Continental Disc Corporation - A Cut Above the Rest

		Tension type rupture discs are oriented in a system with the process media pressure against the concave side of the rupture disc. As the process pressure increases beyond the allowable operating pressure the tensile strength of the material is reached and rupture occurs.

		Reverse Acting rupture discs are oriented in a system with the process media pressure against the convex side of the disc, placing the rupture disc in compression. As the burst pressure rating of the disc is reached, the compression loading on the rupture disc causes it to reverse, snapping through the neutral position and causing it to open by a predetermined scoring pattern or knife blade penetration.

		Sanitary Fitting Assemblies and SANITRX® Rupture Discs are specifically suited for a wide range of process applications where product purity and corrosion resistance are required. The CAL-VAC® and POS-A-SET® rupture discs are highly accurate relief devices for ultra low pressure situations.

		The state-of-the-art B.D.I. Alarm System is designed specifically for use with C.D.C. rupture discs or vent panels. The B.D.I. Alarm System consists of an alarm strip, interfaced with a monitoring unit, computer, annunciator panel, control panel or other equipment. The alarm system is activated by the opening of a rupture disc or vent panel.

		Solving pressure relief problems for you is the special role played by C.D.C.'s Product Development Group and the Special Products Group. This pool of product development expertise has been retrofitting C.D.C. designs into clients' systems for a quarter of a century. They are engineers who are at home with special or exotic materials, ultra high or ultra low burst pressures, as well as state-ofthe-art processing and testing requirements.
