Sandwich chimneys made of stainless steel: prices for pipes and accessories

The operation of gas heating devices largely depends on a properly selected chimney: it must be fireproof, durable and easy to use. Sandwich chimneys made of stainless steel meet these requirements: prices for products from leading manufacturers are presented in catalogs on companies' websites and in online stores. An overview of popular products and their performance characteristics will help in choosing a quality flue gas system.

Chimney sandwich pipes: price corresponds to quality

An increasing number of consumers use sandwich chimneys when operating heating equipment. The unique design of the pipe-in-pipe channel, the space between which is filled with a layer of insulation, allows the use of such systems both indoors and outdoors without deteriorating performance. They have become an alternative to brick and concrete chimney systems due to a number of advantages:

• fire resistance - the effect of high temperature is taken over by a layer of basalt insulation, protecting the outer surface of the pipe from overheating;

• resistance to corrosion - due to the use of high-quality steel for the production, pipes perfectly resist the effects of an aggressive environment;
• quick warm-up, flawlessly smooth surface - provides proper traction, excluding the formation of condensation and soot on the pipe walls;

• versatility - chimneys from a sandwich pipe are compatible with all types of heating equipment, regardless of the fuel used and can be used in rooms where the placement of chimney systems was not previously provided;
• lightness of design, simplicity and speed of installation - the chimney system does not require the creation of a base, it is quickly assembled and, thanks to the release of various components and fasteners, can have any configuration;
• elegant appearance - sandwich pipes are compact and do not take up much space.

Another indisputable advantage of insulated stainless steel chimneys is that there is no need for thermal insulation. The compressed layer of basalt wool reduces the amount of heat loss, prevents the formation of condensation and reliably protects the inner circuit of the chimney from the effects of natural factors.

Despite the fact that the prices of stainless steel chimney sandwich pipes are far from the budget, an impressive set of excellent technical characteristics makes them more and more relevant among users of heating devices. It is possible to reduce the cost of the chimney structure by using galvanized chimney pipes. Their prices are more moderate against the background of good performance indicators.

Features of the production of stainless steel chimneys

For the manufacture of chimney sandwich pipes, special alloyed and heat-resistant steel is used, the thickness of which is 0.5-0.6 mm. Due to the material's resistance to aggressive chemical attack and condensation, stainless steel pipes can be used for chimneys in combination with any type of heating equipment. The main requirement is to select the exact grade of steel for a particular device.

If the temperature of the exhaust gases does not exceed 450 degrees, chromium-nickel steel grades AISI 304, AISI 321 is used, for the exhaust, accompanied by a temperature of 800 degrees, austenitic chromium-nickel-molybdenum steel AISI 316 is suitable. The standards and requirements for the materials of chimneys are developed by the American Institute of Steel and Alloys (AISI). They are also used in domestic production of pipes for chimney systems.

Considering that many make products in a handicraft way, you can buy low quality stainless steel chimney pipes. Therefore, it is very important to focus on the availability of certificates that meet the requirements of European standards. Manufacturers of such products are implementing modern technologies of world leaders in this field and adopting their experience. They sell products not only of typical diameter, but also to order parts of non-standard dimensions.

In addition to sandwich structures made of stainless steel, galvanized pipes for chimneys are produced. The price for such products is much lower, and the service life, if used correctly, can reach 12-15 years. For this, steel is used, the thickness of which is at least 1 mm, since chimneys with thin walls quickly burn out.

You can buy galvanized pipes for a sandwich type chimney in two versions. In one of them, both pipes (external and internal) are made of galvanized steel, but it should be noted that such a structure can deform at temperatures above 450-500 ° C. Another option is when the inner contour of the structure is made of stainless steel, and the outer one is galvanized. In this case, the outer pipe is 1 mm thick, for the inner one, 0.5 mm is sufficient.

Rational use of galvanized steel chimneys. Pipe prices

The use of galvanized steel for chimneys is a matter of controversy. This material is cheaper than the price of a stainless steel chimney pipe, the cost of a meter sandwich pipe in a galvanized casing will be about 900 rubles. However, there is a danger of the harmful effects of galvanizing on the health of people in the house. Before buying a galvanized steel chimney, you must consider the existing risks and operating features.

The fact is that when using such chimneys, negative effects described in the guides of galvanized metal characteristics can occur:

• pure zinc itself does not pose a health hazard and is contained in some human organs;
• galvanized steel, when heated above 420 ° C, forms toxic fumes that can cause poisoning;
• during the production of technical zinc, harmful impurities are added to its composition: arsenic, lead and others, thereby giving it the necessary performance properties. It is these additives that are harmful to humans.

For these reasons, it is safer to use chimneys made in the form of a sandwich construction, where the inner pipe, exposed to high temperatures, is made of stainless steel. Also, a galvanized chimney can be used for chimney systems with low exhaust temperatures.

Helpful advice! If in heating equipment the heating temperature of the sandwich pipes for the chimney does not exceed 350 ° C, it is possible to use products made of galvanized steel without harm to health.

Manufacturers produce galvanized single-circuit and sandwich pipes, in which the inner pipe is made of stainless steel. The former can be used as temporary chimneys for non-residential premises: change houses, warehouses, garages. For apartments and cottages, it is better to buy insulated sandwich-type chimney pipes.

As for the price of galvanized chimneys, it is 2-3 times less than the cost of similar stainless steel pipes. However, the latter are distinguished by their reliability, long service life and can last up to 25 years. And given the possible negative impact of zinc on human health, stainless steel products still have a clear advantage.

Chimney pipe diameter

In the technical documentation, manufacturers indicate two values ​​for the diameter of a sandwich pipe for a chimney. The first is the section of the inner pipe, the second is the diameter of the outer one. The dimensions of the sandwich pipes for the chimney are selected depending on the combination with which equipment they will be used. The less powerful the heater, the smaller the cross-section is required for the flue duct.

The internal section of the chimney must correspond to the diameter of the outlet pipe of the heating device. It is the inner tube that experiences the main effect of the temperature of the discharged combustion products. Therefore, its section should not be less than the diameter of the outlet. The power and dimensions of the heating equipment used are regulated by the requirements of SNiP.

You can buy sandwich chimney pipes produced by leading manufacturers with the following dimensions:

• inner section diameter - 110, 115, 120, 150, 200 and up to 300 (mm);
• outer section diameter - from 200 to 430 (mm);
• steel thickness of the inner pipe - 0.5 and 1.0 (mm);
• the length of a separate pipe segment is half a meter and 1 m;
• thermal insulation layer thickness - from 40 to 60 (mm);
• shaped parts - swivel bend at 45 and 90 degrees, tee at 45, 90 and 135 degrees.

In addition to the main components of the sandwich chimney, you can buy additional elements for the complete assembly of the structure. Manufacturers offer for sale:

• revision tee for removing dirt on loungers (horizontal sections);
• compensator - regulates the change in the linear dimensions of the sandwich structure when the temperature changes;
• nodes of the passage of the roof and floors, decorative overlays of the nodes of the passage;
• roof seal for the roof outlet;
• plugs, weather vane, tops;
• protective aprons, support platforms;
• brackets, stretching clamps.

Thanks to the factory production of a large assortment of fittings and fittings, it is possible to significantly reduce the cost of installing chimneys from sandwich pipes (prices for products do not include installation costs). Simple installation allows you to assemble the chimney structure yourself.

Stainless steel chimney size

One of the main factors for the efficient operation of heating equipment is the height of the chimney. The chimney size of the stainless steel sandwich determines the draft formed in it. And if its strength does not correspond to the norm, there is a threat of carbon monoxide entering the room and stopping the operation of the device. In order to ensure normal draft force, the chimney length must be at least 5 m.

How high should the chimney pipe be? There are norms for the height of chimneys relative to the roof, adjacent buildings, windows, doors, ventilation ducts. The main ones are applied to chimneys, regardless of their design and the heating equipment used.

If a ventilation duct is located in the immediate vicinity of the chimney, then the chimney pipe should rise 0.2 m above it, since otherwise carbon monoxide can enter the room.

Chimney height relative to the roof of the house:

Distance from chimney to roof ridge, m	Chimney head length, m
≤ 1,5	≥ 0,5
from 1.5 to 3	Skate level
≥ 4,5	Below the ridge, so that the angle between the level of the ridge and the edge of the chimney is 10 degrees
In the case when the building has a flat roof	≥ 2

 

A pipe that rises above the roof by more than 1.2 m must be fixed with guy wires.
If a residential building is located next to the boiler room, the chimney pipe should rise 1.5 m above its roof.

Correctly sized chimney sandwich pipes play a key role in the formation of draft. If the chimney is narrow and excessively high, an increase in aerodynamic resistance and, as a result, a deterioration in draft can be observed. If the pipe is wide and low in height, the smoke will cool off quickly, which will lead to condensation on the walls, the formation of soot and also reduce draft.

Helpful advice! The height of the chimney must comply with fire safety standards. Do not locate the boiler room chimney close to windows, doors and roofing, as the sparks generated can become a source of fire.

Recommendations for choosing a stainless steel sandwich chimney: consumer reviews

Before you buy a stainless steel sandwich chimney, you should familiarize yourself with the main selection criteria, as well as user reviews about a particular manufacturer. First of all, the material is selected from which the inner contour of the sandwich structure is made. Professionals recommend that the inner tube is made of stainless steel. The outer contour can be made in several versions: here the choice is influenced by the price of the chimney pipe.

If we talk about economic benefits, then you can buy a stainless steel chimney along the inner contour and galvanized on the outside. Thus, the cost of the sandwich construction will be much lower, and the technical parameters will not change. It is necessary to pay attention to the thermal insulation layer: it can be of different thickness, which also affects the cost of the structure.

Helpful advice! For the sake of economy, it is impossible to use simultaneously single-wall and sandwich pipes in one chimney. This will lead to a deterioration in the thrust and deformation of the single-circuit sections of the channel.

It is possible to purchase pipes and accessories separately or as a ready-made kit. In order for the composition of the kit to be fully matched, it is necessary to first prepare the chimney diagram. The scheme takes into account all the available sections of the passage of pipes through the roof or wall, as well as the accessories necessary for assembling such a configuration. It is important here that all elements are kept in the same diameter.

It is also worth focusing on the total length of the chimney. It must be calculated in advance so that the number of pipe sections required for installation can be determined.Considering that manufacturers produce pipe segments of various lengths (0.5 and 1 m), this will help avoid buying unnecessary elements.

As for the service life, quality and price of stainless steel chimney pipes from different manufacturers, here you may need feedback from buyers who have been using this product for a while. On any of the company's websites there is a section with consumer reviews, where you can get acquainted not only with the cost and quality of the purchased products, but also with the level of customer service.

Tips for self-installation of chimneys. Professional installation prices

The modularity of the design and the ability not only to buy stainless steel chimney sandwich pipes, but also all the accessories for them, makes it easy to carry out self-assembly. But it's still worth familiarizing yourself with some installation guidelines:

• installation begins with a horizontal section from the outlet of the equipment;
• observe the slope of the horizontal pipe section for condensate drainage;
• the connection of the inner pipes to each other is carried out by putting the next pipe on the previous one in order to avoid the penetration of carbon monoxide into the room. Outer pipes are assembled on the contrary, by installing the next one in the previous one, thus providing protection from moisture;
• docking places are treated with heat-resistant sealant;
• sections of pipe passages through the ceiling or wall are insulated with non-combustible materials;
• in places where the chimney passes through a wall or ceiling, only solid pipes are used: in these places, pipe sections cannot be joined;
• when the chimney passes through the roof, a special pass-through unit is used;
• immediately after the pipe is brought to the street, a tee is installed for the subsequent collection of condensate;
• external fastening of the sandwich pipe to the wall is performed at least once for every 1.5-2 m;
• chimney installation work always ends by checking the draft in the system;

Helpful advice! Fire safety design of sandwich chimneys allows them to be installed for heating equipment in houses built from almost any material.

To be sure that the design meets all the established requirements of SNiP, it is better to invite specialists to assemble and install the chimney. The cost of work is determined in different ways. Some companies tie the cost to the installation price of one section, which can vary from 1600 to 2100 rubles. The price of installing a sandwich chimney in a standard set, excluding materials, ranges from 20,500 to 35,500 rubles.

Such a range of installation costs is determined by many factors: the number of passes through the floor, wall, roof, the total length and configuration of the route, the possible manufacture of a box and many other circumstances. It is possible to pre-navigate the installation price by inviting a specialist to measure and estimate the services.
