Buttweld fitting:Butt Weld CAP
Basically a cap will be applied, to shut down the end of a pipe. The Cap, as it is shown in the image below, is available for all pipe dimensions, and is sometimes also used for other purposes.End Caps are used for blocking off or sealing the end of a pipeline. The end cap is welded on at its weld prep to the relevant sized pipe within the pipeline that requires blocking off/sealing. Once in place, unlike a blind flange that can be unbolted to allow access to the pipeline, the end cap is firmly fixed.
