Safety pressure relief devices are the most critical safety components in pressure vessels and pressure pipelines. These devices can be classified based on their structure into safety valves, rupture discs, explosion-proof caps, fusible plugs, and combination forms made up of safety valves and rupture discs. The most commonly used types are safety valves, rupture discs, and combination forms.
Characteristics of Safety Valves and High Pressure Burst Disks:
The characteristic of a safety valve is that its opening pressure can be adjusted, allowing pressure relief without interrupting production. However, safety valves generally have poor sealing performance, and during operation, a small amount of material may leak. They are not suitable for rapid pressure relief situations.
The characteristic of a High Pressure Burst Disk is that once it has completed its pressure relief function, it cannot return to its original state, causing an operational interruption. However, rupture discs have excellent sealing properties, fast response times, high sensitivity, and large discharge capacity. They are well-suited for media with high viscosity, toxicity, and corrosiveness, particularly in situations where pressure rapidly rises due to abnormal chemical reactions or when there is a risk of explosion.
Combination Application of Safety Valves and Rupture Discs:
1.Installing Safety Valves and Rupture Discs Separately on the Pressure Vessel:
In this configuration, the safety valve serves as the primary relief device, discharging when overpressure occurs due to physical causes. The rupture disc acts as a secondary relief device, discharging when abnormal operating conditions cause rapid pressure rise or when a fire occurs, requiring a large discharge area. Our High Pressure Burst Disks have a simple structure, are easy to install and adjust, and respond faster than conventional high-pressure valves. They can release pressure within milliseconds, avoiding potential equipment damage and personnel injury caused by rapid pressure increases.
2.Installing the Rupture Disc at the Outlet of the Safety Valve:
This configuration is suitable for pressure vessels where pressure fluctuates or where the discharge pipeline may contain corrosive gases. The safety valve provides stabilization to the rupture disc, while the High Pressure Burst Disk prevents leakage from the safety valve and protects the safety valve from corrosion caused by corrosive gases in the discharge pipeline.
3.Installing the Rupture Disc at the Inlet of the Safety Valve:
This application is ideal for situations where high sealing and corrosion resistance are required. The rupture disc protects the safety valve, and the safety valve allows the vessel to continue operation. In this case, the calibrated burst pressure of the High Pressure Burst Disk should match the set pressure of the safety valve.
