High temperature remotely connected/disconnected pipe connector for molten salt reactors

A pipe connector, comprising:

• a cylindrical pin defining a passage therethrough, the pin comprising:
• a first portion, a second portion, and a transition portion extending from the first portion to the second portion, the transition portion having a plurality of first threads extending outwardly from an outer surface of the transition portion, and the second portion having a plurality of second threads extending outwardly from an outer surface of the second portion;
• and
• a ledge extending inwardly from an internal surface of the pin where the transition portion and the second portion meet, the ledge defining a groove therein;
• a cylindrical seal ring defining a passage therethrough and comprising a first ridge and a second ridge extending outwardly from an outer surface of the seal ring, the first ridge being parallel to the second ridge, the seal ring inserted within the pin wherein the ledge is positioned between the first ridge and the second ridge, the passage of the seal ring being aligned with the passage of the pin;
• a retainer ring positioned within the groove formed in the ledge and surrounding the outer surface of the seal ring;
• a cylindrical box having a first end and a second end and defining a passage extending therethrough and a plurality of threads extending outwardly from an outer surface, the box defining a groove formed at the first end, the first end of the box inserted into the pin wherein the first end surrounds a portion of the seal ring and is positioned between the seal ring and the pin, the passage of the box being aligned with the passage of the seal ring;
• a cylindrical locking nut defining a passage therethrough and comprising a plurality of threads extending inwardly from an internal surface of the locking nut, the locking nut positioned around the pin and the box and being threadedly coupled to the plurality of first threads and the plurality of second threads;
• and
• a cylindrical retainer nut defining a passage therethrough and comprising a plurality of threads extending inwardly from an internal surface of the retainer nut, the retainer nut positioned around the box and being threadedly coupled to the plurality of threads of the box.
