####

Fire-sprinkler systems are a fundamental component of modern fire protection strategies, offering active protection that enhances occupant safety, minimizes structural damage, and ensures compliance with building codes. When properly designed, installed, and maintained, these systems can effectively control or extinguish fires before they escalate, reducing threats to life and property. The pipe materials that comprise such systems have significant impacts on their performance and reliability, so integrating these critical life-safety systems into a building’s design requires careful consideration of factors that go beyond simply meeting applicable codes.

This report provides a comprehensive overview of system components, design considerations, and material options associated with fire-sprinkler systems. It is based on guidance from the American Society of Plumbing Engineers (ASPE), the National Fire Protection Association (NFPA), and other technical and industry sources.

System Types

Sprinkler systems fall into four categories.

• Wet pipe systems contain water at all times; individual sprinklers activate when triggered and discharge water
