Technical Examples

A jacketed pipe flange (10) for connection to an end of an inner pipe (12) and to an end of a jacketed outer pipe (14) surrounding the inner pipe includes a central throughport (16) for mating with the inner pipe. The first annular sealing surface (18) surrounds a central throughport for sealing fluid within the inner pipe, a second annular sealing surface (20) surrounds the first sealing surface, and a third annular sealing surface (22) surrounds the second annular sealing surface for sealing fluid in the jacketed outer pipe from the exterior of the flange. An annular gap (24) separates the first and second sealing surfaces, and a test port (26) fluidly connects the annular gap with an exterior port in the flange. A plurality of axially extending throughports (34) in the flange between the second and third sealing surfaces pass fluid through the jacketed outer pipe and the flange to downstream components.
