IS 2871:2012 is the Indian Standard (BIS) for branch pipe, universal for fire fighting purpose- specification. 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.

Frequently Asked Questions3
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.
