FO R STANDARD O R COM POSI TE T Y P E RU PT URE DISCS FLEXIBILITY OF USE IN TIGHT PIPING CONFIGURATIONS The Union Holder is designed to provide flexibility of use in tight piping configurations. These procisely built holders combine ease of installation with high pressure ratings in pipe sizes of 2 inches (50 mm) or less. Standard sizes, ratings and bores are shown in Table I. Contact your representative for applications outside this range. SPECIFICATIONS Union Holders are designed for standard or composite type rupture discs. Any combination of welded or threaded inlet and outlet connections is available. All parts are available in carbon steel or 316 SS. The units are designed with 30° angular seating. Refer to the Continental Disc Industrial Product Selection Guide for rupture disc details. Muffled plugs can be supplied for use with Union Holders with threaded outlets to reduce reaction forces upon burst of the rupture disc. PRODUCT IDENTIFICATION As a standard, rupture discs for use in Union Type Holders are shipped with a detached tag, which should be affixed to the completed assembly when the rupture disc is installed. Under certain circumstances, such an installation may comply with the ASME Code. See ASME code case no. 2367. For those requiring ASME compliance or simple, positive identification of rupture disc installations, Continental Disc offers a special Union Type Holder which allows the installation of a rupture disc with a permanently attached 3-dimensional flow direction tag. The 3-D flow tag extends beyond the holder for easier verification of orientation after the rupture disc has been installed. When ordering rupture discs, please state whether the disc is to be installed in a Union Holder, and whether you require the standard configuration or a permanently attached 3-D flow tag.
