KSRRK Rupture Disc & Explosion Panel
KSRRK Rupture Disc & Explosion Panel Overview
ZIRCO is proud to distribute KSPC KSRRK Rupture Discs & Explosion Panels as the official representative for Western Canada. These fail-safe pressure relief devices provide critical protection for storage tanks and process equipment when primary safety devices are compromised or during extreme pressure rise scenarios. Designed as single-use emergency relief devices that rupture at preset pressures to prevent catastrophic equipment failure and ensure personnel safety.
The KSRRK series is specifically engineered for emergency pressure relief applications including fire exposure, process upsets, and abrupt pressure rise events. When normal pressure relief devices are insufficient or damaged, the rupture disc provides reliable fail-safe protection by bursting at a precisely calculated pressure, allowing rapid pressure evacuation and protecting the structural integrity of storage tanks, reactors, and process vessels throughout Western Canada's industrial facilities.
Constructed from premium materials including stainless steel, Hastelloy, Inconel, and special alloys, these devices handle corrosive oils, harsh chemical environments, and materials prone to synthetic reactions. Suitable for extreme temperature environments from cryogenic applications to high-heat processes. The rupture disc design prevents oil leakage and environmental contamination while providing dependable emergency protection for oil sands storage tanks, petrochemical reactors, gas processing plants, mining operations, and chemical storage facilities across Alberta, British Columbia, and Saskatchewan.

Installation Requirements
The KSRRK rupture disc must be installed in accordance with ASME Section VIII, API 2000, and local applicable codes. Key installation considerations:
- Install upstream or downstream of primary relief valve as backup protection
- Ensure proper orientation as specified for the rupture disc type (forward-acting, reverse-acting, or composite)
- Verify holder/housing compatibility with process connections (flanges, threaded, sanitary fittings)
- Select appropriate material for compatibility with stored product and environmental conditions
- Coordinate burst pressure rating with vessel MAWP (Maximum Allowable Working Pressure)
- Provide adequate discharge piping to direct relieved media to safe location
- Replace immediately after activation (single-use device, no reclosing capability)
- Regular inspection recommended to verify integrity and replace if damage or corrosion is detected
What Is a Rupture Disc?
A rupture disc (also known as a burst disc or safety disc) is a thin, specially designed membrane made of metal or graphite that is precision-engineered to rupture at a specific pressure. This fail-safe safety device provides instant pressure relief when the internal pressure exceeds the disc's rated burst pressure, protecting equipment from catastrophic failure and preventing dangerous explosions. Unlike spring-loaded relief valves, rupture discs have no moving parts and provide instantaneous response time.
Rupture discs serve as primary relief devices in many applications and as secondary backup protection when installed in series with conventional pressure relief valves. In the backup role, they provide critical protection if the primary valve fails, becomes blocked, or is overwhelmed during emergency conditions such as fire exposure. The single-use design means the disc must be replaced after activation, but this ensures complete system integrity reset with each new installation.
Rupture Disc vs. Explosion Panel: While both function on the same principle, rupture discs are typically smaller circular devices for liquid or gas service in pressure vessels and piping. Explosion panels are larger rectangular panels designed for rapid pressure relief during deflagration or explosion events in dust collectors, process vessels, and buildings. Both provide fail-safe emergency protection but are optimized for different applications.
Rupture Disc vs. Relief Valve: Relief valves are reclosing spring-loaded devices that open proportionally to overpressure and close when normal pressure is restored. Rupture discs are single-use devices that provide instantaneous, non-reclosing relief at a precise pressure. Rupture discs are often specified as backup to relief valves, for corrosive service that would damage valve internals, or when zero leakage and instant response are critical requirements.
Rupture Disc vs. Relief Valve Comparison
| Characteristic | Rupture Disc | Relief Valve |
|---|---|---|
| Operation | Single-use, ruptures at set pressure | Reclosing, reusable |
| Response Time | Instantaneous | Delayed (spring response) |
| Leakage | Zero leakage until burst | May have minor leakage |
| Maintenance | None required until activation | Regular testing and maintenance |
| Cost | Lower initial cost | Higher initial cost |
| Replacement | Required after each activation | Can be reset after activation |
| Best Application | Fail-safe backup, corrosive service, emergency relief | Primary pressure relief, reclosing required |
