Stainless Steel Deluge Valve Manufacturers

1. 304 Stainless Steel:

Suitable for mild corrosive environments, in such scenarios, the concentration of corrosive media is low and the affected area is small. The anti-corrosion performance of 304 stainless steel is sufficient to meet the requirements. For example, in the acid washing workshop and fermentation workshop of food processing plants, small amounts of acid and alkali vapors are produced during the production process. The 304 stainless steel alarm valve can resist steam corrosion and also complies with the hygiene standards of the food industry, without polluting the production environment. Although the data center computer room has a dry environment, the precision equipment has extremely low tolerance for the failure of the fire protection system. The 304 stainless steel has no rusting risk and can reduce the frequency of equipment maintenance, avoiding the paralysis of the fire protection system in the data center due to the failure of the alarm valve. In addition, in places such as the clean area of the pharmaceutical factory and the assembly workshop of the electronic component factory, 304 stainless steel alarm valves are also often selected, taking into account both the anti-corrosion and cleanliness requirements.

2. 316/316L Stainless Steel:

Designed specifically for highly corrosive environments, it is the preferred material for high-risk scenarios such as coastal areas and chemical industries. The open-air fire protection systems in coastal ports are constantly exposed to salt fog for long periods. Ordinary materials will corrode and fail within 1-2 years. The molybdenum element in 316L stainless steel can form a denser oxide protective film, preventing chloride ions from penetrating, and it can be used stably for over 15 years. In chemical industrial parks, the production and storage areas, as well as some areas with slight medium leakage, 316/316L stainless steel can withstand these corrosive media and ensure that the alarm valve operates reliably during a fire. In salt chemical enterprises' salt production workshops and seawater desalination plants, the fire protection systems directly use seawater with high chloride ion content as the fire water source. 316L stainless steel is the only material that can withstand long-term seawater erosion, avoiding valve body corrosion perforation and resulting in fire water leakage. In addition, the fire protection systems of offshore drilling platforms and near-sea vessels must also use 316L stainless steel alarm valves to cope with the strong corrosion challenges of the marine environment.
