HPX-CTG™ Rupture Disc

The Continental Disc HPX-CTG™ cartridge rupture disc addresses the need to minimize potential leak paths in chemical applications. The welded rupture disc cartridge assembly, built with HPX® technology, seamlessly integrates between traditional flange connections. By eliminating the need for a separate holder, the welded design significantly reduces the risk of leaks compared to conventional rupture disc systems.

As a seal-welded version of our HPX rupture disc, the HPX-CTG ensures a leak-tight assembly, making it ideal for applications involving toxic or hazardous media or where emissions regulations are a concern. With the proven durability of the HPX rupture disc — type tested to five million cycles — the HPX-CTG enhances safety and reliability while minimizing emissions risks in critical applications.

The single-piece HPX-CTG assembly simplifies installation and minimizes the risk of damaging the rupture disc during installation and handling. Its fully welded design eliminates torque sensitivity, alleviating concerns about inconsistent torque application and the higher torque required for certain gaskets, ensuring a more reliable and flexible installation.

HPX-CTG™ Rupture Disc
  • Welded, 1-piece design improves ease-of-installation and protects rupture disc from damage due to mishandling
  • High performance operating ratio capabilities up to 95% of burst pressure
  • Broad range of burst ratings from 10 psig thru 1400 psig
  • Wide range of materials available to meet your process needs
  • Ideal for batch process run facilities with frequent operating condition and media changes
  • The versatility offered by the HPX makes future modifications to specifications easier to incorporate in change-control procedures with no piping modifications necessary
  • Safety ratio of 1 to 1 – if the rupture disc is damaged, it will relieve at or below the burst pressure
  • Rupture disc can be operated to full vacuum
  • Hermetically seal welded assembly, process side helium leak checked to 1 x 10-9 cc-atm/sec (assemblies with gage taps in inlet are checked to 1 x 10-8 cc-atm/sec)
  • Assembly eliminates the risk of improper disc installation in the holder
  • Welded design supports usage of recommended torque rates from mating gaskets
