System Safety - UHV Burst Disks

ANCORPs UHV burst disk is designed for our customers who require protection from accidental over-pressurization of their vacuum systems. The ASME UD certified overpressure burst disk, high-pressure burst disk, and low-pressure burst disk feature all-metal stainless steel construction designed for ultra-high vacuum (UHV) applications.

 

Application

Vacuum systems are normally rated for an external load of one atmosphere and should not be exposed to excess positive pressure. For this reason, ANCORP has designed a line of burst disks that help to prevent the accidental pressurization of a vacuum system. ANCORP burst disks are connected using ConFlat (CF) metal seal flanges. Sizes include CF133 or CF275 flanges. Gas recovery port connections are available in CF338 or QF50 flanges.

 

Design

The burst disk membrane is scored to prevent fragmenting upon rupture, thus protecting personnel and equipment from harm. However, once the disk has ruptured it is no longer usable and must be replaced.
