The condition of nozzles is essential to extinguishing fire in case of an emergency.
Blocked, damaged or incorrectly installed nozzles will prevent your deluge system from operating as designed. SIRON Fire Protection Services personnel can visually inspect all nozzles on site and replace
them if necessary.
For both piping and nozzle inspection a complete summary will be provided on marked up isometric drawings highlighting the location of problem areas.

Over time, especially in areas susceptible to high volumes of work scopes, SIRON has repeatedly found damaged or incorrectly installed nozzles.
Due to the hydraulic design requirements being different for each deluge system there are 100’s of different types of deluge nozzles available with different parameters including:
- Medium Velocity Nozzles
- High Velocity Nozzles
- Various Spray Angles
- Various Orifice Sizes
- Various Thread Connection Sizes
Each deluge system
when it is t the design phase pre construction is designed on a computer and a hydraulic calculation is run.
The hydraulic calculation is important as it gives the designer the correct information on such items as:
- Number of nozzles required to ensure sufficient fire water coverage to the protected areas
- Hydraulic balance of each deluge system to prevent water hammer
- Size of each nozzle orifice
- Spray angle of each nozzle
- Fire water demand (flow and pressure) of each deluge system through each deluge valve
This then allows the deluge system to be installed correctly and ensures that the protected area has enough fire water to maintain a constant density application rate across the area and will operate as designed to protect personnel and infrastructure.
Over time it is common for nozzles to be damaged during routine maintenance or activities in the local area. If a nozzle is damaged, or if a new but incorrect nozzle is installed then this will have an adverse effect on the hydraulic model and also density application flow rates, subsequently increasing risk to plant and personnel.
