3 Flat Spray Nozzle Model No.7010 Size ½ to 1 NPT Flat Type The GPE tank cooling water spray nozzles are designed to produce wide angle flat spraying flows and are available in a wide range of bore sizes and materials. The 7000 series is ideally suited to the protection of storage tank shells and roofs and is widely used in process plant to protect equipment and structural members from the damaging effect of heat. The nozzle is also particularly effective in applications where a water screen is required to isolate a risk and to prevent the spread of fire or to protect escaping personnel from radiated heat. Minimizing the flow rate of spray nozzle: The minimum flow rate of each spray nozzle with any K-factor is determined with following equation: Flow (LPM) = K-Factor P =Minimum pressure = 1 BARG. (Recommended) The range of pressure = 1 to 6 BARG. 90

4 Directional Spray Nozzle Model No.7020 Medium Velocity Water spray Size ½ to1 NPT The Model 7020 spray nozzles are open (non-automatic) directional spray nozzles and are designed for use in water spray fixed systems for fire protection applications. They are external deflector type nozzles that discharge a uniformly filled cone of medium velocity water droplets. The 7020 Nozzles are effective in covering exposed vertical, horizontal, curved, and irregular shaped surfaces in a cooling spray to prevent excessive absorption of heat from an external fire and possible structural damage or spread of fire to the protected equipment. The Type 7020 nozzles are available in a wide variety of orifice sizes and spray angles (included angle of discharge) to provide versatility in system design. These spray nozzles are using in off-shore platforms, Refineries, Power Station, LPG & LNG Plants, Spherical Tanks Minimum Flow Rate of Spray Nozzle: The minimum flow rate of each spray nozzle with different K-Factor determined with following equation: Flow (Lpm) = K-Factor P =Minimum pressure = 1 Barg. (Recommended) The range of pressure = 1.0 to 5.0 Barg. Recommended Pressure 1.5 to 3.5 Barg. A= Spray Angle D =Spray Distance from wall side Theoretical Coverage Distance = (2 D) tan(a) B=Wet acoverage Distance = 0.8(2 D) tan(a) 91
