Products description

Heat-resistant elbow for connecting the wood-burning stove chimney liner.

Heat-resistant chimney liners are made of heat-resistant chromium-nickel steel sheets, grade 1.4828 according to DIN 17441, thickness 1.0 [mm]. They are mainly used to remove flue gases from wood-fired heating devices operating under negative pressure. Such chimneys are resistant to high temperatures that may arise in such a work environment. It is also possible to make a 1mm thick insert in 1.4404 sheet metal. This is justified when you need to connect a boiler for solid fuels with high efficiency, and thus - exhaust gas at a very low temperature. This sheet is not as heat resistant as grade 1.4828, but it is characterized by much greater resistance to acid in the condensate.

Advantages of heat-resistant insert

high resistance to acid, mainly sulfuric acid
resistance to high temperatures (temporarily up to 1250 C)
much lower resistance to exhaust gas flow than traditional chimneys in masonry due to less surface roughness
can be used inside buildings in newly built chimneys as well as when renovating old ones.
