PIPE CONNECTION FOR FLUID PRESSURIZED FILTERING Russian patent published in 2017 - IPC F16L59/18 

Abstract RU 2633231 C2

FIELD: construction.

SUBSTANCE: invention relates to a pipe connection (10) for conducting a pressurized fluid including two tubular connecting parts (12, 14) for a conical clamping junction (16) that, when inserted into one another, are screwed together by a union nut (28). Each connecting part (12, 14) has a conical sealing surface (20, 22) adjacent to the other with a seal. An annular groove (26) is provided in one of the sealing surfaces (20, 22). To provide a sealed pipe connection (10) suitable for conducting a fluid with a varying temperature, it is proposed that one of the two connecting parts (12) located inside has at least in the axial portion of its sealing surface (20) inside the pipe thermal insulation, advantageously in the form of a heat-insulating pipe (30), and that the heat-insulating pipe (30) has a protrusion or collar (38) entering the recess (40) which is axially bounded by both connecting parts (12, 14) on the side of the side surface.

EFFECT: increased reliability of connection.
