Tension or Reverse-Acting rupture discs?  

What is the difference between tension type and reverse acting rupture discs? We’ll get to the bottom of this frequently asked question about Continental Disc Corporation rupture discs. The key is the orientation of the process media to the disc. 

Tension type rupture discs 

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

Reverse Acting type rupture discs 

Reverse acting type 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, causing it to open by a predetermined scoring pattern or knife blade penetration.
