45-Degree Flow Nozzle Elbow | 2-1/2 in. F NST x 2-1/2 in. M NST | Brass

45-Degree Flow Nozzle Elbow 2-1/2 in. FNST x 2-1/2 in. MNST

This 2-1/2 in. FNST x MNST 45-Degree Hydrant Flow Nozzle Elbow is a specialized tool used in flow testing of fire hydrants. Flow testing is conducted to measure the water flow rate and pressure available from a hydrant to assess its performance and ensure it meets the required standards. The hydrant flow nozzle is attached to the outlet of the fire hydrant, replacing the regular hydrant nozzle. This tool attaches to the standard flow nozzle and is designed to provide a 45-degree flow of water during testing. It is constructed of Cast Brass.

Canadian CSA thread options are available upon request.

Why is Hydrant Flow Testing Important?

System Performance Evaluation: Flow testing allows fire departments and water authorities to assess the performance of fire hydrants and the water distribution system. It helps identify any deficiencies, such as inadequate flow rates or insufficient pressure, which can affect firefighting operations.

Hydrant Placement and Planning: Flow testing helps determine the optimal placement and spacing of hydrants in a given area. It ensures that hydrants are strategically located to provide adequate water supply for fire suppression, considering factors like flow rates, pressure requirements, and coverage areas.

Fire Protection System Design: Flow testing provides valuable data for designing fire protection systems. It helps determine the required size of water mains, pipe networks, and pumps to ensure sufficient water supply for fire sprinkler systems, standpipe systems, or other fire suppression systems.

Compliance and Standards: Flow testing is often required by fire codes, insurance agencies, and regulatory authorities to ensure that fire hydrants meet specific standards and performance criteria. Regular flow testing helps maintain compliance and ensure the reliability of fire protection infrastructure.
