SAFETY SYSTEMS SIGMA EXLM Reverse Buckling Rupture Disk Designed for the Highest Operating Pressure in Gas or Liquid Service

SigmaTM, Sigma EXLTM Rupture Disks for the Highest Operating Pressure in Gas or Liquid Service The Sigma EXL reverse buckling rupture disk has been developed to provide the highest operating pressure capability available from a rupture disk pressure relief device. Sigma EXL technology coupled with either the SRI-7RS, SRB-7RS or SRB-7FS safety heads combine the accuracy and reliability of reverse buckling disk technology with unique disk and safety head design features that enable the Sigma EXL disk to operate to 95% of the marked burst pressure (100% of minimum burst pressure according to CEN...

BURST TEST The certification procedure for Sigma EXL™ and Sigma™ rupture disks exceeds those required by standard industry codes and standards that require limited destructive testing to validate burst pressure and permit acceptance of the lot with any burst test distribution and uncentered test data. The Sigma EXL and Sigma disks' test data is graphically presented on their burst test certificate (see example). The curve includes 'in process' and final certification burst test data to build a clear picture of the burst pressure distribution. Only when the data is appropriately centered and distributed...
