China foam tank is a device used to store chemical foam that is used in fire fighting operations. These tanks are designed to store and preserve foam formulations that are used with water to produce foam that helps in extinguishing fires, especially fires with flammable liquids. These tanks are usually made of corrosion-resistant materials, such as stainless steel, and are equipped with mechanisms to efficiently mix the foam with the water. Foam tank is an essential part of fire fighting systems in petrochemical industries, airports and large storage facilities.
