What materials are acceptable for fire pump and jockey pump pressure sensing lines?

Brass and rigid copper are widely accepted materials for fire pump and jockey pump pressure sensing lines due to their durability, resistance to corrosion, and ability to withstand the high pressures typically encountered in fire protection systems. These materials provide reliable performance in both high and low-temperature environments, ensure consistent pressure readings, and are compliant with relevant building codes and standards for fire protection systems.

Additionally, brass has excellent mechanical properties, making it suitable for fittings and connections, while rigid copper offers good conductivity and resistance to various elements that can be present in a fire protection system. Using these materials ensures that the pressure sensing lines maintain integrity and functionality, which is crucial for the operation of fire pumps and jockey pumps.

Other materials mentioned might not meet the necessary requirements for pressure sensing applications in fire protection systems, either due to susceptibility to corrosion, lack of durability, or incompatibility with fire protection fluids.
