Insert Assembly
Shown with optional tell tale assembly
The Insert Rupture Disk Holder is the most popular of all Rupture Disk Holders. The Oseco Insert holder is a reduced diameter flat-faced flange assembly that bolts between standard ANSI pipe flanges and fits with the bolt circle. This holder allows the rupture disk to be pre-assembled to insure it is properly seated before installation into the pressure system. Insert Rupture Disk Holders are available in nominal standard ANSI flange ratings up to 24". Standard materials of construction are carbon steel and 316 Stainless Steel. Other materials are available upon request.
Oseco Insert Holders are offered in three seating arrangements. The type of rupture disk to be used determines which seating arrangement to specify.
Union Assembly
The Oseco Union Rupture Disk Holders are low in cost and are ideal for applications where installation space is limited. Time to replace the rupture disk is reduced as only the union nut is removed to obtain access to the rupture disk. Standard sizes are 1/2", 1", 1 1/2" and 2" nominal pipe sizes. Threaded inlet and outlet connections are standard. Consult factory for the availability of welded connections . The Union Rupture Disk Holder has the standard 30° angular seat arrangement and is for use with the STD/STDV series and CO/COV series rupture disks. Standard Materials are carbon steel and 316 Stainless Steel. Special materials are available on request.
Threaded Assembly
The Oseco Threaded Rupture Disk Holder is widely used on high pressure applications up to 15,000 psig. The standard unit utilizes a 11/16" flat seat or 1/2" flat seat hold-down ring. For disk rating of 1000 psig and less, the 11/16" hold-down ring is used. Standard material of construction is 316 Stainless Steel. Standard inlet connections are 1/4" MPT or 1/2" MPT with 1/2" MPT or muffled outlet. Other materials and connections are available to your exact specifications.
