Fire Cooling Sprinkler System
Precise Adaptability: Specializes in steel cylindrical tanks and spherical tanks in the petrochemical industry, addressing the key issues of cooling under high temperatures and medium loss.
Dual Effects of Cooling and Fire Suppression: Forms a water curtain or water mist, taking into account daily protection and emergency fire suppression.
Stable and Durable: Core components are made of hot-dip galvanized material, featuring corrosion resistance and aging resistance, ensuring a long service life.
Easy Installation, Operation and Maintenance: Factory-prefabricated and installed with U-bolt fixing. With highly standardized components, it allows for simple inspection and maintenance.
Efficient Loss Control: Reduces the diurnal temperature difference of the medium, minimizes the "standing losses" (small breathing losses) of storage tanks, and helps enterprises cut costs.
Product Introduction
The Fire Sprinkler is a dedicated water cooling and temperature reduction facility for steel storage tanks (cylindrical tanks or spherical tanks) in petroleum and chemical enterprises. As a core component of the Fire Sprinkler System, it accurately meets the safety protection needs of industrial storage tanks. In high-temperature environments during summer, this device can continuously and evenly spray water to cool the storage tanks. The cooling water flows down evenly from the top of the tank along the tank wall, efficiently reducing the solar radiation heat absorbed by the tank, minimizing temperature fluctuations in the tank's gas space, and narrowing the diurnal temperature difference of the stored medium. Thereby, it significantly reduces the "small breathing" loss of the tank and helps enterprises control material waste and cost expenses.
Our company's series of tank fire cooling sprinkler products are a set of core equipment for the Fire Sprinkler System that are fully factory-prefabricated. The product mainly consists of hot-dip galvanized water spray ring pipes, water curtain nozzles, water supply risers, restrictor orifices, metal hoses, filters, and control valves. It is fixed on the positioning bracket of the storage tank via U-shaped clamps and can spray water curtains or water mist at preset angles and flow rates to the protected object. It has the dual functions of cooling and emergency fire suppression, providing comprehensive protection for the safety of storage tanks.
Product Applications
Petrochemical Industry：It is applicable to various types of storage tanks such as steel cylindrical tanks and spherical tanks. It is used for cooling and temperature reduction, reducing medium loss, and also has the function of fire suppression.
Industrial Buildings：Including workshops, warehouses, etc. In case of fire, it can automatically spray water to extinguish the fire, ensuring the safety of personnel and property.
Commercial Buildings：Such as public places like shopping malls, office buildings, hotels, etc. It provides fire protection for densely populated areas.
Civil Buildings: Including high-rise residential buildings, apartments, etc. It is used for fire suppression in the early stage of fire and guaranteeing personnel evacuation.
