US Patent 11174695 Integrated function block for use in subsea systems

An integrated function metallic block is capable of integrating into a single metal block the functions of valve blocks, block of hydraulic components of the pumping system, channels for transporting produced and separated fluids, flanges for choke connections and sensors, connection fittings and other components capable of being manufactured mutually within a single metallic block. The integrated function block is composed of complex geometry circuits having curves, slants and connections with other channels occurring within the block mass, and is preferably manufactured through the powder metallurgy process of hot isostatic pressing to obtain complex geometries having the lowest possible weight.
