universal nut, known as the "American".

Let's figure out what "American" is and why it has gained such great popularity.

The American plug connection is a kind of nut that finds its application when it becomes necessary to connect two pipes. Previously, spurs were used for this, which are still found today, since their cost is significantly lower compared to the connection of the type in question.

The use of "American women" in plumbing makes it possible to simplify the process of connecting two fixed pipes as much as possible. For example, you need to connect a faucet and soldered wiring. Both in the first and in the second case, the pipes cannot be twisted, and, possibly, the thread is located close to the wall, which excludes the use of the same corner. It is in such situations that the "American" comes to the rescue, providing a connection due to the rotation of the nut, which is part of its design:

• two fittings;
• pad;
• hex nut.

Pipe connection options

The connection of the "American" type is provided due to a certain variability of the connection to the pipe, which involves the use of:

Types of threaded connections

The thread of the "American" can be conical or cylindrical. A similar variability is present in the case of fittings, the connecting surfaces of which differ in the mentioned shapes.

As for the conical seal, it has a certain set of advantages:

• ensuring the tightness of the connection without any gaskets, FUM tape, flax fiber, etc.;
• resistance to various kinds of influences, for example, temperature extremes, which is achieved due to the homogeneity of the material in terms of its chemical composition and physical characteristics;
• preservation of tightness with deviations of the axes of the connected parts up to 5 degrees.

The mentioned advantages in relation to the conical elements of the "American" are achieved due to the high precision of their manufacture, which can be neglected to a certain extent when it comes to flat seals. Here, the use of a gasket in the form of a ring is sufficient to achieve the required tightness even when the surface of the connecting elements is not distinguished by high-precision processing.

In the production of "American women" steel of various grades is used. Although AISI steel under the numerical designations 304, 316 and 321 is more popular. Steel marking also includes an indication of nominal pressure (PSI) and size in inches.

Gusset

For the convenience of organizing turns, an "American" is produced, providing a corner connection. Usually this is in demand when there is no possibility of arranging piping. At the same time, it is possible to save money, since in this case one less connection is established.

Coupling

A coupling is a fitting that provides a connection between pipes or makes it possible to organize a transition from a pipe of one diameter to a pipe of another diameter. The “American” is identical in functionality to a standard coupling, one part of which is screwed, soldered or welded to the pipe, and the other provides for the installation of a collapsible connection.

Crane "American"

Ball valves are the most popular elements of shut-off valves, of course, provided that they are manufactured in accordance with the required level of quality. There is a huge mass of these products, among which there are taps oriented, for example, to some special use or performing decorative functions. At the same time, there is also an “American”, supplemented by a ball valve.

Many people know that this type of crane exists, but only a few have used it in practice. This state of affairs is due to simple ignorance of all the advantages of this product. Meanwhile, with its help, you can replace such an element of plumbing as a squeegee - a part for connecting two pipes, where a long thread is applied on one side, and a short one on the other, which is complemented by a coupling and a lock nut. In the proposed version, everything is much simpler, since it provides for the contraction of the crane and the element in the form of the “American” itself due to the slight use of the wrench. These two parts are self-centering, which facilitates the process of their installation.

Often, the "American" faucet is used when installing heating radiators, which leads to some positive aspects. The connection of these connecting elements makes it easy to dismantle the radiator, and the presence of a tap makes it possible to regulate the water supply, which allows you to influence the temperature in the room.

Like all types of ball valves, the "American" is equipped with two types of handles, where one should be understood as a butterfly, and under the other - a lever. In the first case, these are cranes with a small section, characterized by the absence of the need to apply too much force to turn, and in the second case, cranes with a large section, the operation of which is associated with the application of a greater force.

Assembly

The “Americana” union nut is tightened with a standard open-end wrench or a union version of this type of tool is used. Some try to use a spanner, which is not recommended as it may damage the nickel plating. If there is a decorative coating on the nut, rubber or plastic gaskets should be used, and plywood can also be used.

The installation of "American women" on metal-plastic pipes involves the use of a special tool in the form of an internal key. It is necessary for tightening the press fitting during installation. Typically, such a key is in the form of a cylinder, complemented by two recesses that are necessary for the hooks, but a hexagonal version is also available.

Instead of an internal key, an improvised tool, such as pliers, is often used, which increases the likelihood of damaging the product in question. When one-time work of this plan is supposed, that is, it is necessary to install only one connection of the "American" type, then this approach is justified to a certain extent, but in the case of installing several pipes, you should still take care of buying a special tool.

If you have the skills to work with metal, then you can easily make your own cone wrench of the required size. Tapering is necessary to ensure that it enters the existing recesses. Profile fittings can be used as a material for making a key.

For the "American", the diameters of the internal and external threads of which are defined as 1/2, a key is required in accordance with such dimensions as 12 by 12 mm and 10 by 10 mm. The shape of the key should resemble the letter "G", having a handle length of 150 mm.

Materials for the manufacture of "American"

The production process of "American women" is based on the following types of materials:

• cast iron;
• nickel;
• chromium;
• brass, chosen due to the fact that this material is able to withstand high temperatures of the coolant, reaching 120 ° C;
• stainless steel (ISI304, AISI316, AISI321) ;
• combined, including propylene.

Of the above materials, stainless steel is worth mentioning again, as it provides the ability to produce the most durable "American". Although consumers of these products often prefer copies made of chrome, as this material combines quality and practicality. It also does not require the installation of a gasket for "American" chrome to ensure the tightness of the connection.

If pure steel is used for the production of the type of product in question without special treatment, then after a few years such a product will begin to collapse. Galvanized can withstand about 10 years, and stainless - about 20 years.

Conical or flat?

Conical "American", supplemented with a rubber seal, provide tightness due to internal pressure, in this case, the union nut can even be tightened by hand. As for flat sealing options, it will be necessary to provide the necessary contact pressure.

Mandatory tightness of the connection can be provided by both a conical "American" and a flat one. At the same time, flat ones make it easy to change gaskets, which are not in short supply. And for conical ones, special gaskets are needed, which differ in a non-standard size. In turn, conical ones without gaskets should not be chosen, since in order to create a tight connection, it is necessary to tighten the nut very tightly, which is unacceptable if the pipes, for example, are plastic.

Conclusion

As you can see, an American in plumbing is already an indispensable part. That is why it is so widespread.

American… What is it? This name is a quick-release nut equipped with a thread. The design of the element includes 2 threaded fittings, a union nut and a gasket. An American is often used for pipe installation, as it provides a reliable and tight connection. This is a universal element, very often used during installation work.

The American can be used to install hot and cold water pipes, heating systems, technological structures intended for the transportation of non-aggressive substances.

Connection types

The conical type of fastening, performed by means of an American, has many advantages. In particular, the connection is sealed and reliable. It is resistant to temperature extremes and chemical environments. You can use an American even when the axes of the pipes deviate slightly. Even in this case, the installation will be of high quality and reliable.

A threaded connection is indispensable in cases where instant joining or dismantling of pipes and control parts is required. You can see the types of installation by looking at the photo.

The American nut is good because it can be used several times. To carry out repeated installation work, you only need to purchase a new gasket.

Characteristics

The American has a number of advantages over other fittings. With its help, you can undock the structure without using the rotation method. These elements are made from a variety of materials: polypropylene, stainless steel, cast iron, brass.

For installation using an American, a special key is required. You can either buy it in the store or make it yourself.

There are different sizes of this item. The choice of a particular one depends on the specifics of the work. The most commonly used American sizes are 12 and 34.

Through this element, you can connect both hard and soft lines of structures. The connection is of two types: direct and angular. This factor is very important for comfortable and quick installation.

The corner element allows you to perform installation work in hard-to-reach areas, fasten parts of different types and sizes together. The American makes it easier to repair the system. So, you can quickly dismantle the system without using an additional tool.

The part can be installed on pipes transporting hot and cold water, non-aggressive liquids. In this case, the temperature of the liquids should not be more than 120 degrees. The part is used for mounting elements with a small diameter.

In stores you can find different types of American women: with external and internal threads. The element can be mounted in any position. In this case, it is not required to take into account the direction of transport of the substance in the system.

The connection is made by means of wrenches of open-end and adjustable type. You can also use generic type keys. Pipe gas wrenches cannot be used in work.

The outer surface of the element consists of a nickel galvanic sheath. It is necessary in order for the part to have increased resistance to corrosion and mechanical stress. In addition, this coating also has an aesthetic meaning. With it, the element acquires a pleasing to the eye appearance.

Scope of use

This element is used for a wide range of applications. In particular, it is used for the installation of water supply structures, in heating systems. The excellent consumer qualities of the elements make them suitable for connecting any type of pipe. They are also used for repair work on radiators, and for the installation of water meters, and for the installation of shut-off valves, and for attaching structural parts, and for installing cleaning filters.

The advantages of the American are not only that it can be easily and quickly installed, but also during the further operation of the system. The part facilitates further repair work, dismantling.

Now you know all the necessary information about this irreplaceable part: what it is, where it is used, how the work is done. You can see what it looks like through the photo. You can see them on our website. The photo shows different types of parts, which will allow you to better navigate in the store with the corresponding products.

This is the name of the type of threaded connection of pipes in water supply and hot water systems. With the appearance on the market, the American quickly gained popularity among plumbing professionals due to the ease of installation and the reliability of joining pipeline elements.

If you need to connect pipes - an American is ideal. Indeed, later, when performing repair work, there is no need to dismantle part of the network.

It is impossible to assemble a pipeline from a single pipe. It is necessary to perform rotations and connections of pipeline elements in order to obtain the desired configuration. Fittings have always been used to make joints.

You can also install using a coupling, which in the standard version is a threaded part. When connected, it is screwed onto the threaded part.

The next part is rotated into the clutch and such an operation (especially if all the elements are large) is quite a noticeable inconvenience.

What is an American

• threaded fittings - are attached to one part of the water pipe at the connector point;
• reciprocal branch pipe with a shoulder - is installed on the second end;
• union nut - is installed on a fitting with a flange before it is installed in its location.

Further, when tightening the nut with pressure on the shoulder, the fittings are tightened one to one and these two parts are compressed. Gaskets are used to ensure the tightness of the docking with the help of a coupling. And with a conical joint, it is not required.

If it is necessary to dismantle the section docked by means of an American, it is enough to unscrew the nut, while the mating elements of the pipeline remain motionless.

Types of docking nodes. The number of design solutions for installation corresponds to the number of varieties of molded products.

By type of materials used

It provides for the use of homogeneous elements, primarily in order to avoid electrolytic corrosion, therefore fittings are produced in various designs:

1. . The life cycle of such parts is also limited by the tendency to form lime deposits from water on internal surfaces.
2. Copper- less susceptible to corrosion, they are used only on pipelines made of the same material.
3. brass- the most popular in application, resistant to oxidation, durability is at least 50 years.
4. Polypropylene- in terms of strength characteristics and ease of use, they are increasingly competing with metal products.
5. Polymer– have all the advantages of plastic products. For polypropylene pipes - American is the best type of connection.
6. Combined- are used as adapters when joining pipes made of metal with plastic ones during partial replacement of the pipeline. To make such fittings, a threaded metal part is pressed into a plastic body.

By type of assembly method

In addition to differences in the materials of manufacture, the threaded connection differs in the design of the docking units.

They are threaded, with different threading directions, having internal or external threads on the sides. Samples with a conical joint are also used, with the help of which an American connection is made using a persistent compression ring under the nut.

Video

Such a variety of fittings creates certain difficulties in choosing them for an inexperienced person, but it gives real pleasure to professional performers.

Surface protection method

What are American women by type of protective coating? Steel and cast iron products are coated with a protective nickel or zinc coating to protect against corrosion.

For plastic or stainless analogues, protection is not applied. In this regard, it is recommended to use linings for pipe wrenches or special wrenches with internal engagement of the part.

Docking metal components

Pipelines for various purposes made of metal are still widely used in plumbing. Therefore, the installation of metal pipes is widely used in a variety of options.

For simple joining, threads must be cut at the ends of the elements to be assembled using a standard threading tool. The American is screwed onto the prepared ends, while it is necessary to seal the threads by winding the FUM tape or strands of flax fiber.

The final connection is made by tightening the nut and installing the gasket. If the connector is reused, the gasket must be replaced. The joint is reliable and maintainable. What are Americans for metal components:

• direct connection of metal pipes;
• installation made at right angles, as well as angles of 30 and 45 degrees;
• installation of cantilever water supply elements with a pipe, such as taps, mixers, air vents;
• threaded connection to change to a different diameter;

American allows you to get a sealed joint in pipelines of any configuration.

Docking of plastic components

The connection of the components of pipelines made of composite materials has its own characteristics. Docking of polypropylene pipes is carried out by welding with special equipment. The process is very simple and is carried out on site during the installation process.

Video

Designs are widely used where docking with a polypropylene pipe is made on conical American women, where devices with a sealing ring are used.

The connection of polypropylene pipe-rolls with an American is the most reliable and almost the only way of docking using a detachable coupling, including connecting a heated towel rail.

Several types of connections are used for polypropylene pipes:

• coupling with external thread;
• coupling with internal thread;
• device with simultaneous use of internal and external threads;
• angular, produced with an angle of 30, 45 and 90 degrees for installation in hard-to-reach places.

Installing a towel dryer

The installation of such a device in the bathroom can serve as an example of using a threaded connection for inserting additional equipment. The heated towel rail is connected either to the heating system or to the hot water circuit.

Video

In the second case, you will have to use the services of the DEZ to turn off the DHW riser for several hours, in the first case, you will have to wait until the end of the heating season.

Work can be performed in the following order:

1. Install the dryer in its permanent location.
2. Make a tie-in into the DHW or heating riser with the installation of threaded fittings for inlet and outlet flows.
3. Install corners with ball valves on them.
4. Connect the heated towel rail through plastic pipes. The critical temperature for them is 95 degrees, in neither system such a temperature is applied.
5. On the upper register, install a valve to bleed air from the system, otherwise the air lock may prevent the circulation of the coolant.
6. Check for leaks in the dryer by opening the inlet and outlet ball valves. If there are leaks, you need to re-check the joints by applying additional seals on the threads. Linen tow, fluoroplastic sealing material (FUM) in the form of a tape or cord are suitable for this.
7. The installation of ball valves will allow for repair work without disconnecting the riser. It should be noted that the connection of a heated towel rail with a polypropylene pipe requires a careful attitude, since the clamping ring cannot always be reused due to its deformation.

Connecting the heated towel rail to the riser with a polypropylene pipe using conical American women allows you to avoid the use of pipe benders. This reduces the complexity of work and their adjustment in place.

An example of connecting a heated towel rail through a threaded connection is shown in the figure.

Coupling element dimensions

In domestic plumbing standards, American women are classified as "sleeve connections with a union nut."

Naturally, their size range corresponds to that on the molded elements of water pipes. What types there are depends on the method of docking to the main line or console element.

Video

So, when installing a faucet or faucet, as an element of plumbing, American women are used in sizes from 3/8 to ¾ inch with conical threads. This allows you to make a reliable installation in just a few turns of the nut.

For water pipes, they are used in the range of 10 - 50 mm, the maximum indicator is typical for connection with a heated towel rail.

To connect pipes made of polymers, special couplings are used - conical American women, on which the plastic sheath is literally pulled by the force of the screwed nut through the thrust ring, providing a tightness of the joint several times higher than the pressure in the system.

Pipe dimensions

For an American woman in plumbing, threads can be selected based on the data shown in Table 1.

When using plastic pipes, the properties of the material must be taken into account. such as elasticity, plasticity chemical resistance.

Video

Therefore, for polypropylene products, an American is practically the only connection method that provides high-quality docking. Applying them locally, it is possible to assemble a pipeline of any configuration with a high degree of reliability.

For installation by means of an American, its dimensions must be adequate to the pipes used. For cold and hot water networks, this is an inch or an inch and a quarter; for heating systems in a private house, it is better to use one and a half inch products.
