Which term describes pipes or joints that connect sprinkler heads and other system components?

The term that best describes pipes or joints that connect sprinkler heads and other system components is fittings. In fire sprinkler systems, fittings are essential components designed to connect different sections of piping and provide the necessary transitions, such as elbows, tees, and couplings. The design and construction of fittings ensure that the sprinkler system operates effectively and maintains its integrity under varying pressures and conditions.

Fittings play a crucial role in maintaining proper water flow and pressure throughout the system. They must be compatible with the piping materials used and compliant with the standards outlined in NFPA 13 to ensure reliability and safety in fire suppression efforts. Understanding the function of fittings helps in selecting the right components for a sprinkler system installation, ensuring that all parts work together seamlessly to protect property and lives effectively.
