If you decide to make a chimney from a steel pipe yourself, it is important to familiarize yourself with the technology of the work, as well as ask what parameters should be used to select a product.
Fire safety
It is worth considering that the overwhelming majority of cases are caused by improperly equipped chimney as the cause of fires in private houses. If you decide to install the furnace, chimneys for such equipment should be equipped with a certain technology. If you neglect the rules, then the removal of exhaust gases from the living room will be bad. If the installation of the steel pipe or its intermediate elements was carried out without observing the technology, smoke may occur in the room, and carbon monoxide may begin to flow into the living space. Most often, under such conditions, reverse thrust is observed.
In order to eliminate such problems, it is necessary to choose the correct diameter of the chimney, as well as install in accordance with all the rules. Thus, you should not use pipes with one wall, if you plan to operate them in the process of constant use of the stove or fireplace. Such elements are applicable for connecting or repairing a specific part of the chimney. The use of single-wall pipes is still sometimes used for a brick chimney.
Professional advice
If you decide to make a chimney from a steel pipe with your own hands, it is recommended to use double-walled products made of stainless steel. An insulation is used between the pipes, the thickness of which is calculated in such a way as to prevent the formation of condensate.
Why is it worth using 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 insignificant, 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 endure temperatures up to 600 degrees. If there is a need to use products of higher strength, then those whose walls have a thickness of 1 millimeter should be preferred.
It is very simple to install a chimney from a steel pipe with your own hands, such products do not deform from mechanical stress. After flooding the furnace, the metal surface heats up quite quickly and begins to transfer heat to the room. However, you must be prepared for the fact that the base of the steel pipe cools quickly enough.
Pipe Selection Features
Before you start work, you have to pick up a chimney. It is important to consider several important points. Among them, the sizes of the boiler output can be distinguished. The dimensions of the pipe should not be smaller than the corresponding diameter, which is characteristic of the pipe of the heating equipment. The master will have to put the chimney pipe on 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.
Installation Recommendations
To carry out the work you have to purchase pipes whose length is 1 meter. The chimney in the house is made up of main parts. It will also be necessary for work and a tee designed for pipe inspection. It is important to buy a condensation tee, which is used to clean joints. If the pipe will have turns equal to 45 degrees, then you will 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 upon cooling and heating. The system must be displayed on the roof, for this, a junction node is useful. In order to prevent the ingress of rain, leaves, snow and dust, a system should be provided with a cap.
Technology of work
If you will equip a chimney from a steel pipe with your own hands, then initially you need to perform the horizontal part of the system. In the place where the pipe will be connected to the heating equipment, you should connect using standard transition elements for this. The connection should be carried out using crimp clamps. In the central part of the pipe, a tee for revision should be mounted using connecting clamps. The chimney in a private house is equipped according to the method, which involves putting on each subsequent section to the previous one. This rule should not be violated, while the smoke will pass in the room without moving out.
As for the slope of the chimney in a horizontal section, it should be directed down from the heating equipment. 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 located at a height of 7 millimeters from each other.
Masters Recommendations
If you decide to arrange a chimney in a private house, then you should not pair the output of the heating equipment with the pipe inlet using the horizontal connection method. This may cause a decrease in traction. In the place where the pipe will go out through the wall, it is necessary to equip the insulating 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 then strengthen non-combustible materials. In the presence of clay, concrete or brick walls, the hole should be sealed with construction foam designed for outdoor use. In those areas where the pipe will pass through the wall, it is forbidden to make a connection. If this situation is unavoidable, then the pipe must be cut off and mated before crossing the wall.
When steel chimneys are installed, it is important to carry out the work correctly at the stage when the elements exit onto the street. In the place where you plan to turn up, you should mount a tee-capacitor. To pair this element with the outlet of the pipe, a crimp clamp should be used. Specialists recommend using a special bracket for provision. It is important to insulate the tee, which is true if it is located quite low and serves as a place where injuries from burns can occur.
What is important for the master to know
Steel chimneys require fire safety. Openings for cleaning can be provided, for this it is permissible to use a removable glass or door. The audit should be in the base, in the immediate vicinity of the heating equipment. Bends and joints, as well as other elements must be connected with clamps that are treated with sealant, the working temperature of the latter should be equal to 1,000 degrees or more. When installing vertical sections, fastening should be carried out in increments 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 should have a more impressive size than the pipe itself. Thus, you should exclude the possibility of contact of materials with the roof or floors. To close the gaps formed, square steel plates should be used. Among other things, in the course of these works, a passage glass should be used, which is made of stainless steel and insulation. When stainless steel chimneys are equipped, the final stage is the installation of the head, which acts as an umbrella from the rain.
Conclusion
If you decide to independently make chimneys from stainless steel, then you can cut blanks for chimney flue. Using a straight pipe, you need to make an incision at an angle of 75 degrees, this will allow you to form a joint angle, which is equal to 150 degrees. To do this, previously cut parts must be turned over and re-connected diagonally. When installing the stove, 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 the acquisition of new elements that would constitute a complete flue system.
