Rupture Disc For Compressor
Product Model: ZD-FL08 (Indicator Flat Disc)
Design: Standard flat or pre-scored rupture disc assembly with a built-in mechanical burst detection device.
Indicator Type: Spring-loaded pin that protrudes visibly upon disc rupture, or a magnetic flag that changes position.
Key Feature: Provides immediate, local visual confirmation that the rupture disc has activated, without needing electrical connections.
Pressure Range: Adaptable to the disc's range, typically 0.5 barg to 25 barg.
Primary Use: Equipment in remote locations, on skids, or in facilities where quick visual inspection is required to determine system status after an alarm or shutdown.
Overview
Knowing whether a rupture disc has activated is crucial for safety investigations, maintenance planning, and system restart procedures. This flat rupture disc incorporates a simple, reliable mechanical indicator directly into its housing. When the disc bursts, the sudden pressure change or movement within the holder triggers a brightly colored pin to pop out or a flag to flip. This offers an unambiguous, at-a-glance status check, ensuring personnel can quickly and safely assess the situation. It eliminates guesswork and the potential hazards associated with manually checking a potentially pressurized system.
Features & Benefits
Instant Visual Confirmation: Allows operators to identify a tripped disc from a safe distance, speeding up response and lockout/tagout procedures.
Intrinsically Safe: A purely mechanical device, it requires no power supply and is safe for use in all hazardous areas.
Low Maintenance & Reliable: No batteries or electronics to fail. The mechanism is simple and robust.
Cost-Effective Monitoring: Provides a basic level of status monitoring without the cost of electronic sensors and wiring.
How It Works
The indicator mechanism is mechanically linked to the pressure conditions inside the holder. In one common design, the bursting of the disc releases pressure from a small chamber, allowing a spring to push a colored indicator pin outward. In another, the force of the disc petal movement or pressure wave triggers a lever that releases a magnetic flag.
Specifications (Descriptive)
Available for common flat disc sizes, e.g., DN50 to DN150. The indicator type (pin or flag) and color (typically red or yellow) can be specified. The indicator is reset manually after disc replacement by pushing the pin back in or resetting the flag. The assembly is sealed to prevent process leakage through the indicator. It does not affect the burst pressure or performance of the disc itself.
Q&A
Q: Can the indicator be connected to a remote alarm?
A: This is a local visual indicator only. For remote alarm capability, you would need to select a disc assembly with an electric burst sensor (micro-switch) that can be wired to your control system.
Q: What if the indicator gets stuck or fails to trigger?
A: While highly reliable, mechanical devices can theoretically fail. It should be included in routine visual inspection rounds. The primary safety function—the disc bursting—is completely independent of the indicator.
Q: Is the indicator visible from all directions?
A: Typically, the protruding pin or flag is designed to be highly visible from the front/side of the assembly. The installation orientation should be considered to ensure the indicator faces an accessible viewing point.
