Pretorqued holder ensures accurate loading and sealing
HPX-PT pretorqued holders from Continental Disc incorporate high-strength steel socket head cap screws to ensure accurate loading and sealing of the HPX rupture disc. The HPX-PT pretorqued holder allows the disc to be correctly fitted in the workshop using precise recommended torque levels before the complete assembly is installed between the flanges in the process-system relief stream.
The unit’s cap screws maintain a seal between the holder and rupture disc to prevent the disc from slipping or leaking in the holder after it is removed from the vessel nozzle or pipe flange for inspection. Once the disc has been inspected, the holder and disc may be reinstalled.
In addition, the HPX-PT pretorqued holder has a durable, tapered seating surface designed to prevent rupture disc slippage and to provide a bubble-tight seal over various HPX rupture disc sizes, materials, and burst ratings. The HPX-PT pretorqued holder is appropriate for active-ingredient processing plants and fill–finish plants that require sanitary connections and environments.
