Influence of improper mating of inlet and outlet flanges of bursting disc device on properties of bursting disc

Sep 28, 2018

The bursting disc must be installed in the clamping device or flange supporting it, and the flange diameter on the discharge side of the bursting disc device must be larger than the nominal diameter of the bursting disc, otherwise it will have a negative impact on the discharge of the bursting disc, preventing the bursting disc from opening the discharge channel and failing to meet the discharge requirements of the bursting disc.

Example: as shown in FIG. 11, if the inner diameter of the pressure relief side flange is smaller than the discharge diameter of the bursting disc, the bursting disc will be blocked by the pressure relief side flange in the process of overturning the bursting pressure, which will affect the cracking state of the bursting disc.
