A threaded half coupling means a steel coupling which only has one thread end, another end of the coupling should be butt welding end. The thread end could be NPT or BSP standard thread. The butt welding end could be a plain end or a bevel end. it could be the connection between a pipe of male thread end and a pipe of no thread end.
When installing this coupling in site, the ends should be in correct direction.
