Here are some common applications where specific fire protection system fittings are used:
Sprinkler systems
Tees, elbows, crosses, couplings connect sprinkler heads to branch lines and mains.
Standpipe systems
Valves, hose connections, siamese fittings allow fire hoses to access water supply.
Fire pumps
Piping from water source to pumps to boost pressure; also to hydrants & sprinklers.
Fire hydrants
Connect hydrants exterior/interior systems; caps, outlets fight fires via hoses.
Fire department connections
External hydrant-style connections for firefighter hoses.
Fire water tanks
Valves, pipes connect elevated/underground tanks as water sources.
Fire sprinkler testing
Test headers, test valves isolate sections undergoing hydro tests.
Fire alarm valves
Supervisory signal interrupts waterflow if alarm is triggered.
Foam systems
Specialty fittings inject foam solution into piping to fight class B fires.
Gaseous suppression
Pipes, nozzles disperse clean agents like FM-200 into protected areas.
Fittings enable all essential components to efficiently deliver water or suppressants as needed to effectively extinguish fires and protect lives and property.
