Fike’s Hammer Union rupture disc holder, or Wing Nut Union, is designed for installation locations that are hard to reach, such as in oil field applications. The unique, proven design of the Hammer Union allows for quick, easy installation and dismantling of units. Built to withstand the force of a hammer for optimal field use, the Hammer Union is great in surface production and drilling operation applications.
Designed to accept a Fike CPD rupture disc, the Hammer Union rupture disc holder features a 30° angular seating surface that provides the compression necessary to clamp the rupture disc securely into place. The Fike Hammer Union will also accept most discs using the industry standard 30° seat.
Hammer Union Overview
Union Type Rupture Disc Holder
Fike’s Union Type rupture disc holder is a three-piece unit consisting of a base flange (inlet), a holddown flange (outlet) and a union nut. The 30° angular seating surfaces of these holders are machined to grip Conventional Pre-bulged P/CPV Series and HO/HOV Series Rupture Discs. The base and holddown flanges grip the rupture disc while the union nut provides the compression necessary to create a metal-to-metal seal.
Fike’s Union Type rupture disc holders can be incorporated into a pressure system by welded or threaded connections, or any combination of the two.
