Bursting Disc Safety Device

The bursting disc safety device is an emergency depressurization device which is actuated by pressure difference and non-automatic shut down. It is also a safety relief device which is applicable in pressure vessels, pipes or other sealed space to avoid overpressure or excessive vacuum. The bursting disc safety device has many advantages compared to the safety valve, such as large relief area, sensitive action, high accuracy, good sealing quality, corrosion resistance and no blockage. The bursting disc can either be used individually or combined with the safety valve.
The bursting disc safety device is a safety device for non-reclosing pressure relief, composed of bursting discs (or bursting disc assembly), holders (or support rings, pressure rings) and other fittings. When the differential pressure of the two sides of bursting disc reaches the desired value under target temperature, the bursting disc would act immediately (crack or peel) to release pressure medium. The holders are used to clamp and protect the bursting discs to ensure the stable bursting pressure.

The basic structure types of bursting disc safety device produced by our company are: flat bursting disc, conventional domed disc, reverse domed bursting disc and graphite bursting disc.
The following standards are applicable for the bursting disc safety device produced by our company:
·GB567－1999 “Bursting disc and bursting disc device”
·GB150－1998 “Steel pressure vessels”
·State Bureau of Quality and Technical Supervision “Supervision regulation on safety technology for pressure vessel”
