FIELD TESTABLE INSTRUMENT HOUSING CONNECTION

摘要

A field testable instrument housing connection is made up of an integral instrument housing assembly that includes both an instrument housing and a separate one-piece compression nut portion and a separate modified reducing union. The instrument housing has a mating geometry that is disposed over the downhole portion of the separate modified reducing union and the separate one-piece compression nut portion is then disposed over both the uphole portion of the instrument housing and a downhole portion of the modified reducing union. The complete assembly of the modified reducing union, including primary and secondary seals in combination with the integral instrument housing assembly provide then both an annular seal and a seal of the instrument housing. The entire assembly is field testable via provided test ports.
