Hydraulic control line filter for subsea high-pressure application
A recently filed patent (Publication Number: US20230265730A1) describes a hydraulic control line filter designed for subsea high-pressure applications. The filter consists of a housing with an inner cavity and a pressurized fluid inlet, an end cap with a filtered fluid outlet, a first centralizer within the housing cavity, a sump tube centered within the housing, a filter centralizer within the sump tube, and a fluid filter within the sump tube. The filter is capable of handling fluid pressures of up to 15,000 psi.
The first centralizer in the filter is conical in shape and guides pressurized fluid to the periphery of the sump tube. The filter is primarily designed for use in a surface control subsurface safety valve (SCSSV). The housing, first centralizer, sump tube, filter centralizer, and fluid filter are all tubular in shape. The end cap has a threaded portion, and the sump tube has multiple ports that allow fluid to enter the filtration area defined within the filter.
The method of filtering fluid using this hydraulic control line filter involves accepting pressurized fluid through the inlet, diverting it to the sump tube using the first centralizer, collecting the fluid in the sump tube, allowing sediments to settle, and then filtering the fluid using the fluid filter. The filtered fluid exits through the filtered fluid outlet in the end cap.
The filter components are connected through welding, with the fluid filter connected to the end cap and filter centralizer, the sump tube fitted over the end cap and connected to the first centralizer, and the housing fitted over the end cap using threaded connectors. A groove weld is created between the housing and the end cap to ensure a seal.
Overall, this patent describes a hydraulic control line filter specifically designed for subsea high-pressure applications. The filter's unique design and method of operation allow it to effectively filter fluid at high pressures, making it suitable for use in various industries, particularly in subsea environments.
