Abstract

Fluid containing contaminants may be filtered using a hydraulic control line filter for subsea high-pressure application comprising a housing, an end cap disposed at a first end of the housing where the end cap defines a filter fluid connector which comprises a fluid inlet and a filtered fluid outlet, a first centralizer disposed within the housing, a sump tube disposed within the housing and centralized within the first centralizer where an outside diameter of the sump tube and an inside diameter of the housing define a sump volume annulus there-between, a filter centralizer, and a fluid filter disposed in the housing and centralized within the sump tube by the filter centralizer.
