Why do fire fighting projects need to install stainless steel ventilation pipes?

The need to install stainless steel ventilation pipes in fire fighting engineering is mainly based on its advantages in fire prevention performance, corrosion resistance, stability, health and environmental protection, installation and maintenance, etc. The following is a concrete analysis:

Good fire resistance

Stainless steel has a high melting point, generally around 1300℃-1400℃. When a fire occurs, it can withstand high temperature and is not easy to deform and melt, which can effectively ensure the integrity and functionality of ventilation pipes in a certain period of time and gain time for personnel evacuation and fire rescue.

Its incombustible characteristics meet the strict requirements of fire protection engineering for building materials, which can prevent the fire from spreading through the ventilation system and reduce the risk of fire spreading.

Excellent corrosion resistance

Ventilation pipes in fire fighting system may come into contact with all kinds of corrosive gases and substances. For example, the smoke generated in fire may contain acidic or alkaline components. Stainless steel ventilation pipes have good corrosion resistance, which can resist the corrosion of these substances, prolong the service life of the pipes and ensure the normal operation of the ventilation system at the critical moment of fire fighting.

In some humid environments, such as underground parking lots and fire pools, pipes made of ordinary materials are easy to rust and corrode, while stainless steel ventilation pipes can effectively resist the influence of humid air and keep the performance of pipes stable.
