  • Method and apparatus for mounting an instrument assembly on a main flow line
    Patent number: 5292155
    Abstract: A stabilized connector assembly (24) for connecting an instrument manifold (26) to an orifice fitting assembly (16) for a main flow passage (10) comprising a pair of generally identical stabilized connector subassemblies (30, 32). Each subassembly (30, 32) includes an elongate connector body (34) having an externally threaded inner end (38) for threaded engagement with an internally threaded outlet port (24) of the orifice assembly (16) and a flanged outer end (40). Bolts (58), jack nuts (68), and collar (78) form stabilizing components connected between the outer flange (40) and the orifice assembly (16) for resisting radial loads from a manifold (26) thereby minimizing any deflection of connector body (34) and resulting stress at inner threaded end (38).
