Zook Mono Bursting Disc

The Zook Mono Bursting Disc is the best choice for low and intermediate burst ratings.The Zook Mono Bursting Disc is a Graphite Bursting Disc that protects equipment and personnel from the effects of overpressurisation in static and dynamic pressurised systems. The discs are designed to rupture at a predetermined burst rating when installed in a piping system.

Impervious Graphite – Each disc is made from a single piece of graphite, a high-purity form of carbon, which is impregnated with phenolic resin. The resulting material, called impervious graphite, is impermeable and resistant to most corrosives.

Options – Easy to install and maintain, graphite bursting discs are tamper proof, have no moving parts and mount directly between standard flanges without special holders.

• Mounts directly between standard ASME B16.5 flanges
• Process pressure is applied to the counterbore side of the rupture disc
• Operate up to 90% of marked burst pressure
• Vacuum supports are available for ratings below 25 psig
• Stocked ratings are available for immediate shipment
• Designed to fit ASME B16.5 Class 150 flanges (Higher ratings to fit Class 300 flanges are furnished in the INVERTED and DUPLEX Type Discs)
• Burst ratings 0.25 to 150 psig
•  0% manufacturing range
• Operating pressures to 90% of the disc’s marked burst pressure (Contact your Zook supplier for operating ratio for burst pressures below 40 psig)
• Temperature ratings –290°F to +700°F (–179°C to +371°C). Maximum temperature rating without insulation is 430°F (221°C) or 700°F (371°C) with insulation. Contact ZOOK for higher temperature ratings. The specified temperature shall be at the disc location at the time when the disc is expected to rupture.
• Counterbored side of the disc contacts the process media
• Vacuum supports are available for ratings below 25 psig
• May be configured to withstand high back pressure generated in closed piping systems – request Bak-Pressure™ bulletin
• Sizes: 1″, 1-1/2″, 2″, 3″, 4″, 6″, 8″ to fit – ASME B16.5 Class 150 flanges – Burst Ratings: 10, 15, 20, 25, 30, 40, 50, 75, 100,125, 150 psig @ 22°C  (72°F)
  Note: Sizes 3″ through 8″ with burst ratings 125 and 150 psig @ 22°C  (72°F) are stocked in INVERTED type
• ASME UD, PED/CE and TUV markings available
• Various vacuum support types available
• Counterbored side of the disc contacts the process media
