What role does Suzhou stainless steel welded air duct play in fire fighting engineering?

Suzhou stainless steel welded air duct has the following main functions in fire fighting engineering:

Smoke extraction

Smoke exhaust: When a fire breaks out, a large amount of smoke will be generated. As a key part of the smoke exhaust system, the stainless steel welded air duct can quickly exhaust the smoke outside the building, reduce the smoke concentration, create a clear vision for personnel evacuation and fire rescue, and reduce the harm of smoke to personnel. For example, in the fire protection design of high-rise buildings, by reasonably arranging the stainless steel welded air duct, the smoke on each floor can be quickly guided to the outside.

Prevention of smoke accumulation: it can effectively prevent smoke from accumulating in corridors, stairwells, elevator shafts and other passages inside buildings, avoid people being disoriented due to smoke, ensure the safety of evacuation passages, and enable people to evacuate the fire site more quickly and safely.

Ventilation

Providing fresh air: In the process of fire rescue, providing necessary fresh air for the interior of the building, maintaining a certain air circulation and ensuring that trapped people and firefighters have enough oxygen supply will help improve their survival chances and work efficiency, and gain more time for rescue work.

Balanced air pressure: it helps to balance the air pressure inside and outside the building, prevent the air pressure difference caused by fire from damaging the building structure, or affect the normal work of fire-fighting facilities such as fire doors and fire shutters, and ensure the overall stability of the fire-fighting system.

buffer action

Prevent the fire from spreading: Stainless steel has good fire resistance, which can prevent the fire from spreading to other areas through air ducts to some extent, and play a role in fire separation. For example, setting stainless steel welded air ducts between different fire zones of a building can effectively prevent the fire from spreading from one zone to another.

Blocking the spread of harmful gases: The toxic and harmful gases generated by fire can be confined to a certain range and discharged outside through the air duct to avoid their wide spread in the building and protect the safety of people in areas not affected by fire.

Ensure the operation of fire fighting equipment

Heat dissipation for fire-fighting equipment: some fire-fighting equipment will generate heat during operation. Stainless steel welded air duct can be used as a heat dissipation channel to discharge heat, so as to ensure the normal operation of fire-fighting equipment at a suitable temperature, improve the reliability and service life of fire-fighting equipment, and ensure that it can play its due role in fire.

Provide access for smoke control equipment: connect with fire-fighting smoke control fans and other equipment, and provide access for conveying air and smoke for these equipment, so that the smoke control system can operate normally and realize efficient smoke control and ventilation functions.
