Abstract
There is provided a breech lock coupling for coupling riser sections together. The breech lock coupling may be used non-pre-loaded or pre-loaded according to the user's preferences. In addition, the breech lock coupling may be disassembled for inspection and maintenance and reassembled. A locking ring secures two coupling components together. The coupling components may be attached to opposite ends of the riser sections, such as via welding. The locking ring may be pre-attached to the first coupling component for easy storage and fast assembly. Assembly of the riser may be accomplished by inserting the second coupling component into the locking ring and the first coupling component, then rotating the locking ring with respect to the second component. Furthermore, the coupling may be pre-loaded by tightening fasteners on the locking ring to provide a more stable coupling. Unlike with traditional riser couplings, the pre-load fasteners may be tightened via hand-held tools.
