This standard prescribes the requirements for materials, dimensions, workmanship, and testing of universal branch pipes used for fire fighting purposes. It specifically covers dual-purpose nozzles that allow operators to switch between a solid jet and a water spray or curtain.
Branch Pipe, Universal For Fire fighting Purpose- Specification
Quick Reference Values
standard inlet size63 mm instantaneous male
hydraulic test pressure2.1 MN/m2 (21 kgf/cm2)
hydraulic test duration2.5 minutes
Practical Notes
Universal branch pipes are critical for fire control as they allow the operator to adjust the flow pattern (jet or spray) based on the fire type and required heat shielding.
Ensure the branch pipe inlet coupling strictly conforms to the standard 63 mm instantaneous type for compatibility with standard fire hoses.
During maintenance, regularly inspect moving components and sealing washers to prevent seizing and leakage during an emergency.
