Benefit of Material to Systems Application

Almost all fire protection systems use carbon steel, but the use of copper in fire protection systems is becoming more popular due to environments that require the corrosion-resistant characteristics of copper and simple cosmetic preference.

Although the initial installed cost of copper will be higher than for carbon steel fire protection piping, its longevity, and prevention of capacity loss should outweigh the cost. The need to oversize piping to compensate for scale build up and reduced flow from internal corrosion is eliminated when copper tubing is used. The NFPA 13 approved the use of 3/4 –inch copper tube in applications in which the minimum size requirement for steel is 1 inch.  Also the smoother internal surface of the pipe provides less frictional resistance than steel pipe. With increased flow capabilities, copper tubing will allow an increase in the permitted number of sprinklers on 2" and larger piping.

In addition copper tubing will not deteriorate or become brittle over time and will not burn or support combustion.

System Application and Material Usage

Copper’s rigidity and light weight allow fewer hangers and supports to be used than for plastic piping systems. In addition to this no special hold downs are needed to maintain alignment under pressurized conditions.

Copper tubing has a wide variety of sizes to meet the many applications; Type K, L, and M, hard temper copper tubing has been approved by NFPA 13 for use fire protection systems. Joints may be soldered, brazed, roll grooved for use with a mechanical coupling, flanged, or other mechanical joining methods. Brazed joints are required for most applications however soldered joints using ASTM 32 Alloy Sb5 are acceptable for certain occupancy and hazard conditions.
