The HPX® Rupture Disc (Bursting Disc) is a scored reverse acting rupture disc (bursting disc). This differential pressure relief device features an instantaneous full-open relief area for protecting equipment, vessels, systems and people from an overpressure condition. These high precision reverse acting rupture discs (bursting discs) offer proven performance in excess of 250,000 cycles at 95% operating ratio.
Each lot of rupture discs is built to order per the specifications of each overpressure relief requirement in your plant. Each lot is then performance tested to provide reliable performance in your plant during normal operations and in overpressure conditions. Each HPX Rupture Disc is proof pressure-tested prior to shipment.
Optimum material thickness and manufacturing tooling design provide not only the full opening and accurate burst rating you expect, but also longer service life at higher operating-to-burst pressure ratios demanded by today’s process industries.
Due to its high performance operating capabilities, range of burst ratings and materials of construction, the HPX Rupture Disc is the ideal product to use in plants where production includes batch processing runs where operating conditions and media may change frequently. The variability offered by HPX Rupture Discs makes future modifications to specifications easier to incorporate in change control procedures and without piping modifications.
