Technical Data

Each lot of rupture discs is built to order per the specifications of each over-pressure relief requirement in your plant. Each lot is then performance tested to provide reliable performance in your plant during normal operations and over-pressure conditions. Each HPX Rupture Disc is proof pressure-tested before 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.
