ASME B16.9 Pipe Cap is used to seal an open end of the pipe. In piping engineering, the cap made in accordance with ASME B16.9 will be welded to the end and need not be included in the length dimension of the run of pipe. As their name suggests, the primary function of the Pipe Ends, or ASME B16.9 Cap, is to act as a seal to the end of a pipe. Primary function of SS End Caps is to maintain a waterproof piping network. In addition to this, the other roles of the ANSI B16.9 Pipe Cap Fittings include - to resist moisture, chemicals and weather.
