The product is made of high-quality brass, which has anti-corrosion properties That is, mounting it, you can not worry about the fact that the fitting will rust during operation Fittings are manufactured using the hot stamping method For this purpose masters use special bar blanks made of brass

Choosing this position for your home, office or any other industrial building, you can not worry about the fact that it will not fit the size After all, everything is optimized to the smallest detail In order to make the connection more reliable, the production increased the number of turns of the thread Each fitting is additionally coated with a thick layer of Nickel, which extends its durability As a connecting element, you can use anything from the company's huge product range On the packaging you can find all the data that is necessary for installation and operation

 Types and scope of brass fittings

 At the moment, there are quite a large number of connecting elements used for connecting pipes Among them, the most common are fittings made of brass Thanks to their use, even pipes made of different materials can be connected

 In addition, the use of brass fittings is completely safe And the structures themselves are quite strong If you follow all the current requirements for the operation of fittings, their service life can be up to 10 years, and sometimes more At the same time, their technical characteristics will remain almost unchanged

 Distinctive characteristics of fittings

 From the point of view of chemical composition, brass is an alloy of copper and other elements, the main of which is zinc In addition to these two components other chemical elements can be added to brass in small amounts Their main purpose is to improve the technical parameters of brass as a joint The concentration of an element is indicated on the product label, so you can find it out without any extra effort

 Technical parameters of any product, including brass fittings, are determined based on their chemical composition In this regard, fittings made of brass are characterized by the highest strength In addition, they are quite easy to process – they are easily cut, deformed, welded and other processes Since brass is a fairly fluid compound, a variety of products can be made from it in molten form (even small sizes) And this compound has a rather attractive color, similar to Golden  

 The material that is obtained by mixing copper and zinc has characteristics that distinguish it from both the first and second elements In this case, the final substance is more durable Therefore, it can be used in non-standard conditions In addition, mixing copper and zinc allows you to get a more economical, from a financial point of view, element Moreover, even a few years after the start of operation, the main technical characteristics of brass remain unchanged And if you add additional chemical elements to brass, it will allow you to make an almost ideal product for connecting various types of pipes

 A peculiar disadvantage of brass is that it is less protected from corrosion Compared to pure elements (copper and zinc) However, this disadvantage can be eliminated by applying a special protective coating to the surface of the product Compared with copper, brass has a slightly lower thermal conductivity, but this characteristic can hardly be considered negative, since it allows you to prevent the appearance of burns when in contact with the product Well, another confirmation that brass is one of the best materials is the highest popularity of using brass fittings as elements for connecting various types of pipes

 Of course, the characteristics of brass fittings are much worse than those of stainless steel fittings Those have a much longer service life and more reliable protective qualities Moreover, it is almost impossible to use brass fittings at high pressure But if you compare brass and other materials in terms of economy, in this regard, the use of brass products seems more rational

 Another absolute advantage of brass is that this connection is quite soft Therefore, if you use brass fittings to connect the pipes, then their installation will not require special efforts

 Classification of brass fittings

 The number of types of brass fittings is quite large Most often they are made in the form of nipples, couplings, tees and other connecting elements They are used not only in the household sphere, but also in industrial production

 Brass fittings are often used to connect pipes of different diameters At first glance, it may seem that it is almost impossible to connect such pipes But there are so many forms of fittings today that they allow you to use them when connecting even pipes made of different materials In addition, they are often used for branching pipes, as well as for equipping a specific section of the pipeline with an additional branch

 When installed on a pipeline, various types of fittings are used, each of which has its own characteristics and performs a specific function

 Taps

 By using this type of fittings, you can change the direction angle when laying the pipeline in the range from 45 to 120 degrees

 Tees

 With the help of tees, you can connect three pipes, one of which is located at right angles to the other This way you can use this type of fitting to branch a pipeline or connect multiple pipelines

 Cross

 This type of fitting is designed to connect four pipes, each of which is at right angles to the others The name of this form comes from the fact that when connecting the pipeline structure as if intersects two directions of pipes

 Straight and transition couplings

 This type of fitting connects 2 pipes running in a straight line Straight couplings are designed to connect pipes of the same diameter The use of adapter couplings allows you to connect pipes made of different materials, as well as pipes of different diameters

 Sleeves

 This type of fitting is used, rather, not for connecting, but for building up one of the pipes Externally, such a fitting is on one side a pipe of small length and the same diameter as the main one On the other side of this fitting there is a thread for connecting the second pipe

 «American»

 This fitting is similar in its structure and purpose to sgons The only difference is that in this case, at one end of the fitting there is a cap nut, with which the connection is provided

 Plugs

 This type of fitting is designed for hermetic sealing of pipe ends That is, with the help of a plug, the pipes are not connected, but as it were closed, thereby preventing the movement of liquid through them

 Fitting

 This type of connecting elements from the point of view of appearance is a bushing, at one end of which there is a thread It is used, as a rule, in water supply and other similar networks

 Nipple

 The nipple is also similar in structure to a bushing Its difference from the fitting is that that the nipple at both ends= has a thread with which they are connected to the pipelines

 Overlay threaded

 This type of connecting elements is usually it is used in those systems where there is a need to use various types of measuring devices Such devices are connected to the pipeline just with the help of a footer The design feature of this element is that at one end of it there is an internal thread, and at the other – an external one

 As a rule, most types of connecting elements made of brass can be used at a liquid temperature in the system up to 2000 degrees But regarding the pressure, we can say that its limit is 20 bar in the absence of steam, or 10 bar if steam is generated during the operation of the system

 Types of exterior coatings

 As previously noted, to prevent the appearance of corrosion on the surface of fittings, a special protective coating is applied to their outer surface It is usually based on Nickel or chromium Applying this coating not only performs a protective function, but also allows you to make the appearance of finished products more attractive Thanks to the technology of applying these coatings, products become more durable and reliable Moreover, it is equally applied to fittings with a thread, and in its absence

 Any coating that is applied to brass fittings It can be matte or shiny Each of them has its own advantages For example, the advantages of a shiny coating can be considered that it allows you to make the fitting as a result more solid, and there are no irregularities on its surface In favor of the matte coating is that in terms of hardness, it is softer, but it is quite simple to process various types of substances Chrome-coated fittings are equally successfully used for connecting pipes made of almost any metal It doesn't matter if it's copper, iron, cast iron or something else – any pipe can be easily connected using brass fittings Thanks to the chrome coating, they are practically not exposed to aggressive environments, which is another undoubted advantage

 Nickel coating can cause small irregularities that are typical for certain types of fittings But meanwhile, the use of Nickel as a coating makes these products harder The main advantage of the Nickel coating is that it protects the zinc from indentation For unknown reasons, the Nickel applied on the products black in color, slightly loses its characteristics Nevertheless, Nickel-plated fittings continue to be very popular

 Certain requirements for brass fittings relate to the thickness of the coating:

  - chrome – from 0.327 to 1.47 microns

  - Nickel – from 12.6 to 15.3 microns

Features of split connections

 On the basis of whether the pipes to be connected are detachable or non-removable, the types of fittings that are used to connect them also differ In particular, threaded fittings are the most suitable for split pipes They are most often used for connecting pipes in the household sphere that have a relatively small diameter

 To properly connect such a fitting to the pipe, you need to make an inch thread on it The main parameters of such a thread coincide with the diameter of the pipe itself For example, if the thread on the fitting is 32 mm, then the pipe diameter should not be greater than this value

 All threaded fittings have an external or internal thread In addition, they also produce fittings of a combined plan At one end of them, the thread is external, and at the other - internal As for the thread on the pipe that connects this fitting, it is distinguished by a steeper profile Compared to conventional thread This makes the connection more reliable as a result Brass is used as a threaded element in certain types of fittings, and the main part of the product is made of polymer material

 To make the connection more reliable, when tightening the fitting (more precisely, the nuts on it), a regular key is used, as well as auxiliary elements – FUM tape, paste, and other substances and objects that are available to the person who installs the fittings
