Exhaust elbow 250, 90° with support 48888962

Safe flue gas discharge in large-diameter installations

This component is a key element in both gravity and mechanical ventilation systems, where precise redirection of hot gas flow at a right angle is required. With a nominal diameter of 250 mm, this component is dedicated to installations with high flow rates, commonly found in industrial boilers, large gas or oil-fired boilers, and industrial ventilation systems. The use of a 90° elbow allows for a change in draft direction without the need for complex piping arrangements, simplifying the flue gas duct route and minimizing pressure losses.

Construction with support for mounting stability

A key feature of this solution is the integrated support, which significantly increases the rigidity of the entire structure. In the case of pipes with such a large diameter as 250 mm, the metal wall alone may be insufficient to maintain stability under its own weight or vibrations generated by the boiler. This reinforcement prevents deformation and ensures that the joint remains sealed even under prolonged exposure to high temperatures.

For the installer, this means:

• Easier installation – the rigid pipe maintains its position more easily when connecting with other system components.
• Reduced susceptibility to mechanical damage during transport and construction works.
• Operational safety – the risk of settlement or duct deformation is drastically reduced.

Application and operating conditions

This product is used where standard solutions do not meet strength or geometric requirements. It is an essential element when modernizing old chimneys or constructing new flue gas discharge systems in facilities with high heat demand. The material allows operation in environments with chemically aggressive flue gases and at high temperatures.

In engineering practice, three aspects of this component are critical:

1. Large diameter (250 mm) – dedicated for high-power devices such as industrial boilers or large condensing boilers, where flue gas flow is crucial for the efficiency of the entire system.
2. 90° angle – enables efficient change of draft direction (e.g., from vertical to horizontal) while maintaining the compactness of the piping system, often required in tight technical spaces.
3. Reinforced construction – support is necessary for long pipe sections or in locations exposed to vibrations, to avoid mechanical overloads and ensure stable connections over years of operation.

It is important to remember that proper installation of such an element requires careful sealing of joints to prevent leaks that could allow flue gases to enter rooms. Thanks to its solid, reinforced construction, this component ensures system durability without the need for frequent inspections or mechanical repairs related to pipe deformation.
