Fike recently added the TQ+ to its line of pretorqueable rupture disc holders. The pretorqueable holder allows rupture discs to be installed and then "torqued" to recommended static load levels, properly clamping the rupture disc within the assembly. For added convenience and to reduce the possibility of assembly errors, this can take place at a workbench, rather than in the field where conditions could be less than ideal. The TQ+ was designed with the ability to be installed in multiple international flange rating configurations, including ANSI, JIS, DIN, and ISO, making it quite versatile for a wide range of applications. The holders may also be removed, inspected, and re-installed during routine maintenance and plant turnarounds, without compromising disc performance, provided the disc is not removed.
