| |Copper is the most preferred option for hydraulically calculated fire sprinkler systems due to the following unique properties of copper :
Superior Flow Characteristics
- Copper Prevents Capacity Loss and Maximizes System Life: Copper's resistance to corrosion reduces scaling of tubing's inner surface. Oversizing of piping is not required to compensate for diminished flow capacity, as is required in steel pipe systems in which corrosion buildup restricts flow as systems age
- Copper has another advantage as the measurement of a tube's internal diameter remains constant throughout its life span. The oxide film, which naturally forms on the tubes inner surface does not flake off, instead acts as a protective barrier. In copper sprinkler clogging of components heads and small-diameter branch lines due to flaking is non-existent. Hence there is a reduction in periodic maintenance flushing operations.
