The HPX-PT pre-torqued holders incorporate high strength steel socket head cap screws to ensure accurate loading and sealing of the HPX rupture disc. The device allows the correct fitting of the disc in the workshop using the precise recommended torque levels, prior to installation of the complete assembly between the flanges in the process system relief stream.

Common installations for the HPX-PT are process equipment with glass or Teflon lined flanges that cannot provide the compression required to seal the rupture disc in the holder. Also installations in which the piping arrangement restricts access preventing correct torque loading of the flange fasteners or processes that require a regular removal of the rupture disc and holder assembly for inspections and applications requiring leak testing of the rupture disc assembly prior to installation in the piping system.

Features of the HPX-PT include allowing a precise torque load to be applied in the controlled environment of a workshop prior to installation, and maintaining precise loading of the rupture disc where poor flange alignment and gasket cold flow may be an issue.
