Extruder Rupture Disk – Temperature Derating

  • Temp_Correction_for_Rupture_Discs.jpg

MPI’s extruder rupture disks incorporate a standard Inconel burst disk. The Inconel disk allows the bursts plugs to be used over a wide temperature range with minimal burst pressure changes (a change of approximately 2% over the 300°F-600°F range). The chart below will help users estimate changes in rating based on temperature. 

Temperature Derating of MPI Extruder Rupture Disks (Inconel)

Note: The above chart is only valid for Inconel disk material. Other materials will have different derating curves.

Full engineering support is available via email and phone.

MPI also carries a complete line of melt pressure products, including melt pressure transducers, melt pressure transmitters, melt pressure indicators, melt pressure cables, connectors, hole plugs, hole drill kits, and hole clean kits.
