A burst disk is a widely used pressure relief device. When the internal pressure of a system exceeds the preset value, the burst disk ruptures instantly to release pressure rapidly, thereby protecting equipment from overpressure explosions or damage. It can break quickly once the critical pressure is reached, enabling fast response. High pressure burst disks are especially suitable for working conditions where vacuum or negative pressure may occur; they can withstand bidirectional pressure differences and ensure reliable system sealing.
The metallurgical industry involves harsh environments with high temperature, high pressure, dust and corrosive media—such as blast furnaces, converters, continuous casters and coking systems in steel production. These facilities are often exposed to the risk of sudden overpressure. Improper pressure control may lead to equipment rupture, medium leakage and even major safety accidents. In the power generation industry, particularly in thermal power plant components like boilers, steam turbines, steam pipelines, as well as nuclear power and geothermal systems, there is also a hidden danger of overpressure from high-pressure steam or gas. Violent pressure fluctuations and subsequent overpressure can cause boiler explosions or system shutdowns, resulting in huge economic losses and safety risks.
Burst disks deliver reliable overpressure protection in these industries. Our products can be customized according to medium properties, temperature ranges and pressure ratings, featuring minimal burst pressure deviation. Each burst disk undergoes factory pressure and sealing tests to guarantee product reliability.
Application Advantages:
Adaptable to Diverse Working Conditions:
Burst disks can be made of various customized materials, such as high-temperature and corrosion-resistant alloys, allowing them to withstand harsh conditions of high temperature, high pressure and dust. They are ideal for the high-temperature and corrosive environments of metallurgical blast furnaces as well as the extreme temperature and pressure conditions of power generation boilers. Every high pressure burst disk is verified through fatigue life testing, capable of withstanding multiple pressure cycles to ensure long-term stable operation.
Cost-Effective and Easy to Maintain:
Burst disks are relatively low-priced and simple to install, requiring no frequent maintenance—just a one-time replacement after use. They provide reliable protection for high-pressure systems at a low cost, helping enterprises cut overall safety protection expenses and reduce downtime losses.
Flexible Combination with Safety Valves:
A high pressure burst disk can serve as either a primary protection device or an auxiliary component paired with safety valves. It enhances system redundancy and improves the overall safety level in the demanding environments of metallurgy and power generation sectors.
