Darco - connection system for fireplaces and solid fuel boilers SPK - rectangle / circle reduction

Reduction from the system of standard round pipes to a rectangular / square cross-section.

The first parameter gives the diameter of the smoke pipe DN.

A system of pipes, elbows and SPK joints, designed for removing flue gases from the furnace and in a fireplace fired with wood or other solid fuel. Elements of the system supply exhaust gas to an existing chimney, e.g. ceramic or masonry. They meet all required Polish and European standards, ensure the necessary tightness of the cable, and thus safety and comfort.
The pipe elements in this system are welded by LASER technique, which guarantees the HIGHEST QUALITY of connections and exceptional aesthetics, which means that the pipes can remain exposed.

The material of which the chimney connections are made is black steel sheet in DC01 grade, 2mm thick. They are used as connections for flue gas from the fireplace and heating devices for solid fuels (operating without condensation), where the temperature of the flue gas can reach up to 1000 [C].
