Forged Threaded Union
The Forged Threaded Union is a three-piece fitting that creates a fully demountable joint in a threaded piping system. Both pipe ends are screwed permanently into the two end pieces (male end and female end), each carrying female NPT pipe threads. The central hex union nut threads onto the female end piece and draws both end pieces together, compressing their precision-machined ground joint faces to create a metal-to-metal pressure seal without any gasket or sealant tape at the joint face.
To break the joint, the union nut is unscrewed, releasing both end pieces and allowing the piping on either side to be separated freely without rotating the pipe. This makes the threaded union the standard demountable connection for equipment isolation, maintenance access and future tie-in points in screwed piping systems. Cunimet Alloy International supplies all three pieces as a matched set machined from the same material grade.
