Fireclay pipes – ceramic pipes for the chimney
No modern chimney system can do without a fireclay pipe. Our isostatically pressed ceramic pipes are high-performance, high-tech state-of-the-art products.
Fireclay pipes form the inner layer of high-quality chimney systems and are in direct contact with the flues. Therefore, the ceramic raw materials and the production process must meet very high standards: a fireclay pipe must be able to resist low as well as high temperatures and be resistant to acid and moisture.
Isostatically pressed fireclay sleeve pipes
The highly-specialised fireclay pipe production process used for the OSMOTEC chimney systems is markedly different from traditional production methods. Isostatic pressing allows the production of extremely thin-walled ceramic pipes which are completely sealed and resistant to acids and condensates created during the combustion process.
A wall thickness of only 8 mm and a length of 66 cm make our fireclay pipes lighter, longer, and safer than traditional ceramic pipes. The 3 cm sleeve forms a perfect connection between the pipes and, together with our acid-resistant mastic, guarantees a homogenous and sealed pipe column.
Condensing solid biomass fuels such as pellets, wood chips, or grains and all fireplaces using them require chimney systems with a W3G certificate. The name “W3G” refers to the fact that the flue system has been tested and that it guarantees a sealed pipe column even in the case of a soot fire or condensate accumulation.
The isostatically pressed fireclay pipes used in our OSMOTEC chimney systems can withstand even the most extreme conditions. They are moisture-resistant (even after a soot fire) as well as resistant to temperature fluctuations and corrosion and therefore suitable for all fuel types. All these features mean that they meet the W3G certificate stipulations.
