SS 347 Couplings (Full, Half, & Reducing) - Pipe Fittings

SS 347 Couplings are small, threaded or socket-weld pipe forgings used primarily to connect two pipe sections or to allow for a threaded connection onto a pipe. They are commonly supplied as **Full Couplings** (threaded completely through to connect two pipes) or **Half Couplings** (threaded on one side to connect to a pipe run, with the other side being welded). Manufactured from **Niobium-stabilized austenitic stainless steel**, these fittings, supplied by **Zeron Fasteners**, are highly resistant to **intergranular corrosion** when exposed to high heat (e.g., during welding or service up to **870°C**). This stabilization is crucial for maintaining the integrity and corrosion resistance of the piping system in severe service environments like chemical processing, petrochemical refining, and power plant operations, where standard stainless steel threaded joints might fail due to thermal sensitization.
