How to choose stainless steel ventilation pipes suitable for fire fighting engineering?

The selection of stainless steel ventilation pipes suitable for fire fighting engineering needs to be comprehensively considered from the material, specification, performance, quality and other aspects. The following are the specific points:

Material aspect

Stainless steel type

304 stainless steel: It has good corrosion resistance, heat resistance and rust resistance, can withstand the high temperature caused by general fires, and the price is relatively reasonable, so it is a commonly used material in fire fighting engineering.

316 stainless steel: Molybdenum is added on the basis of 304, which has stronger corrosion resistance, especially higher tolerance to chloride, etc. It is suitable for some fire-fighting and ventilation places where the environment is harsh and may come into contact with corrosive substances, such as buildings near the seaside or chemical areas.

Material purity: ensure the purity and quality of stainless steel, and avoid the influence of excessive impurities on the performance of the pipeline. The supplier may be required to provide a material inspection report to check whether the contents of main elements such as chromium, nickel and molybdenum meet the standard requirements.
