Threaded steel pipes are connected using threaded pipe fittings such as couplings, threaded elbows, threaded reducers, threaded tees, and threaded flanges. These materials are preferred in fire sprinkler systems and are manufactured with a red primer coating.
They are UL & FM certified for use in fire protection systems. Couplings not only securely join these elements but also provide leak-proof sealing, playing a critical role in vital systems such as sprinkler lines. The threads on the threaded steel pipe and connection parts allow the coupling to grip tightly onto these threads, ensuring a secure connection. Since welding is not required during installation, the process is fast, safe, and easy.
