Abstract
A pipe connection for conducting a fluid that is under pressure is provided, having two tubular connection parts for a conical clamping connection, which are screwed together by a union nut while one is inserted in the other, wherein each connection part has a conical sealing surface that contacts the other in a sealing manner and wherein an annular groove is provided in one of the sealing surfaces. In order to enable the pipe connection also to conduct a fluid having cycling or varying temperature, the inner of the two connection parts has thermal insulation on the inside of the pipe at least in the axial segment of the sealing surface of the connection part, wherein the thermal insulation tube has a cam or a collar on the outer surface, which engages in a recess, which is axially bounded by the two connection parts.
