Chimney made of steel pipe by hand. Installation and construction

If you decide to make a chimney from a steel pipe yourself, it is important to get acquainted with the technology of the work, as well as to ask what parameters should be used to select the product.

Fire safety

It should be noted that as a cause of fires in private homes, in most cases an improperly arranged chimney appears. If you decide to install a furnace, chimneys for such equipment must be equipped with a certain technology. If we ignore the rules, the removal of exhaust gases from the living quarters will be bad. If the installation of a steel pipe or its intermediate elements has been carried out without observing the technology, smoke can occur in the room, and carbon monoxide can begin to flow into the living space. Most often under these conditions, reverse thrust is observed.

In order to avoid such problems, it is necessary to choose the correct diameter of the chimney, and also to make the installation according to all the rules. Thus, do not use pipes with one wall, if you plan to use them in the process of continuous use of the stove or fireplace. Such elements are applicable for connection or repair of a certain part of the chimney. The use of single-walled pipes is still sometimes used for a brick chimney.

Advice of a professional

If you decide to install a chimney from a steel pipe yourself, then it is recommended to use double-walled products made of stainless steel. Between the pipes a heater is used, the thickness of which is calculated in such a way as to prevent the formation of condensate.

Why use a steel chimney

Ceramic and brick chimneys are most often replaced by steel. This is due to the fact that such pipes can be installed at any time of the year, among other things, their weight is negligible, which eliminates the need to equip the foundation. Consumers note that steel pipes with the addition of titanium have high strength. During operation, they are not deformed and are able to undergo a temperature of up to 600 degrees. If there is a need to use products of higher strength, then one should prefer those whose walls have a thickness of 1 millimeter.

The chimney made of steel pipe is very simple to install, these products do not deform from mechanical impact. The surface of the metal after heating the furnace quickly heats up and begins to transfer heat to the room. However, it is necessary to be prepared for the fact that the base of the steel pipe cools quickly enough.

Pipe Selection Features

Before you start the work, you have to pick up a chimney. It is important to take into account several important points. Among them, we can distinguish the dimensions of the output of the boiler. The dimensions of the pipe should not be less than the corresponding diameter, which is characteristic of the branch pipe of the heating equipment. The chimney pipe should be worn by the master at the exit, and not vice versa. On sale it will be possible to find pipes whose diameters range from 115 to 200 millimeters or more.

Mounting recommendations

To carry out the work you will have to purchase pipes, the length of which is equal to 1 meter. The chimney in the house is made up of the main parts. It will take a workpiece and a tee, designed to inspect the pipes. It is important to buy a tee to collect condensate, which is used to clean the joints. If the pipe will have rotations equal to 45 degrees, then you need corners that are made of the same material. Take care of the presence of a compensator, it takes the burden of expanding the elements of the chimney when cooling and heating. The system should be put on the roof, for this purpose the adjacency node is useful. In order to prevent rain, leaves, snow and dust from entering the system, it is necessary to equip the system with a headpiece.

Technology of work

If you will install a chimney from a steel pipe yourself, then initially you need to perform a horizontal part of the system. In the place where the pipe will be connected to the heating equipment, it is necessary to make the connection, using the typical transition elements for this. The connection should be made with the help of crimping clamps. In the central part of the pipe, you should mount the tee for revision using the clamps. Chimney in a private house is arranged according to a method that involves putting each subsequent segment on the previous one. Do not violate this rule, while the smoke will pass through the room without leaving the outside.

As for the chimney deflection in the horizontal section, it should be directed from the heating equipment downwards. This is necessary for condensate to flow in the direction that leads away from the boiler. The two ends of the horizontal section should be placed at a height of 7 millimeters from each other.

Recommendations of the masters

If you decide to build a chimney in a private house, then it is not necessary to match the output of the heating equipment with the through pipe by the method of horizontal connection. This can cause a reduction in thrust. In the place where the pipe will go out through the wall, it is necessary to equip the insulation layer, which will consist of non-combustible materials. If you have to work with wooden walls, then it is important to wrap the pipe with asbestos, and afterwards to consolidate non-combustible materials. In the presence of clay, concrete or brick walls, the hole should be sealed with a construction foam designed for outdoor work. In those areas, which the pipe will pass through the wall, it is forbidden to connect. If such a situation is unavoidable, then the pipe must be cut and mated prior to crossing with the wall.

When installing steel chimneys, it is important to carry out the work correctly at the stage of the elements leaving the street. In the place where you are supposed to turn up, you should mount a T-capacitor. To connect this element to the outlet of the pipe, a crimp clamp should be used. Specialists recommend to use a special bracket. It is important to make the tee heat insulation, which is true if it is located quite low and serves as a place where you can get injuries from burns.

What is important to know the master

Steel chimneys require compliance with fire safety. It is possible to provide cleaning holes, for this it is permissible to use a removable glass or a door. The audit should be at the base, in the immediate vicinity of the heating equipment. Taps and joints, as well as other elements must be connected with clamps, which are treated with a sealant, the operating temperature of the latter should be equal to 1,000 degrees and more. When mounting vertical sections, it is necessary to mount in steps of 2 meters.

As for the horizontal sections, their length should not be more than one meter. In those places where the chimney will pass through the roof or walls, as well as the ceiling, it is necessary to make holes, they must have a more impressive size than the pipe itself. Thus, you must exclude the possibility of contact of materials with the roof or floors. To close the gap, use square steel plates. Among other things, in the course of these works, a through-hole should be used, which is made of stainless steel and a heater. When chimneys are made of stainless steel, the final stage is the installation of a head that acts as an umbrella against rain.

Conclusion

If you decide to make chimneys yourself from stainless steel, then you can cut out the blanks for the chimney. Using a straight pipe, you need to cut at an angle of 75 degrees, this will form a connection angle, which is 150 degrees. To do this, the previously cut pieces must be reversed and reconnected diagonally. When installing the furnace chimneys are absolutely necessary. If you cut the pipe at an angle of 60 degrees, you will be able to form a rotation equivalent to 120 degrees. Knowing these rules and nuances, you will be able to avoid spending on acquiring new elements that would constitute a complete smoke extraction system.
