Split flange retainer for flanged conduits

A split flange retainer assembly for making a fluid tight sealed connection to a bulkhead or the like, comprising:

• a conduit of a given diameter and having a flanged head and seal means interposed between the head and bulkhead for enabling the sealed connection;
• a pair of interconnecting flange segments having mating overlapping portions, said flange segments having inner arcuate surfaces with stepped shoulders and having an arc length greater than 180.degree. and extending about the periphery of the conduit and the shoulder of the flange segments bearing against the flanged head of the conduit;
• said inner arcuate surface of each of the flange segments terminating in respective first and second arc tips, the distance between the first and second arc tips being less than the diameter of the conduit;
• each of said flange segments including four openings, two of the openings being full bores penetrating the flange segments and the other two openings being semi-bores positioned at each of said first and second arc tips;
• means for fastening through the openings the interconnected segment to the bulkhead and forming the sealed connection;
• and
• said interconnecting flanged segments, in assembly with the conduit, being interlocked so that the flange segments cannot be pulled radially apart.

A split flange retainer half for use in engaging the flanged head of a conduit having a given diameter, for coupling the same, comprising:

• a body portion of a given thickness and having an inner curvilinear surface defined by adjacent upper and lower circular arcuate surfaces joined by a stepped shoulder, the shoulder adapted to engage the flanged head of the conduit;
• first and second legs, of lesser thickness than the body portion and attached to and extending away respectively from each end of the body portion, each leg having an inner circular arcuate surface smoothly and continuously extending from at least one of said upper and lower arcuate surfaces of the body portion along the same circular arc defining said upper and lower arcuate surfaces;
• said body portion together with the marginally extending first and second legs together having a curvilinear inner circular arcuate surface characterized by an arc length greater than 180.degree.;
• a plurality of openings in the split flange retainer half for receiving fastener means for coupling the flanged head of the conduit;
• and
• at least one of said openings including a through bore and a semi-bore axially interconnected and formed at the juncture between the body portion and at least one of said legs.
