Subsea hydraulic control line filter for high-pressure applications
The patent US11988061B2 describes a hydraulic control line filter specifically designed for subsea high-pressure applications, capable of operating under pressures of up to approximately 15,000 psi. The filter comprises a housing with an inner cavity and a pressurized fluid inlet, an end cap with a filtered fluid outlet, and a sump tube centered within the housing. Key components include a first centralizer that directs fluid flow, a filter centralizer, and a fluid filter that is positioned within the sump tube. The design incorporates multiple ports on the sump tube to facilitate fluid entry and sediment settling, ensuring effective filtration of contaminated fluids.
Additionally, the claims detail the structural features of the filter, such as the tubular configuration of its components, the inclusion of clamps for stability, and the use of porous sintered metal for the fluid filter. The method of operation involves accepting pressurized fluid, diverting it through the centralizer, and allowing sediments to settle before filtering the fluid through the filter. The assembly process is also outlined, emphasizing the use of welds and threaded connectors to secure the components. This innovative design aims to enhance the reliability and efficiency of fluid filtration in challenging subsea environments.
