GRAPHITE RUPTURE DISKS
ZOOK Graphite Rupture Disks fit directly between standard flanges without the need for additional holders.
A flow arrow on each disk indicates proper orientation.
Armor provides additional protection from extraneous stress to the disk resulting from misaligned piping. Armor is standard on selected diameter and burst ratings and is required in fire case and toxic services.
Gaskets should be ring type, non-metallic, relatively soft, and properly sized.
Normal good practice should be followed when making flange connections. Particular attention should be paid to ensure:
- Concentric alignment of the disk and gaskets
- Uniform cross-tightening of flange bolts
- Adequate support of piping to withstand external loading and thrust during blowdown.
- Protection of personnel and equipment against high velocity open discharge of process material and rupture disk particles.
METAL Rupture Disk Installation
Graphite Rupture Disk Replacement
When replacing a metal rupture disk with a ZOOK Graphite Rupture Disk, a graphite lined armored spacer ring can be provided to fill the space of existing flange face-to-face distance, eliminating the need for piping modifications. Detailed installation instructions are provided with each disk.
