CDC Forward Acting Rupture Discs

Continental Disk Logo


Tension type or forward acting rupture discs are oriented in a system with the process media pressure against the concave side of the disc. As the process pressure increases beyond the allowable operating pressure, the rupture disc starts to grow. This growth will continue as the pressure increases, until the tensile strength of the material is reached and rupture occurs. Continental Disc Corporation offers a variety of tension acting rupture discs.

A versatile, flat-seat, composite rupture disc that can act as an environmental seal, corrosion barrier, or isolate the downstream side of low-pressure storage vessels.

The ENVIRO-SEAL is composed of a metallic top section and a non-metallic seal. Depending on which design you need, the seal could be on the process side, on both the process and the vent side, or between two metallic top sections. The ENVIRO-SEAL installs between standard bore ASME, DIN or JIS companion flanges.

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
