Asbestos pipes or, as they are also called, asbestos-cement pipes, have always been considered a reliable and, most importantly, economical product, widely used in rural areas, in holiday villages for chimney pipes. In addition to this, products made from this material are widely used in construction: for example, sewer communications and the most famous - slate. But it's not a secret for anyone that slate bursts during a fire, however, this does not stop craftsmen from using asbestos pipes for chimneys. Meanwhile, this aspect is regulated by a number of regulatory documents.
The fire safety regulations strictly prohibit the use of such material for arranging stove heating. While building codes allow the use of asbestos, provided that the temperature of the incoming gases is not more than 300 degrees Celsius. At the same time, when passing through the attic, asbestos pipes must be insulated to prevent condensation.
And although manufacturers indicate in the technical specifications of asbestos-cement products that they can be used for ventilation openings, chimneys and gas ducts,air ducts, the operation of this material, in the presence of a furnace, can easily lead to very disastrous results. Please note that any attempt to make a chimney with this material on a wood burning fireplace or charcoal stove will result in a fire hazard, in simple terms, a fire.
When used for chimneys, an asbestos pipe shows all the shortcomings of this material, more precisely, their unsuitability for use where there is a possibility of very high temperatures.
Firstly, the use of asbestos-cement material greatly reduces traction, since there is not enough heat capacity to support it, condensate is absorbed, and only a vertical gas outlet is possible.
Secondly, there is no way to build special hatches for the revision and cleaning of soot from the chimney, which, you see, is important when using the stove for a long time. When designing, it was calculated that asbestos pipes would be used for low-power devices - gas water heaters and gas heating with a low temperature regime.
Summarizing the above, we can conclude: the use of this material is not intended for chimney in furnace heating systems, and sooner or later will lead to an accident. Alternatively, it may be a burst pipe, and, as a result, the release of carbon monoxide through the resulting crack. Adjacent flammable material may ignite.
Today the construction industry canto offer the consumer enough safe materials that allow residents of private homes not to play "Russian roulette", instead create absolutely safe and regulated conditions for the use of heating systems.
Therefore, before you buy asbestos pipes and use them for chimneys, think 100 times whether it is worth it.
