BURST DISK OPTIONAL WITH GAS RECOVERY PORT

Product Description

We are proud to announce our new UHV burst disk designed for our
customers who require protection from accidental over-pressurization of their
vacuum systems. The ASME UD certified overpressure burst disk and low
pressure burst disk both feature all-metal stainless steel construction designed
for UHV applications.
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 offers burst disks in CF16 or CF40 metal seal
flange connections. Gas recovery port connections are available in CF338 or
KF50 flanges.
ANCORP has designed the ASME burst disk to be ASME UD certified and
10CFR851 compliant. Our low pressure burst disk is designed to be ISO 4126-2
compliant. Burst disks are constructed with a frustum metal membrane which
is capable of sustaining a vacuum load. The low pressure burst disk will activate
if the pressure inside a vacuum system increases to 5 PSIG, while the ASME
overpressure burst disk will activate if the pressure reaches 11.5 PSIG. 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.
ASME Overpressure Burst Disk (9-11.5 PSIG)
Our ASME overpressure burst disks are designed for systems that require pressure
relief above atmospheric pressure. The disk membrane will activate and fully open
when a pressure differential between 9 and 11.5 PSIG is reached. The optional gas
recovery port can be connected to your gas line using a CF338 or KF50 flange.
Low Pressure Burst Disk (5-7 PSIG)
Our low pressure burst disks are designed with a frustum metal membrane
which is able to sustain a vacuum load and are ISO 4126-2 compliant. The disk
membrane will activate and fully open when a pressure differential between
5 and 7 PSIG is reached. In scenarios where gas back-fill could be dangerous,
the optional gas recovery port can be connected to your gas line using a
CF338 or KF50 flange.
