Advantages of metal chimneys
Compact chimneys made of stainless steel have successfully pushed brick structures and ceramic pipes in the market for this specific equipment. Historically, the field of application of metal pipelines for gas and smoke removal was in the field of industrial construction, but a number of successful engineering developments contributed to the introduction of steel tap systems into low-rise residential projects.
- Specific weight of material .Comparatively low index compared with brickwork or ceramics. In simple heating projects with a single heat source( furnace, boiler, water heater, etc.), even with internal wiring, a separate foundation for the pipe system is rarely required.
- Corrosion resistance .Alloyed steel is inert to most aggressive chemical compounds, so such metal chimney pipes have an almost unlimited lifespan.
- Aerodynamic properties of .The polished internal surface of the chimney does not prevent the free movement of volatile combustion products( if there are no stagnant zones, and all structural elements are calculated and assembled correctly).
- Easy installation of the chimney .Installation of a metal chimney can be done even with their own hands, though only after a careful reading of the manufacturer's instructions.
- Relatively low price .Let's compare three typical versions of steel pipes for a chimney( the diameter is indicated externally):
| Type of pipe | Diameter, mm | Thickness, mm | Price per meter |
| Stainless without insulation | 100 | 0,5 | 500 |
| In galvanized casing | 200 | 0,5 | 1080 |
| Stainless steel housing | 200 | 0,5 | 1600 |
Metal chimney:
equipment As a rule, every self-respecting manufacturer of thermal equipment not only indicates the installation characteristics of the smoke exhaust structures in the passport, but also supplies a set of necessary for the monstersmetal parts of chimneys of connecting elements. This list can include:
- bends at 45 and 90 degrees, allowing rationally to build pipelines inside the premises;
- tees on 45 and 90 under the outputs of several instruments or for dead-end devices: the end plug, sump or inspection hatch in many cases is a mandatory structural element;
- condensate collectors, silencers are mounted at the beginning of the circuit;
- umbrella outlet nozzle, deflector( pressure equalizer), roof penetration units - these are the final devices for the installation of chimneys made of stainless steel;
As you can see, the developers have provided all the details of your future chimney, it remains only to thoroughly approach his project, calculate the scheme and make the right choice of fittings.
Installation of metal chimneys
Stepwise installation of a chimney from metal pipes can be traced through video instructions, but even without it, a person with his head and hands can properly assemble this structure without violating the integrity of the ceilings and roofing.
Here are some simple recommendations for assembling smoke ducts in an apartment building.
- It is necessary to dance from the "stove", i.e.begin the assembly of the entire circuit from the heat unit, which the smoke generates, and finish with the installation of a chimney on the roof.
- Docking units of metal sections of the chimneys before planting are best treated with a special heat-resistant sealant.
- Piping in the house is rationally carried out on the surface of the supporting structures( on special brackets with a step of not more than 1.5 m with mandatory heat insulation of the walls).The qualitative fastening of the chimneys ensures not only the durability of the heating system, but also your personal safety.
- Overlapping passages are equipped with special inserts, exit to the roof - a unit of waterproofing and thermal protection.
- Fixation of chimney pieces should only be carried out using standard clamps, usually supplied in the product package( less often - by the manufacturer separately).
If you do not dare to install a metal chimney yourself in your country house, now, at least, you can control the work of professionals.
