Thread Hold Rupture discs are designed for Forward acting and Reverse Buckling. Forward acting Thread Hold Rupture Discs are of three types

Posted on: July-22-2024

1) Composite Disc ( Multi Layered )
• Composite Disc is designed for Low pressure application. Ensure resistance to Vacuum and Back pressure by a support
2) Simple Forward acting Disc
• Simple forward acting discs are designed for high pressure application.
3) Scored Forward acting Disc
• Scored Forward acting disc is non fragmenting and designed to meet the customer requirement without affecting the flow rate. The disc seating are designed for standard 30deg angle seating and Flat seating based on the application.

Reverse Acting Thread Hold Rupture Disc are Two types

1) Angular Scored Reverse acting Rupture disc

Angular Scored Reverse acting Discs are designed to Rupture where the operating pressure is 90% of the Burst Pressure. The score is designed for non fragmentation.

2) Simple scored doomed Reverse acting Rupture Disc

A cutting edge is provided for the scored Simple doom Disc to ensure 100% opening and flow. The Reverse buckling disc are Flat seated by its construction. For all the above Rupture Discs are Hold by Threaded Union, Welding in Plugs and Crimping to meet the customer Safety and cost.

A rupture disk with a Thread hold is a type of pressure relief device used in industrial processes to prevent overpressure in equipment or systems. Here are some applications:

1. Chemical Processing: Protects vessels, reactors, and piping from excessive pressure buildup.
2. Oil and Gas: Used in wellheads, separators, and pipelines to prevent overpressure and damage.
3. Aerospace: Used in fuel systems, hydraulic systems, and engine compartments.
4. Compressed Gas Systems: Protects compressors, tanks, and pipelines from excessive pressure buildup.

Applications also include:

• - Cryogenic systems
• - High-pressure testing
• - Safety instrumentation
• - Process vessels
• - Pipeline protection

The threaded holder allows for easy installation and replacement of the rupture disk, making it a convenient and reliable option for various industries.

Pressure relief: Rupture discs burst at a predetermined pressure, releasing excess pressure and preventing damage to equipment and systems.

Threaded holder: The holder provides a secure and convenient way to install and replace the rupture disk, often with a threaded connection (e.g., NPT or BSP).

Materials: Rupture disks and holders are typically made from corrosion-resistant materials like stainless steel, nickel alloys, or titanium to withstand harsh environments.

Sizes: Various sizes and thread configurations are available to fit different applications and equipment.

Customization: Rupture disks can be designed for specific pressure ratings, temperatures, and process conditions.

Burst tolerance: The acceptable pressure range for disk failure, ensuring reliable performance.

Operating ratio: The ratio of operating pressure to burst pressure, typically 80% or more.

Threaded holder designs:

• - NPT (National Pipe Taper) threads
• - BSP (British Standard Pipe) threads
• - UNF (Unified National Fine) threads
• - Metric threads

Materials for high-temperature and high-pressure applications:

• - Inconel
• - Monel
• - Hastelloy
• - Titanium
