Continental Disc HPX Rupture Disc Family
HPX-PT Pre-Torqued Holder
HPX-PT Pre-Torqued Holder
A rupture disc holder with high-strength steel socket head cap screws to ensure accurate loading and sealing of HPX rupture discs.
Optimize flow, secure seals, ensure proper disc orientation and prevent disc fragmentation with an HPX-PT pre-torqued holder. The HPX-PT holder allows the disc to be correctly fitted in the workshop using recommended torque levels prior to installation of the complete assembly between the flanges in the process system relief stream.
Get consistently accurate rupture disc installation with the HPX-PT pre-torqued holder.
Prior to installation, you’ll install and fit the disc in your workshop. Then all you need to do is complete the assembly between the flanges in the process system relief stream.
The HPX-PT pre-torqued holder incorporates high-strength steel socket-head cap screws for accurate loading and sealing of the rupture disc.
HPX-PT Pre-Torqued Holder
The HPX-PT pre-torqued holder:
Allows a precise torque load to be applied in the controlled environment of a workshop prior to installation, simplifying final installation
Maintains precise loading of the rupture disc, even where poor flange alignment and gasket cold flow may be an issue, improving performance
Pre-torqued holder screws are protected with coating to prevent wear, corrosion, sticking and galling of the screws, reducing maintenance costs
Common installations
Process equipment with glass or fluoropolymer-lined flanges that can’t provide enough compression to seal the rupture disc in the holder
Where piping arrangements restrict access, preventing correct torque loading of the flange fasteners
Processes requiring regular removal and inspection of the rupture disc and holder assembly
Applications requiring leak testing of the rupture disc assembly prior to installation in the piping system
Available options
Alternate height
Gauge taps in holder outlet
Flange studs and nuts, alloy steel or 316 SS
J-hook on holder inlet
Enhanced corrosion resistance from fluoropolymer coatings or TANTALINE treatment
Please note that pre-torqued holder designs may vary depending on bolting class and size.
