Pipe

Fire sprinkler piping distributes water throughout the system and is primarily made from steel, CPVC or copper. Steel pipe, commonly black or galvanized, is durable and suitable for all hazard levels, including commercial, industrial, and high-rise applications. All piping for fire protection use must meet specific material specification Standards as required by the local or national Standards for that country. Steel piping can be joined by threading, welding, or grooved couplings. CPVC pipe (chlorinated polyvinyl chloride) is a lightweight, non-metallic alternative used primarily in light hazard occupancies such as residential and office settings. CPVC is joined using solvent cement and is resistant to corrosion but limited by temperature and exposure to certain chemicals. Copper tubing is typically joined to copper fittings by soldering the joints.
