As a key component of pressure safety devices, the replacement cycle of graphite bursting disc has a direct impact on the safety and efficiency of equipment operation. Reasonable maintenance can not only avoid unexpected downtime, but also reduce long-term costs. So, how often should graphite bursting discs be replaced? What factors affect its lifespan? How to choose the right bursting disc to extend its service life?
1. Conventional replacement cycle of graphite bursting discs.
In general, the recommended replacement cycle of graphite bursting discs is 2 to 3 years. However, the specific time needs to be adjusted according to the working conditions:
(1) Standard working conditions (stable pressure, no strong corrosive media): can be appropriately extended to 3 years.
(2) Severe working conditions (high temperature, strong corrosion, frequent pressure fluctuations): it is recommended to shorten to 1 year or shorter, and strengthen regular inspections.
2. Key factors affecting the replacement cycle.
(1) Corrosiveness of the medium.
Graphite itself is corrosion-resistant, but some strong acids, strong alkalis or oxidizing media may accelerate material aging, and the replacement cycle needs to be shortened.
(2) Temperature and pressure fluctuations.
Long-term high temperature or frequent pressure changes will cause material fatigue and affect blasting accuracy, and need to be replaced in advance.
(3) Mechanical damage.
If cracks, scratches or deformation are found during installation or maintenance, they must be replaced immediately to avoid the risk of failure.
(4) Historical usage data.
If the same type of rupture disc has ruptured prematurely under the same working conditions, the replacement plan should be optimized.
3. These conditions require immediate replacement.
The graphite bursting disc exceeds the calibrated pressure but is not broken.
The equipment is restarted after long-term disuse (more than 6 months).
There are obvious signs of damage, corrosion or leakage on the surface.
4. Choose a more durable graphite bursting disc to reduce the frequency of replacement.
To reduce maintenance costs and improve safety, you must choose a high-performance graphite bursting disc. Our company was founded in 1959 and is the first professional manufacturer of bursting disc safety devices after the founding of New China that integrates design, manufacturing, sales and service. Our graphite bursting discs are made of high-purity graphite materials, and their corrosion resistance and compressive fatigue resistance are significantly better than ordinary products. They are especially suitable for chemical, pharmaceutical, energy and other environments.
Optimize the selection of bursting discs to make safety more lasting and maintenance more efficient! Welcome to contact us.
