With copper's superior flow characteristics, system designers can incorporate several economies that help keep costs down:
Installation Ease and Versatility
- A reduction in cross and feed main sizing, in many hydraulically-calculated systems
- An increase in the permitted number of sprinklers for copper lines of two-inch and larger, in pipe schedule systems
- The NFPA 13-approved use of ¾-inch copper tube in applications in which the minimum size requirement for steel is 1
Copper is extremely easy to install, is cost effective and has more designing options. From initial delivery to installation, entire work can be done within a short span of time. With copper, there are no such problems of storing, delivery, handling etc., when compared with other material.
Copper's properties of ease of handling avails more options for designing and either shop or field fabrication. With the use of portable hand tools, bending, cutting and joining of copper can be accomplished in limited-space areas.
With modern tools and machinery installation cost of tee connections and outlets in copper facilitates shop or field assembly is reduced by 25%.
Copper is rigid and light weight and hence fewer hangers and supports are required when compared with other piping systems. Copper requires no special hold-downs to maintain alignment under pressure.Innovative Possibilities
Copper Permits Combining Hydronic Systems: A single copper piping loop can supply water to both sprinkler system and heat pumps. And thus saves per square foot in building costs for a combined system. Using a water-source heat pump with a sprinkler is more efficient way to obtain better fire protection at lower cost than having separate systems for heating, cooling and fire protection.
