Inner bore coupling assembly
Patent published on the 2025-03-06 in WO under Ref WO2025049280 by BAKER HUGHES OILFIELD OPERATIONS LLC [US] (Deiters Arne [us], Huber Cord [us])
Abstract: A mounting system secures a component in a tubular, which includes a compression element and an annular flow guide. The flow guide is attached to the component by a threaded connection. The compression collar and flow guide have complementary profiles on their respective inner and outer surfaces, which when the compression collar is coaxially urged along the outer surface of the flow guide, the compression collar is radially expanded into compressive engagement with an inner surface of the tubul[...]
Our summary: Inner bore coupling assembly with compression collar, annular flow guide, and thrust ring for securing a component in a tubular with a threaded connection and resist loosening.
