OTHER - Overpressure relief devices/rupture disks

BS&B Safety Systems, LLC

BS&B Safety Systems’ Reverse Buckling disk provides a pressure relief solution for burst pres-
sures ranging from a few inches of water column / a few millibar to over 70,000 psig / 488 bar.

They offer extensive application expertise and a variety of designs for geothermal applications
including rupture disks for safety relief valve isolation or stand-alone protection of: steam and
brine piping, binary luid systems, separators, and lash vessels.

effective in removing pre-existing hard elemental sulfur deposits, and in preventing the formation of
new elemental sulfur deposits.

In a system in which elemental sulfur deposits have formed, DTEA II* attacks the deposits, causing
disaggregation and release of the deposits from system surfaces. Shown below are:
