Chimney pipe DN 100, L=250 for boilers with open combustion chamber SJBRP250100

Application and corrosion resistance

This component of the ventilation and exhaust system has been designed for use in open combustion chamber boilers, where exhaust gas temperature and chemical aggressiveness require specialized materials. Unlike standard steel pipes, this model is made of acid-resistant sheet metal. This is a key difference that directly translates into the service life of the installation. The acidity of exhaust gases, especially in oil or gas boilers with lower return temperatures, can quickly destroy ordinary stainless steel. Here, the material provides resistance, meaning the pipe will not undergo rapid perforation or corrosion in areas exposed to acid condensate. As a result, the installation maintains tightness for many years, and the risk of exhaust gases entering the room is minimized.

Construction and mounting dimensions

The primary dimension of this pipe is the nominal diameter DN 100, making it a universal component suitable for most standard single-function and dual-function open combustion chamber boilers. The segment length is 250 mm, which is an optimal value for creating compact passages through ceilings or connecting with other system elements without the need for additional reducing adapters. The sheet thickness and manufacturing method ensure structural rigidity, facilitating installation even in hard-to-reach places in attics or masonry chimneys.

For installers, it is important that this pipe:

• Easily connects with other system elements of 100 mm diameter;
• Does not require additional thermal insulation inside the duct itself (although external insulation may be necessary according to the design);
• Is ready for immediate installation upon removal from the packaging – no additional material processing required.

Compliance and operating conditions

The product meets the requirements set for materials used in exhaust installations for gas and oil boilers. Its use guarantees operational safety in accordance with standards regarding exhaust gas discharge. It is worth noting that this pipe is intended exclusively for open combustion chamber systems – it is not suitable for closed combustion chamber (turbo) boilers, where different material and structural solutions are required due to the pressure in the system.

By choosing this component, you receive a product that not only fulfills the function of conducting exhaust gases but, above all, protects the investment against premature material wear caused by chemical factors occurring during the combustion process of fossil fuels.
