With a product tested to 5 million cycles, the Continental Disc HPX bursting disc will be there to do its job – to protect. You can rest at ease knowing that if it comes down to that moment, the disc will be there to perform that one final act. It’s tested. It’s proven.

The HPX Bursting Disc (Rupture Disc) is a semicircular scored reverse acting bursting disc that is ideal for liquid or gas / vapour applications. Each lot of rupture (bursting) discs is built to order per the specifications of each overpressure relief requirement in your plant. Each lot is then performance tested to provide reliable performance in your plant during normal operations and in overpressure conditions. Each HPX Bursting Disc (Rupture Disc) is proof pressure-tested prior to 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 Bursting (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 Bursting (Rupture) Discs makes future modifications to specifications easier to incorporate in change control procedures and without piping modifications.

The HPX Bursting (Rupture) Disc can be used in a wide range of applications in many different industries:

  • CHEMICAL // Reactors, Heat Exchangers, Chillers, Relief Valve Isolation
  • OIL & GAS // Distillation Columns, Separators, Coking Drums
  • PHARMACEUTICAL // Production Vessels, Blending and Milling Vessels

Emergency-Relief-Valve-Pilot-Operated-2500a  Assentech- Geodesic Dome Installation

Assentech were subcontracted to assemble and install a 25m geodesic dome for Shaft G on the Lee Tunnel project. My experience with Assentech from pre-contract through to assembly has been very positive. Unlike other subcontractors I have experienced on this project, Assentech had a very positive attitude to producing the level of documentation required for a project of this scale. Leading to a high quality pre construction packaged approved in a timely manner. The communication regarding the manufacturing process was first class allowing us to easily plan our works and prepare the site. Dome assembly was carried out very efficiently and completed to programme. The task was correctly resourced and well supervised. The work force had a positive attitude and carried out the task safely. In summary from my perspective it has been a very easy subcontract to manage with a high quality finished product.
