DonadonSDD disc holders are designed in order to ensure maximum reliability to DonadonSDD rupture discs.
HI/P and HR/P pre-tightened disc holders offer the following advantages:
Upon request, HI/P and HR/P disc holders can be verified in our laboratories and supplied pre-assembled with their own rupture discs, ready for direct insertion in the plant.
Standard DonadonSDD disc holder materials: Carbon steel, Stainless steel (316L), Alloy 201, Alloy 400, Alloy 600, Alloy C276. Special executions are available in Titanium or Tantalum or with PTFE or glass fibre reinforced PTFE lining.
Reverse acting (or compression) discs, like for example models SCR, Y90 and KRD, are installed in HR/P holders sized in order to protect the dome of the disc and allow correct opening of the disc. Therefore the size of HR/P disc holders can be larger.
