UNISERT® ASSEMBLY

UNISERT ASSEMBLY What is the UNISERT Assembly? The UNISERT Assembly is a flat seat rupture disc holder which provides improved rupture disc sealing capabilities. It is designed to house either the MICRO X® Rupture Disc or the Composite Flat Seat Rupture Disc. These non-fragmenting designed rupture discs provide a wide choice of burst ratings from the low pressures of the Composite (FS) Rupture Disc through the higher pressures of the scored positive acting MICRO X Rupture Disc. flow orientation between the companion flanges. Both the J-Hook and alignment pins are provided on all 1" through...

SPECIFICATIONS Manufacturing Range Burst Tolerance Manufacturing range is defined as the allowable pressure range within which a rupture disc is rated. It is based upon the customer specified burst pressure. The standard manufacturing ranges for Continental’s MICRO X Rupture Disc include -5 psig for burst pressure ratings below 50 psig and -10% for burst pressures 50 psig and above. Manufacturing ranges of -2 psig for burst pressure ratings below 50 psig and -5% for burst pressures 50 psig and above are also available. The manufacturing ranges for Continental’s Composite (FS) Rupture Discs...
