Bursting Disc Device
A bursting disc device is a non-reclosing pressure relief component. It operates when static pressure at the inlet reaches a specified level, causing the pressure-bearing diaphragm to rupture and release the excess pressure. In simple terms, it is a single-use safety device: under the designated burst temperature, once the pressure differential across the disc reaches the preset value, the disc will rupture or detach to discharge the medium.
The design and production of bursting discs must meet the requirements of applicable safety technical standards. Each product must be delivered with a quality certificate and equipped with a secure metal nameplate.
FAQ
Q1: What is your company’s main business, and do you have the necessary certifications?
A1: We focus on industrial explosion protection and pressure relief safety technologies. Our main products include bursting discs, flame arresters, explosion isolation valves, and flameless venting systems.
We hold the Special Equipment Manufacturing License (for bursting disc devices) issued by the State Administration for Market Regulation (SAMR). All products comply with national standards such as GB/T 567 and TSG ZF003, and we can also provide international certifications including ATEX and PED upon request.
Q2: How should I choose the correct device for my application?
A2: Proper selection requires the following essential parameters:
Medium: Type and composition (e.g., gases, liquids, or dust such as hydrogen, methane, or corn starch dust).
Operating Pressure & Temperature: Normal working conditions.
Burst/Design Pressure & Temperature: Activation pressure and the temperature of the medium at that moment.
Relief Capacity / Line Size: Required discharge capability or pipeline nominal diameter (DN).
Installation Environment: Indoor or outdoor, mounted on equipment or at a pipeline end.
Additional Requirements: Corrosion resistance, vacuum support, leakage detection, etc.
