What is the standard hydraulic test pressure for universal branch pipes?

Every branch pipe must withstand a hydraulic pressure of 2.1 MPa (21 kgf/cm²) for 2.5 minutes without any sign of leakage or sweating.

What operational modes must a universal branch pipe have?

It must provide a straight solid jet, an umbrella spray (curtain), and a complete shut-off capability.

What type of inlet connection does it use?

It typically uses a standard 63 mm instantaneous male coupling conforming to IS 903.

This standard prescribes the requirements for materials, dimensions, construction, and performance testing of universal branch pipes used for firefighting. Universal branch pipes allow firefighters to switch seamlessly between delivering a solid water jet, creating an umbrella spray (water curtain) for heat protection, or completely shutting off the flow.

Practical Notes

Ensure regular lubrication of the moving control ring to guarantee smooth transitions between jet, spray, and shut-off modes during emergencies.

For marine, coastal, or highly corrosive industrial environments, heavily prefer gunmetal or stainless steel branch pipes over aluminum alloy.

Always inspect the internal rubber washers and instantaneous coupling catch-springs to prevent leaks or detachment under high water pressure.
