HIGH FATIGUE LIFE FITTINGS FOR HIGH-PRESSURE FLUID SYSTEMS

摘要

A fitting (120) for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting (120) includes a body (122), and a plurality of apertures (124) formed in the body (122) in a common plane, intersecting inside the body (122) such that all of the apertures (124) are in mutual fluid communication. Each of the apertures (124) is configured to receive a threaded coupling member of a respective high-pressure transmission line. The fitting (120) also includes first and second compression members (132) positioned on opposing sides of the body (122) and coupled thereto so as to exert a compressing bias to the body (122) in an axis perpendicular to the common plane. The compression members (132) each comprise a raised contact surface (135) corresponding to the region of the body (122) where the plurality of apertures (124) meet, and through which the compressing bias is exerted. The fitting (120) may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.
