1. A flange adapter apparatus for attachment to a housing at a flange of the housing wherein the apparatus secures a flow line to the housing at a housing flow aperture to allow fluids to travel through the housing and horizontally through the flow line, wherein the flange adapter aligns with a housing alignment indicator for proper orientation of the apparatus when secured to the housing, the apparatus comprising:

  • an attachment body attachable to the housing near the housing flow aperture;

    a first attachment aperture located on the attachment body, the first attachment aperture configured to accept a fastener to secure the attachment body to the housing;

    a second attachment aperture located on the flange adapter wherein the second attachment aperture is located laterally interior of the first attachment aperture, the second attachment aperture configured to accept a fastener to secure the flow line to the flange adapter;

    an adapter flow aperture of the flange adapter, the adapter flow aperture located interior of the first attachment aperture and the second attachment aperture, wherein the fluids travel horizontally through the adapter flow aperture from the housing to the flowline;

    an outer edge of the attachment body encompassing the adapter flow aperture to direct all fluid passing through the flange adapter through the adapter flow aperture;

    a flattened section of the outer edge defined by the outer edge of the attachment body;

    a curved section of the outer edge defined by the outer edge of the attachment body wherein the curved section is located radially outward from the adapter flow aperture wherein the flattened section is located nearer the adapter flow aperture than the curved section;

    a rear surface of the attachment body wherein the rear surface is located adjacent the housing when the flange adapter attaches to the housing;

    a first seal base encompassing the adapter flow aperture on the rear surface of the attachment body, wherein the first seal base accepts a seal;

    a housing seal base on the housing wherein the attachment of the attachment body to the housing aligns the first seal base with the housing seal base; and

    an adapter alignment indicator located on the attachment body, the adapter alignment indicator distinct from the first attachment aperture and the second attachment aperture wherein alignment of the adapter alignment indicator with the housing alignment indicator orients the flattened section of the attachment body to be installed as a lowest surface of the attachment body secured to the housing for the fluids to flow horizontally through the adapter flow aperture to the flowline.
