STAR X™ Rupture Disc

This reverse-acting rupture disc is ideal for primary and secondary system relief protection or, when used to isolate a safety relief valve, provides an effective means of fugitive emission control. Additional system-protection applications include installation in transfer piping, chemical reactors, pressure vessels, storage vessels and heat exchangers.

The STAR X incorporates a handling ring to reduce torque sensitivity. As with all our other reverse-acting rupture discs, every STAR X rupture disc is proof pressure-tested to 90% prior to shipment. The STAR X is compatible with the BDI alarm system.

The STAR X rupture disk features:

• A safety ratio of 1.5 or less - designed so a damaged rupture disc will provide pressure relief at or less than 1.5 times the rated burst pressure of the rupture disc
• Operational capacity in pressure-to-full-vacuum cycling without additional vacuum support
• A standard zero manufacturing range and an optional -5% or -10% manufacturing range
• A permanent flow-direction tag for visual verification of proper orientation
• Our precision failure-initiating indent, to:
  • Weaken thicker materials to achieve low reversal pressures: the use of thicker materials also provides sturdier and more corrosion-resistant discs
  • Ensure thicker material properly collapses and fully opens along the score line
  • Help ensure the rupture disc dome will not fragment

• Nominal Size Range1″ - 6″ (25 mm - 150 mm)
• Burst Pressure Range: 13 psig - 140 psig (0.896 barg - 9.65 barg)
• Maximum Recommended Operating Ratio90% of the rupture disc's rated (stamped) burst pressure
• Seating Configuration: Flat seat
• Service: Liquid or Gas
• BDI Alarm System Compatible?: Yes
• ASME Code Symbol Stamp Available?: Yes

Chemical Processing
Our rupture disks are manufactured with chemical processing in mind - corrosion resistance, leak tightness, high accuracy and durability come standard.

Food & Beverage Processing
We understand that product purity and safety are critical in food-related industries, so we provide hygienic and aseptic vessels and piping to assure compliance with FDA and 3A requirements.

Oil & Gas (Petrochemical)
The hydrocarbon industries require cost-effective system protection with a special focus on reducing fugitive emissions. Our catalog of configurations, materials, burst ratings and sizes make our rupture discs the right choice for these operations.

Pharmaceutical & Biotechnology
We focus on solutions to meet the stringent requirements of pharmaceutical processing - wherever perfectly hygienic facilities and hermetically sealed antiseptic systems are a must.
