Reverse Buckling Rupture Discs are commonly used safety devices in industrial fields such as chemical, petroleum and natural gas, energy, power, metallurgy, and pharmaceuticals, as well as in pressure vessels and pipeline systems. They are one-time overpressure protection components installed on pressure equipment or pipelines. When the system pressure or temperature rises abnormally and exceeds the set value, the Reverse Buckling Rupture Disc will rupture rapidly under predetermined conditions to release pressure, preventing equipment damage or even explosions, and ensuring the safety of both the equipment and personnel.
How to Determine Whether a Reverse Buckling Rupture Disc Needs Immediate Replacement:
1.The Reverse Buckling Rupture Disc has already ruptured:
Once the disc has actuated and released pressure, even if it is only partially ruptured or has minor cracks, it must be replaced immediately and cannot continue to be used. The disc is designed as a one-time safety protection device; after use, it loses its sealing capability and can no longer isolate the medium inside the equipment. Continuing to use it may lead to continuous leakage of the medium, environmental pollution, material waste, or safety hazards.
2.Obvious corrosion or surface damage:
The burst pressure of a Reverse Buckling Rupture Disc is precisely calculated and manufactured based on material properties, thickness control, and structural stress. If corrosion, pitting, scratches, deformation, or thinning of the material appears on the disc surface, its structure and stress distribution are altered. This can cause deviations in burst pressure, potentially leading to premature rupture or failure to rupture at the set pressure. In such cases, the disc must be replaced promptly.
3.Changes in system operating conditions:
The selection of a Reverse Buckling Rupture Disc is based on specific operating conditions. Its material, thickness, structural form, and set burst pressure are all chosen according to the medium properties and operating parameters at that time. If the system’s medium, operating pressure, temperature range, or operating mode changes, the original disc may no longer be suitable. For example, an increase in operating temperature directly affects the disc material strength, causing a shift in burst pressure, which may result in premature rupture, delayed rupture, or failure to rupture under overpressure, compromising equipment safety.
4.Exceeding the recommended service or inspection cycle:
Reverse Buckling Rupture Discs usually have recommended service or inspection intervals to prevent potential failure. Continuing to use a disc beyond its recommended period may lead to premature rupture or failure to rupture under overpressure, creating safety risks. Replacing the disc promptly according to regulations helps ensure the safe operation of the pressure system.
