Sandwich pipe chimney: How to properly mount

Sandwich pipes for chimneys are ready constructive solution, suitable for use inside buildings, and for outdoor use. Such constructions assembled from ready-made fittings, regardless of the stage of building a house. They are light, have a smooth inner surface and do not require thermal insulation, as are fire resistant thermal insulation layer. Installation must meet all of the requirements for chimneys.

Tubes of stainless steel for chimney

Stainless steel - the actual material has found application in a variety of designs, including the production of smoke escape channels. Using a stainless steel tube for chimneys in virtually all types of heating equipment due to resistance material to corrosion and hostile environment generated as a result of condensation of water vapor allocated products.

However, not all types of steel can be used for chimney construction. Selection of a steel grade suitable for flues depends on product outlet temperature: 400 ° C using chromium-nickel steel AISI 304, 321, and 800 ° C - heat resistant steel of hromonikelmolibdenovaya AISI 316. As for galvanized or black steel, they do not have corrosion protection and as a chimney quickly burn out.

The indisputable advantage of stainless steel for chimney pipes are:

• light weight - contributes to ease of assembly and does not require the construction of the foundation;
• modular system - a huge number of pipes and fittings of different diameters allows you to build not only the construction of the house of new construction, but also in the lived-in room;
• easy installation - quality fasteners ensures gas-tight assembly error-free design. Furthermore, such chimneys can be deflected from the vertical state to bypass all sorts of obstacles;
• smooth inner surface;
• resistance to burn-- contributes to long-term operation of the chimney;
• thin-walled tubes - allowing the system to quickly be heated at startup, reducing the formation of condensate and providing good traction.

Steel chimneys are produced in two versions:

• single wall (single-layer, single-circuit) - these flue systems are designed for use in heated buildings, connection of the boiler to an existing flue system or for repair and restoration by the old chimney readjustment;
• double-walled (three-layer, double-sandwich pipes) - in sandwich construction of pipes for the flue has heat insulation layer disposed between the two pipes of different cross sections. Such a pipe arrangement makes it possible to mount them on the inside and outside of the building without a warming device. Isolation produce only places the chimney passes through the ceiling, wall or ceiling.

Chimney unit from steel pipe with your hands: the basic rules

Modular construction and a wide range of all component parts makes the independent performance of the chimney installation of stainless steel as simple as possible. But despite the ease of installation, these chimneys are part of the overall functioning of the cycle gas equipment and must meet the requirements regulated SNIP and gas safety regulations economy.

How to install a chimney? It is worth to get acquainted with the thematic video instructions before you assemble the chimney made of stainless steel. On the internet you can easily find a series of video installations chimney stainless steel with their hands. Rollers contain a lot of useful information about the nuances of the installation and the most frequent mistakes when installing the chimney with his hands.

Despite the simplicity of assembly, flue gas discharge device is better left to professionals than to carry out the installation of their own hands. stainless steel flue must meet the following requirements:

• if the exhaust single-loop applied steel pipes, will be most acceptable use the internal circuit of the chimney, in which case the mounting system positioned along capital internal walls;
• pipe diameter should be suitable in size to the lead pipe fume collection gas boiler that will provide reliable sealing structure;
• Chimney pipe arrangement at the connection to the boiler must be vertical and have a length of 50 cm or more;

• if finishing wall, close to where the steel chimney mounted, is made of combustible material, the distance from the tube to the wall should not be less than 25 cm, if installation requires a closer location, you need to upholster wall shields so that the interior of the wall stood for pipe dimensions of 15 cm on each side;
• It is forbidden to use in construction of more than three rotary knee;
• chimney length should be not less than 5 m;
• the height above the roof chimney pipe should exceed 0.5 m;
• availability of design revisions, tees, and the condensate is necessary.

Useful advice!During installation chimney system yourself, remember that the wrong set design could cause a gas explosion, fire and carbon monoxide poisoning.

Use of a sealant for stainless steel chimney

Answering the question of how to make the chimney safe to say that in order to secure its operation, the design must be completely sealed. Achieve complete tightness and moisture protection structure can be processed low places system elements for special sealant stainless steel chimney.

It is worth noting that the special silicate heat-resistant sealants are used for chimneys. Before installing the flue pipe on the previous link, their joints are treated in the composition. sealants well connected with the majority of materials: stone, metal, concrete, ceramics. Considering that the surface of a stainless steel flue elements is smooth, it is recommended to apply the abrasive treatment before use sealant.

Job processing sealant held at a positive temperature of from 20 to 40 ° C: it will provide a quick drying composition. If you miss the mark sealant all adjoining surface, you get a monolithic structure, which will be difficult to disassemble without damage. This is worth considering if in the future will need to disassemble some parts of the chimney for the service.

processing sealant produced using the gun, causing paste layer thickness of not more than 1 cm. It is not necessary to apply a layer of the composition of a large: they can not sufficiently dry, and if they dry out, it will continue to crack. Some sealants chimney dried for several hours at different temperatures, as will be indicated on the package. Sealants are available for chimneys only gray and black.

Useful advice!Work the sealant is necessary to wear protective gloves, as in contact with the skin, they can cause chemical burns.

How to insulate the pipe of the chimney with his own hands

Insulation tubes chimney solves several problems, the main of which - preventing destruction the design of the roof adjacent to the channel, and the protection of the chimney from the effects of adverse natural factors. In addition, when the thermal insulation significantly reduces heat loss, which also has a positive effect on the processes occurring within the system.

Insulate the pipe, can significantly extend the service life of the chimney due to the following factors:

• minimizing the ingress of reactive condensation on the inner surface of the pipe;
• action decreases the temperature differences between the outgoing hot fluids, cold and atmospheric air;
• heat losses contribute to energy saving, which generally allows economically consume fuel;
• increases the mechanical strength of the whole structure, as the Insulating housing serves as a framework,

The warm metal pipe chimney? Basic requirements for the insulation material - it is non-combustible, and should be commensurate with the weight of the insulation material of the roof of its ability to survive, otherwise it just selling it. Particularly suitable for the chimney insulators are glass wool or mineral wool. It can be purchased ready-made cylindrical structure with a protective layer of foil. They come in different diameters, so you can choose the right option under construction.

Before Doing the work yourself, you can familiarize yourself with the video as warm chimney with his hands. A clear description of the installation will help to perform fixation of insulation joints, using the most suitable materials.

Useful advice!It is desirable to provide insulated chimney at the design stage of construction.

Recommended Installation of sandwich pipes for flues

Performing assembling a sandwich of stainless steel chimneys, should adhere to the following guidelines:

• when installing sandwich chimney must be remembered that the structure should not have horizontal sections of pipe length from 1 m;
• It is necessary to eliminate contact fumes pipe with electrical wiring, piping, gas appliances;
• execution chimney through the wall mounting device is accompanied by isolated pipes in these areas;
• when assembling the sandwich pipe to the chimney with his hands, should be provided Audit window for maintenance and cleaning of soot.

How to install a chimney pipe of a sandwich? Before installing the structure, it is necessary to know how to calculate the diameter of the chimney and its total length. section of the pipe is chosen depending on with which gas equipment it will be applied: the more powerful device, the larger diameter should be chosen. The value of the diameter is specified in the technical specifications for the device.

Another important dimension of the pipe for the chimney sandwich - its total length. design length should not be less than 5 m. If the flue assumes bias for his knee devices use from 20 to 90 degrees. the outer part of the tube length should be such that it exceeds the level of the ridge of the roof to not less than 0.5 m, if it from the ridge to 1.5 m. In the case where the chimney is removed from the skate to 3 m, the length of the tube may be flush with them.

Before you assemble the chimney of sandwich pipes, should be familiar with key stages of assembly. Get a clear idea of ​​the installation by viewing the online video assembling sandwich chimneys. Basic installation rules:

• inner pipes sandwich structures are joined to the upper contour of the lower pipe and the outer vice versa. On the one hand, this provides an unobstructed removal of smoke from the other - protects against moisture;

• docking space portions where the tube is joined with the equipment, and also places the chimney passing through the fixed roof with clamps;
• to improve the bond strength low heat resistant processed hermetic seams;
• a flue for serving integrated structure tee audit for removing moisture - kondesatosbornik;
• an outer pipe section is provided with a head part to prevent foreign objects in the channel.

Features chimney installation of sandwich pipes through the wall

When installing the flue through the wall is necessary to observe the basic rules and requirements for the installation of chimney channels. However, there are some nuances that need to be taken into account in deriving the chimney through the wall. If the first unit is planned to withdraw the chimney into the wall horizontally, you need to make a small deviation from the device. This will prevent the ingress of condensation inside the boiler.

How to install a chimney through the wall? There are two ways: it is possible to raise the channel-to-ceiling and this level output or exit chimney make space through the wall at inlet of the gas appliance. From the standpoint of ease of installation and use of shaped parts, the second method is more preferable since it has a single pivoting knee.

The order of execution of works on the device through the wall of the chimney:

• punches a hole in the wall, which will host pipe. Its dimensions must be such as to conform requirement SNP: distance from the outer surface of the tube to the wall 0.5 m. In order to shorten the distance to 0.38 m, the hole or cased sheet metal is inserted into it metalwork box;
• inserted into the prepared hole of sandwich pipe for chimney stainless steel so that the joints do not fall into a passing knot. The tube is fixed, and the space between the casing and the channel is filled with temperature insulation;
• horizontal section length should not exceed 1 m;
• hole in the wall close decorative overlays are realized, complete with trumpets;
• the outer side wall fix the retaining bracket and swivel under the channel outputted;
• a vertical pipe portion fastened to a wall so that the spacing between fasteners was not less than 2 m.

Useful advice!It is strictly forbidden to insert between the sandwich pipes are generally single-loop pipe. The whole system should consist of identical tubes.

Mounting of sandwich chimney pipe through a roof

Before the device chimney sandwich pipe through the roof, you need to plan the withdrawal right place. The fact is that, given the configuration of the roof structure, not in all the places you can infer the chimney through the roof. These include:

1. Valley, where accumulates a lot of rain and it is difficult to provide waterproofing.
2. In close proximity of roof windows.
3. Opposite the windows of adjacent housing.

Before you install the chimney through the roof, it should also take into account the location of the overlapping beams and rafters. The channel must be arranged between these elements. To offset the chimney line can be used using two rotary knee at 45 degrees. The sequence of work for the implementation of the passage through the roof of the chimney sandwich:

• an opening in the ceiling is done according to current standards;
• holes protect the ends of the material is not susceptible to combustion;

• formed vertically in the box is put a pipe. It should be noted that the chimney can not be rigidly secured, it must be free to move up and down, as by heating will change its length;
• the space between the pipe and the casing is filled with basalt wool on the basis of previously input location sewing up the metal sheet. In the space between the screen and the ceiling lay the cardboard of the mineral wool. It is possible to simplify the organization of the passage of smoke through the roof and ceiling, if you buy ready-made ceiling passing an assembly of prefabricated boxes and decorative screen of stainless steel;
• for the passage of the chimney through the ceiling, arrange a hole in the roofing cake. Layers of cake incised crosswise, so that they may be under and secure the bracket. The hole in the lath makes that the distance from the edge of the passage to the pipe surface from all directions was at least 13 cm;
• all received the ends of the holes close fiber-cement plates - mineritom.

When the device passes through the chimney from the roof or other metal roofing, use special universal master seal flush. His mission - quality sealing area when passing a chimney through the metal roofing. Roofing skirt seal is shaped roofing material, whereupon it is fixed to the surface. Connecting line seal with the pipe and the roof surface treated heat resistant sealant.

Embodiments of heat exchangers in the flue pipe

To use the heat produced by removing the combustion products, a special device is used - the heat exchanger to a chimney pipe. There are various options for these devices, among which are the most relevant:

1. Air heat exchanger - principle of operation of this device is identical to the operation of the convector. Cold air enters through the inlet into the heat exchanger, after which the heated stream exits through openings at the top of the device. As a result, additional heating of the room. Having a defined set of tools and skills to air heat exchanger can be done independently.
2. Structure of coil type - for such devices use flexible, corrosion resistant copper or aluminum tube. They are bent to produce the desired shape, in the final sections of the pipe make a thread for connection to the expansion tank. it is recommended to protect pipes special casing for security and improve heat transfer. The principle of operation of such a heat exchanger - natural circulation of water. Its easy to install on their own, however, it is necessary to settle the weight, taking into account the properties of the liquid to expand when heated. The disadvantages of such a system include the reduction in carbon monoxide output temperature that could adversely affect the thrust and fuel combustion.
3. Water tank - for the device of such a device will need a copper tube and the metal tank capacity of about 20 liters. Capacity can be made independently of the steel sheet. The bottom and top outlets of the tank bore holes. The bottom discharge tank crashed draining tap water.
4. The apparatus of corrugations - for the manufacture of such a heat exchanger is used of three corrugated tubes which are wrapped fumes pipe at the point of passing through an attic floor. Surface corrugation chimney gives off heat, and the heated stream of it is directed into the room, which is necessary to heat. The operation of this heat exchanger reduces the temperature of the chimney, thereby providing fire protection.

Where can I buy a sandwich pipe for the chimney

Because the functioning of the system depends flue gas boiler work for assembling the sandwich chimney must acquire quality and proven tube. Only such products can guarantee a safe and efficient removal of the exhaust gases, which excludes ingress of smoke into the room and the emergence of reverse thrust.

It is very profitable to buy the necessary goods through the Internet sites of the producers: you can in a relaxed atmosphere to explore the range, do comparative analysis of the prices of different manufacturers, and most importantly, get expert advice about choosing a model suitable for the particular equipment. Many online stores include in their services and delivery of goods.

As a rule, many companies involved in the implementation of pipes for chimneys, offers professional installation of the chimney. Price per operation depends on the wall thickness, the material from which the pipe, the presence of the passage through the wall to the flue, the configuration and the roof covering. Approximate price of the installation of the chimney sandwich pipes is 1900 rubles. 1 PM Departure gager, connection equipment, fire-retardant work in fees for the installation of chimneys of sandwich pipes are not included.

Some online stores engaged in the sale of galvanized pipe for the chimney in the sandwich design. This material is cheaper, but it has a good technical performance. Chimneys galvanized steel may be used for removing the low smoke point. If the device chimneys of sandwich pipes involves only the outer contour of galvanizing, such a construction can be operated without any harm to the health. How profitable is the acquisition of a chimney of a material can be found by analyzing the level of prices.
