Panel bursting disc / 316 stainless steel rupture disk / disc rupture/ concave bursting discs
The bursting disc safety device is a pressure relief device which is controlled by the pressure difference and has an effect on the pressure relief and pressure relief device with no more closed.Its role is to prevent the pressure equipment in the operation process of the sudden change in pressure, to reach the pressure equipment can not bear, the bursting of the safety device, with the release of pressure, pressure equipment within the pressure to reduce, safe access to security.
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 so on.
PF bursting disc
Structure features:
composite bursting disc, composed of a strength film, a sealing film and other components. For the situations where the back pressure needs to be withstood, a support shall be added. Holes and slots (radial or circumferential) are made in the strength film and back support film to weaken the material strength. The tensile failure occurs in the cross-section with minimum pitch when over pressure.
