Abstract:
1. An apparatus consisting of: a pressure container having an interior cavity fabricated from a cavity material and an outer surface spaced away from said interior cavity; a cryogenic gas in said interior cavity, external components outside of said pressure container; an internally threaded opening in said pressure container connecting said interior cavity to said external components, said opening having an end interfacing with said outer surface of said pressure container; and an insert threaded into said opening; a weld proximate said end of said internally threaded opening extending circumferentially around said insert, said weld located between said outer surface of said pressure container and said insert providing a seal between said outer surface of said pressure container and said insert; an inlet port tube connecting the external components with said interior cavity; an inlet port tube opening in said insert with said inlet port tube positioned in said inlet port tube opening; a circumferential inlet port tube weld connecting said inlet port tube to said insert that provides a seal between said inlet port tube and said insert; an outlet port tube connecting said interior cavity with the external components; an outlet port tube opening in said insert with said outlet port tube positioned in said outlet port tube opening; and a circumferential outlet port tube weld connecting said outlet port tube to said insert that provides a seal between said outlet port tube and said insert; wherein said circumferential inlet port tube weld is directly exposed to said cryogenic gas in said interior cavity and said circumferential outlet port tube weld is directly exposed to said cryogenic gas in said interior cavity.
