Black Steel Chimney Pipes (2 mm) for Connecting Stoves and Fireplaces

Thick-walled black steel chimney pipes are designed for connecting wood-burning and sauna stoves, fireplaces, and boilers to the main chimney. These elements are installed indoors and serve as the initial section of the smoke extraction system. They connect directly to the heating appliance's outlet nozzle and ensure a safe connection to the main chimney — be it an existing brick, ceramic, or insulated stainless steel one.
Akvilon products are manufactured in Latvia, comply with the European standard EN 1856-2, have CE marking and fire safety class G, which confirms their resistance to soot fire and safe operation with solid fuel appliances.
Key Advantages:
- High Quality: Our thick-walled chimney pipes and all accompanying connections are made of durable 2 mm black steel. This ensures excellent mechanical strength, resistance to deformation, high temperatures, and aggressive flue gases. This ensures reliability, safety, and a long service life for the entire system.
- High Heat Output: Steel elements additionally heat the room, increasing the efficiency of the heating system.
- Precision TIG Welding: Reliable welding of longitudinal seams ensures airtightness, operational safety and a long service life.
- High Heat Resistance: The chimneys comply with temperature class T600 and are coated with heat-resistant Senotherm paint, which withstands up to +600 °C. The coating does not emit smoke or unpleasant odors, protects against corrosion, and extends the durability of the entire installation.
- Easy Installation: The plain-end slip-fit connection principle makes chimney installation easy and fast.
- Assortment and Availability: A wide selection of chimney elements of various sizes is available, allowing you to choose the optimal solution for various installation needs and ensure quick dispatch.
- Direct from Manufacturer Prices: You buy directly from the manufacturer, which guarantees no intermediary markups and best prices, as well as direct support and consultations from Akvilon specialists.
