One-piece coupling with external thread. Coupling combined demountable with an American external thread: device and scope, installation steps. Wide range of products

For a simple connection of the key elements of the water supply system (faucets, boilers, radiators and other connection points), the threaded connection method is most widely used.

In systems made of polypropylene pipes, a water consumer or another element of the system can be connected to the pipe, for example, through couplings combined with external thread . Such a coupling can have the following thread diameter: 1/2, 3/4 inch or 1 inch - and connect to PP-R pipes with a diameter of 16 to 32 mm. Other sizing options are also possible.

NPO "Stroypolimer" guarantees the correct operation of the elements of the water supply system for one year under proper operating conditions. The normal service life of the offered PP-R elements reaches 50 years. All products have quality certificates.

To clarify the conditions of purchase (prices, volumes, dimensions, weight of goods, etc.), you can call the multi-channel telephone number indicated on the site.

Recently, such an element as a clutch is of particular relevance among most modern people. This connecting element is considered almost indispensable for all kinds of installation work. The Male Threaded Coupling is designed for special applications where it is necessary to match different types pipeline. Elements that have an external thread are used in pipelines for hot or cold water supply. Most often they are used in the case when it is necessary to embed:

• tap;
• communication node;
• special measuring device.

Manufacturers guarantee a ten-year service life of a connection using an American HP coupling if the following conditions are met:

• the pressure of the transported liquid does not exceed 2 MPa;
• coolant temperature is not more than 80 ºС;
• the joint on one side is made by soldering, on the other - by threading;
• fluid in the line is chemically neutral.

The fittings presented in our catalog are no less relevant when it is necessary to connect polypropylene or steel pipes. In the existing catalog you can find products in a full range of diameters of polypropylene or steel elements. If you are interested in products that have an external thread and you want to buy them in Moscow, then our specialists will help you with the selection and organization of prompt delivery.

Wide range of products

The detachable American coupling presented in the catalog is inexpensive. Because of what, if necessary, any consumer will be able to pick up goods for a heating radiator. The presented American split coupling has a long service life and can be used in various fields. If you need to buy a clutch detachable american, then contacted the address, on our website a large assortment of these fittings for different pipe diameters is presented.

When mounting any structure, it is often necessary to connect some elements. Sometimes it is simply impossible to do without it.

There will always be elements for connection, but how to connect them is a matter that requires a very careful approach.

If the choice of nails, bolts, screws does not create problems, then with the elements for connecting pipe-rolling materials, everything is a little more complicated.

Such a connecting element for pipe-rolling materials as a coupling is very popular. The choice of materials of this type is quite large, but the coupling connection with an external thread deserves special attention.

The coupling connection is easy. In this case, two blanks are simply twisted into a coupling. If this is the primary laying of the pipeline, then the work goes without difficulty.

But, during the use of the network, it is necessary to partially or completely dismantle the structure. For such cases, a connecting element was provided, which is called -.

A bit of history

The biography of this fastening option has no beginning, but it is assumed that the Americans were involved in its occurrence.

"American" is a coupling having a union nut.

Also, this coupling has a shoulder-stop and a nut with the corresponding part for it.

When working with this fastener, you do not need to turn anything other than the nut. You can disassemble the arranged connection as much as you like. With such actions, it is not necessary to disassemble all other connections. It follows from this that the time and money spent on work can be significantly saved.

Design

Couplings combined with external thread occupy an undeniable leading position in terms of frequency of use, and they are simple and reliable.

The cross section of the device looks like the figure. This mechanism is a metal part - a bookmark.

The outer layer of this mechanism is made of polypropylene, it serves to cover the metal base. It forms a socket on the other side of the mechanism for soldering with other elements of the network.

Connection

This is a pretty simple job. Her order is:

1. First, blanks are prepared, threads are cut into them for seven turns.
2. A joint is selected where two fittings are threaded from the inside.
3. A coupling with an external thread is mounted on the thread of one workpiece, having previously applied a sealing material to it.
4. A union nut is put on a fitting with a shoulder, and screwed onto the next workpiece with sealing material.
5. The final step is to connect the union nut to the threads of the corresponding fitting.

Now the joint is ready. All work with this mechanism was carried out using wrench, which twist the details. The rest of the pipeline at the same time remains motionless.

Manufacturing materials

These connecting elements are made of the following materials:

• cast iron;
• stainless steel;
• steel.

The cost of the product depends on the material used. The operation characteristics of the mechanism are also dependent on it:

• type of fluids that pass through the line;
• possible temperature standards;
• pressure indicators.

The range of options offered is so large that it makes it easy to choose them for any need.

Most often, such mechanisms are coated with nickel. It serves as protection against external influence of factors and gives the product a presentable appearance.

Technical features

The quality of the materials from which the combined split coupling with external thread is made allow the main working parts to serve for a long time, subject to the conditions of use.

The manufacturers claim that the collapsible combined "American" will last ten years, if the following conditions are met:

• in the line, the fluid pressure should not be higher than 2.0 MPa;
• the temperature of the heat carrier should be no more than 80 degrees;
• the joint must be made by threading or polypropylene soldering;
• there must be no aggressive substances in the line.

Key for such device

It would seem that such a device does not represent anything complicated.

But this mechanism has its own hidden secret that you should know.

The whole point is that the union nut is easy to operate with a simple open-end wrench.

And they are mounted with an internal key. It is a hexagon or a cylinder that has selections for hooks, it is a little more difficult, but more reliable.

Use in plumbing

The universal joint obtained using the "American" has become the reason for the great popularity of this mechanism.

In many situations, it turns out to be simply irreplaceable, and often becomes an integral part of some types of equipment, for example:

• tap;
• measuring device;
• a complex switching unit in a hot water supply system.

The combined "American" with an external thread allows you to make a sealed and durable joint.
