One of the actively used types of compounds for pipelines with supply or water transportation is the so-called American clutch. The peculiarity of this module is that after mounting the connection can be separated and without negative consequences to connect the pipes again using a special nut on the housing.

A combined American with internal thread connects metal and plastic pipes, and also serves to connect shut-off reinforcement or water heating devices with metal outputs.

Technical characteristics of american

The joining of a combined American with internal thread is performed by two types. The metal part is connected using fittings on the thread, and plastic - with the help of special welding of polypropylene.

The main technical characteristics that are important to consider when mounted an American in the pipeline are as follows:

pressure in the pipe system should not be more than 2.0 MPa;
water temperature is not higher than 80 degrees (resistance to temperature below all-in-mail couplings);
joining with special equipment;
lack of direct influence external environment on the metal part of the coupling.

Specifications Combined American women with internal threads provide long service life of the device. The main criteria for maintaining durability are compliance with the use and quality of materials from which the coupling is made.

Application of combined amenities

American Plumbers call a ready-made quick-release element for connecting 2 pipes.

For these purposes, a widespread was widely used.

The coupling is a cut of a pipe with an internal thread or a wide nut. The coupling is used both to connect the pipes of the same diameter and two pipes of different sizes. In the first case, it is called a coupling, in the second transition.

When installing and fit the compound, it is often necessary to complement the clutch by the Sgon. Sign is a cut of a pipe with an outdoor thread at both ends.

Device

According to its design, American is a combined coupling, a collapsible part consisting of 2 threaded fittings and a cape nut.

American is flat, in this case the tightness of the connection is achieved by the gasket. She is cheap and most compact.

When operating, it may be necessary to pull the nut and replace the exhaust gasket. For these considerations, the connection with the gasket is better not to do hidden.

Another option is a conical American.

Here the gasket is not required, since the polished parts of the fittings made as a cone, when spinning the nuts are tightly pressed to each other.

The deviation along the axis of the mounted pipes should not exceed 5 degrees. They should be carefully checked for hidden defects, as they are usually used in the most important compounds.

Specialist Council: For responsible compounds operating under temperature drops: water heaters, heated towel rails, use a conical American, it is more expensive, but more reliable.

American - a universal and convenient device on a single nut.

To connect the pipes you just need to wrap the cape nut. Fast and convenient installation with the help of american sweating traditional clutches and a split.

With the help of American, the transition to the pipe of another diameter or from another material is solved. With an American you can create an angular connection.

The convenience of the USD connection has led to the fact that some manufacturers of sanitary equipment use it as a mounting element in the design of corporate cranes, metering devices, filters, etc.

American is produced from the following materials:

The last option is a combination of polypropylene with a stainless steel, it is often used when installing plastic risers.

Depending on the thread, outdoor or inner, there are three types of Americans:

coupling carving;
coupling coupling;
carving thread.

There are also versions without threads, to connect to welding.

The choice of a suitable part allows you to do with one connecting node without additional items when installing.

The detachable connection of the American type is available under all running sizes of pipes.

In practice, most often have to deal with 1/2 inches and 3/4 inches.

Benefits

Connecting assembly

An ordinary horny or adjustable key is used to tighten the American naked nut.

You should not use the gas key, it can damage the nickel coating.

If the nut has decorative coatingUse lining. This role can perform suitable pieces of plywood, plastic or rubber.

When installing metal plastic pipes, you will have to use a special tool - an internal key. With it, the press fitting is tightened when installed. Most often there is a form of a cylinder with two recesses for the hook, sometimes hexagon.

Often, instead of a key, pliers or another girlfriend tool are used. However, there is a risk of damaging the product. If you plan to install multiple pipes, it is better to purchase an internal key for American.

Those who can work with metal can make a homemade conical key under the required size.

The taper is necessary to accurately enter the excavation.

For American 1/2, the corresponding key sizes are 12x12 mm and 10x10 mm. The shape of the key M-shaped, the length of the handle is approximately 150 mm.

Mastery of similar homemakes from unnecessary segments of profile fittings.

See the video in which the device and the features of the use of American in Plumbing are explained in detail in Plumbing:

American Delicate 20 x 1/2 "with Internal Thread FV-Plast Czech Republic - This is a fitting connecting the polypropylene tube with plumbing elements. It is soldered by one end to the PPR tube and screws up to another (precipitant nut) on a metal supply to one or another device (heater, expansion tank, etc.) American provides an installation and convenient compound without the need to turn the entire fitting around the pipe. An important part of this connection is a gasket - must be maintained in working condition with all build-disassembly cycles.

FV-Plast fittings are very plastic and durable, are not affected by corrosion and deformation, easily carry high temperatures and chemically aggressive environments. Czech products FV-PLAST occupies a leading position in the polypropylene market, products will last up to 50 years.

Specifications:

Products FV-Plast (Czech Republic) Used for water supply systems, heating, warm floors with coolants in which water and antifreeze are used. The fittings can be melted to mold in the wall, and in the concrete tie of the warm floor.
