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 summer cottages for chimney pipes. In addition to this, products from this material are widely used in construction: for example, sewer communications and the most famous is slate. But it is no secret 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 rules on fire safety are strictly forbidden to use such material for the arrangement of furnace heating. While building standards 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 in the technical specifications of asbestos-cement products, manufacturers indicate the possibility of their use for ventilation holes, chimneys and ducts, 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 of this material on a wood fireplace or coal stove will lead to a fire hazard situation, in simple terms, to a fire.
When used for chimneys, an asbestos pipe exhibits all the shortcomings of this material, more precisely - their unsuitability for use where there is the likelihood of a very high temperature.
Firstly, the operation 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 can be installed.
Secondly, there is no way to build special hatches for revising and cleaning soot from the chimney, which, you see, is important for prolonged use of the furnace. During the design, it was calculated that asbestos pipes would be used for low-power devices - gas water heaters and gas heating with a low temperature regime.
Summing up the foregoing, we can conclude: the use of this material is not intended for chimney in furnace heating systems, and sooner or later lead to an accident. Alternatively, it can be a burst pipe, and, as a result, the carbon monoxide exit through the formed crack. Fire may occur in an adjacent flammable material.
Today, the construction industry can offer consumers enough safe materials that prevent residents of private houses from playing Russian roulette, instead create completely safe and regulated conditions for using heating systems.
Therefore, before you buy asbestos pipes and use them for chimneys, think about it 100 times.
