摘要： The invention relates to a pipe connection (10) for conducting a fluid that is under pressure, comprising two tubular connection parts (12, 14) for a conical clamping connection (16), which are screwed together by a union nut (28) while one is inserted in the other, wherein each connection part (12, 14) has a conical sealing surface (20, 22) that contacts the other in a sealing manner and wherein an annular groove (26) is provided in one of the sealing surfaces (20), (22). In order to enable the pipe connection (10) also to conduct a fluid having cycling or varying temperature, according to the invention the inner of the two connection parts (12) has thermal insulation, preferably in the form of a thermal insulation tube (30), on the inside of the pipe at least in the axial segment of the sealing surface (20) of said connection part, wherein the thermal insulation tube (30) has a cam or a collar (38) on the outer surface, which engages in a recess (40), which is axially bounded by the two connection parts (12, 14).
