DonadonSDD disc holders are specifically designed to ensure maximum reliability, optimize flow (due to optimal opening of rupture discs), assure proper orientation in piping system, provide a tight seal, and prevent fragmentation of DonadonSDD rupture disc.
Typically, a bursting disc holder is a two-piece unit consisting of a base flange (inlet) and a holddown flange (outlet). The face of the holder is machined to hold the bursting disc and forms a leak-tight metal-to-metal seal.
This prevents the rupture disc from being damaged and allows unlimited inspection scenarios (temporary removal of the rupture disc for visual inspection)
Keyfeatures & technical benefits
- HIF and HRF flanged disc holders, previously coded as AZ-60, are designed to be directly fitted on the piping.
- Composed of two flanged parts, complete with steel bolts, these holders provide secure and reliable mounting for rupture discs.
- HIF and HRF models are fully customizable and can be supplied with different types of couplings that can be fitted with one another, including female or male threaded NPT, GAS, or in accordance with other international standards, butt welding, and socket welding.
- The flow arrows on the holder and rupture disc tags confirm proper flow direction.
- Gauge tap connection (1/4” or ½”) NPT are available on request.
