Threaded tee for steel pipes. Steel tees. Where to add transitional tees

It is impossible to detect the current connections of any pipeline systems without such elements as a tee, a cut, a coupling, an adapter. All of them belong to a large group of products, such as plumbing robots and those known as fittings. The sanitary threaded tee is used to ensure a tight connection of the storage parts of the pipeline into a single system. This type of device is designed to create a flattened configuration from different pipes. The fitting allows you to create a new pipe without interrupting the central line.

The Santim company promotes to its clients the addition of high-acidity elements of the combined wet trademark STM.

Features of our proposition

Regardless of the fact that there are a large number of plastic analogues on the market, threaded pipe tees provide a great service. The Santim company manufactures its products from high-grade brass grade CW617N and covers the parts with a nickel ball to prevent unnecessary oxidation processes. STM sanitary fittings are still of very low quality:

trace the exact geometry of the preparation;
insured for the term of service;
create airtight seals.

The tee is manufactured using the casting method, which increases the reliability of the product. The fitting gains its versatility from the combination of external and internal divisions or their combination. This tri-piece will ensure easy and quick dismantling of any main systems. Traditionally, the vibration allows you to change the main direction of the pipeline by 90°.

Threaded fittings are used to ensure a detachable connection method or change the direction of the gas main during installation and replacement of adjacent elements of the pipeline.

Types of fittings coverage:

zinc;
chrome;
nickel.

Threaded connections are most often used when working with pipes with girders up to 50 mm. For contours with a diameter of 50 mm, flange mountings are used. There is nothing behind the form and functional features, except for the parameters and type of connection are not cut, steel and high-grade chavun (ductile iron) are used for production.

Based on their intended purpose, fittings for metal pipes are classified according to their design features:

Kutniki - for directly changing pipes.
Tees – for connecting pipes of the same or different diameters.
Couplings – for bonding non-destructive structures.
Inputs - for drainage of the main line (for vertical and horizontal straight lines) under a cut of 30-180 degrees.
Plugs – for sealing highways.
Nozzles – to change the vice.
Fittings - for easier cleaning, maintenance or replacement of elements to smooth out flow.

When preparing the design, use a variety of different materials:

stainless;
brass;
midday
chavunni;
bronze

Types of threaded fasteners

The pipes are divided into metric sections. The main difference lies in its size. When connecting scorching and water mains, the inch (pipe) thread often becomes stuck. A splitter pipe can also be used to connect pipes to water heating systems, heaters, filtration systems, treatment units, and pumping units.

The pipe fittings are formed in cylindrical threaded fittings and in the connections of the internal cylindrical fittings with the outer final fittings. The thickness of the pipe walls is determined using a heavy vice.

Metric dimensions are used for pressure gauges or gearboxes. Vaughn is both internal and external. The first version is often sharpened under the name of the nut, and the other - the fitting.

Cutting parameters

Adjust everything according to its cutting diameter. An inch or mm is taken as a unit. It is important to understand that all threaded fasteners made of metal are cut in the middle.

The cross section of the pipes and the fastening made of polypropylene are flexible. So, if the cut of PP pipes is 2 cm, then this acts as an analogue of pipes with metal with a cut of 15 mm, and the situation is similar with fittings.

Straight thread threads

The corresponding parts with the right-hand grooves are screwed in or screwed behind the year arrow, left - backwards. In other words, as the threads rise towards the left in a straight line, the left is apparently split.

When installing a water supply system, be sure to check the right of distribution. The line often cracks when connecting the pipes to the batteries. On the right side of the radiators there is the right of division and storage. For the transition to the right of the split and circuit, transfer of pumps to the connection, a special set of 4 fuses (2 on the left splits, and 2 on the right), humic filters, plugs and drain valves will be required. iv.

Made from brass

Brass fittings are well suited for fixing copper pipes. Pressing the ring that is in the middle of the connection will ensure the movement of the fastening. Its location is located behind the help of a wrench. This allows you to tighten the nut to a specified level. It is important not to burn the fissures, which will cause a leak.

There is little need for regular servicing, which prevents the system from being installed below the permissible pressure.

Copper fastenings

Copper fittings are resistant to temperature changes and corrosion. Stinks can combine germs from different materials. The use of different combinations results in a reduction in operating life. It is not recommended to combine copper with galvanized unalloyed steel. This will cause corrosion processes that will lead to severe damage to the fitting and the edge of the pipeline.

Connection with Chavun

Chain fittings are connected to cylindrical threads at the ends. This material was intended to be used for valve couplings, leads, crosspieces and triplets. For a large-scale vicinity, it is necessary to place a water-resistant material. The low strength and durability of the structure is compromised by a low level of anti-corrosion resistance, which prevents manufacturers from using more resistant materials.

Steel connection

Steel structures have proven themselves to have excellent and reliable characteristics, but it is important not to forget about laying threads or strips for a smoother connection. Depending on the materials and design parameters, fittings can be subject to different parts. The main purpose of fittings is the connection of two or many contours of one and different cuts.

It is good to clean stainless steel structures that have cylindrical divisions with special reinforcements. The main advantage lies with the large-scale vikoristan. For example, if it is necessary to carry out repair work, this fastening can be disassembled and reinstalled without losing strength.

Run for pipes

The pipes are represented by pipes with pipe threads at both ends. On one side the thread is short (5-6 threads), on the other side it is long (20...30 threads). Make sure the connection of two indestructible pipes is connected. A joint is screwed into the reinforcing element or fitting, a nut and coupling are placed on the other side, a flange is wound onto the end of the pipe with a short turn of thread and covered with a reinforced coating, then it is connected to the end I'll drive you away. The coupling is screwed onto the end of the pipe and is pressed into place until it is driven out. Between the coupling and the nut there is a linen and the nut is pressed against the coupling.

Pipe outlets

The leads are adjusted to adjust the straightness of the pipeline at vertical and horizontal positions at 30°, 45°, 60°, 90° and 180°. The stench is eliminated by a smooth inner layer that overcomes the build-up on the pipes.

Based on their design features, outlets are divided into steeply curved and bent, seam and seamless. The exits from this 90° turn are especially popular.

To prepare bent leads, a pipe with a diameter is assembled, which indicates the method of preparing the structure:

cold-formed, length 15m.R;
hot-curved, with a radius of 1.5-15 m.

Serve for transporting water, gas, non-aggressive liquids at a maximum temperature of 175°C.

Steeply curved ducts are characterized by a small bend, which simplifies the layout of the highway. However, through their small parameters, the smell will not ensure compensation for the thermal expansion of pipes, for example in a scorching system. To cut out the inlets, a water-gas pipe (GOST 326275) or a seamless steel structure with a crossbar of 15 - 50 mm is used. Seamless bubbles with a large diameter are presented in the range:

When producing steeply curved pipes by stamping or hot drawing, the makers are guided by GOST 17375.2001 and operate at temperatures up to +450 C.

Threaded tees

To connect the pipes of the folding structure, there are trippers used to fix the lateral connection to the main line, which ensures a direct change at 90°.

Triplets are produced by two viconaries: the equal ones and the transitional ones. The first option is characterized by a new re-threading of all the drawers. In another case, the openings were cut in different ways.

Hardening of stamped and seamless three-pieces is allowed at temperatures of -70C...+450C, pressure up to 16 MPa.

Threaded couplings

Couplings make it possible to ensure the connection of pipes without violating the welding apparatus. During the installation process, connections to pipelines of different sizes and materials are allowed.

Couplings are classified according to the following parameters:

The connection method is a straight-through method that connects pipes with a single crossbar and a transition method for tapping pipes of different diameters.
The place of expansion is in the middle and in the middle. The first option is used to fix pipeline elements with identical rigidity. Another option is to fasten elements with varying rigidity or connect flexible elements.
Whole and rose. The remaining technology will simplify the installation due to the possibility of fixed fixation of coupling elements on pipes with further connections to the pipeline already fixed to the coupling parts.

Pipe plugs

Plugs are relevant where it is necessary to urgently and permanently block the flow of water at one or more ends of the highway. The principle of the plugs is similar to flange connections - round steel disks with openings for inserting bolts or studs for fixing. The temperature of the working core reaches +500 degrees.

The flange plugs are pressed together with the flange. Structurally, they are similar to the flange, but exclude the presence of a central opening. The prepared structure is made using the hot stamping method.

Eliptic structures are represented by a metal plate in the shape of half an ellipse. The stench reaches the pipe and serves to seal it. For production, the stamping method is also used.

The rotary plugs act as seals and seal the ends of the pipes during the grinding and turning process. The plugs will be stuck in place when the main pipelines and drainage areas are laid. The working vice varies in the range of 0.25 – 38 MPa, and the dimensions range from 23 to 1420 mm.

Threaded fittings

Nuts and fittings for pipes are used to fasten reinforcing elements. A number of devices ensure efficient operation due to sufficient tightness of the fittings. Every time it leaks, the pressure on the system decreases. To protect the reinforcing elements and achieve maximum hygiene, reinforcement elements are tightened to accommodate the heads of the nuts.

Fittings are also called pipes for releasing gas from the main line, including for tightening the vice. Below you can see the straight and end reducing fittings.

Nipeli or barila

Pipe thread adapters equipped with double-sided external connections that correspond to the dimensions of the coupling. When the pipeline lines are permanently connected, the nipple simultaneously serves for mechanical (force) fixation. For example, the radiator nipple serves to connect the battery section to each other and is selected from the left or right sections.

Types of pipes:

Barilo.
With a hexagon (between the slots there is a hexagon for manual installation).

For the convenience of buyers, below is a catalog with prices for threaded fittings. When choosing a virus to squeeze, be sure to turn over the negative side of the connector. They involve a large number of parts and spend an hour making sure the windings do not get wet. It is also necessary to ensure that the system is regularly tightened whenever the system is weakened.

Steel transition tees are used to regulate the flow of the working medium of pipelines. This type of steel transition tees is used to assemble pipes of different diameters from the main pipeline system. Steel transition tees can be used in pipeline systems, the pressure does not exceed 10 MPa and only in pipelines, and the working middle is non-aggressive. Welded transition tees are stagnant at temperatures in the range from -70 degrees Celsius to +450 degrees Celsius.

Transition tees according to GOST 17376-2001 have found their way into linear pipeline systems, as well as industrial mains, pumping stations and various compressor piping. Steel transition tees according to GOST 17376-2001 are particularly suitable for media such as gas, steam, and water.

We present to you clear transitional three-pieces of Russian production and provide a guarantee for a very low price. The price for transition tees is indicated in the catalog on our website.

Manufactured from steel, transition pipes are used in almost all production areas, from the grub industry to the oil and gas industry. The steel transition tee is also widely used in housing and communal services, in hot and cold water supply systems, and in steam heating pipelines.

The fragments of many spheres of stagnation are already consistent, the transition trie conforms to GOST 17376-2001.

Advantages of transitional triplets

The transition steel tee has a number of advantages:

Resistance to thermal infusion and temperature changes;
Tightness and reliability of the structure;
Trival term of service;
Connection of pipes of different diameters;
Possibility of dismantling.

Welded transition tee 40x25x40;
Welded transition tee 50x25x50;
Transitional tee 160x63x160.

Virology and materials

There are five ways of preparation for this. Thus, a tee that is welded from a cut pipe is called a welded transition. The transitional creatures show their greatest advantage - but this is their price. Depending on the manufacturing method, tees can be divided into welded, stamp-welded, forged, seamless and turned.

Coming from the factory, the manufacture produces various steels, chavuns, and other materials. The tee, which is used in non-aggressive environments, such as the chavunny transition, works wonders in public water supply and sewage systems. Stainless steel, such as 12x18n10t, is fused for the production of triplets for the grub industry. Triees made of cold-resistant steel (09g2s) are used in cold climate washbasins. Galvanized steel began to be vicorized if the use was extreme. The galvanized steel transition tee has 5% more weight.

Regardless of operation, the steel transition tee conforms to GOST 17376-2001.

Kriplennya
