Continental Disc Corporation rupture discs

Performance under pressure

As of April 16th 2018 Heleon Group has become the official distributor in Belgium and The Netherlands for the Continental Disc Corporation (CDC) range of sanitary rupture discs and associated accessories for both the pharmaceutical and food/beverage industries. Established in 1965, Continental Disc Corporation is a leading manufacturer of rupture disc (bursting disc) devices for a variety of process industries, including chemical, petrochemical, petroleum refining, pharmaceutical, food and beverage, aerospace, industrial gases, transportation, and other markets worldwide.

A rupture disc is a non-closing pressure relief device that provides immediate relief in a predetermined overpressure or vacuum condition at a specific temperature. This safety device provides instantaneous protection for systems, equipment, and vessel. Rupture discs function as a pre-designed "weak point" in a pressurized system, and they should be the strongest part of your pressure protection system. Sometimes rupture discs are used as primary protection, meaning the rupture disc alone ensures protection. In other applications, rupture discs are used together with pressure relief valves. Some rupture discs that are frequently used in pharmaceutical, biotech, food and beverage industries are available to fit between industry standard sanitary ferrules, NA-Connect® flanges or Tri-Clamp® fittings.
