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.

A stationary gas turbine having at least one at least partially annular gas supply line, which is supported by a retainer, wherein the gas turbine has in the interior thereof a main flow direction of the working fluids, and wherein the retainer has at least one floor retainer supported against the floor and a face retainer attached to the housing of the gas turbine on the side opposite the floor retainer, and wherein both the floor retainer and the face retainer support the gas supply line against motion both in the main flow direction and perpendicularly thereto, wherein the face retainer has a spring system, which in particular compensates the change in the extent of the housing during operation of the gas turbine.

A pipe connection arrangement in a high-pressure fluid line system of a dual fuel engine, having first pipe element with outer sealing cone and conical shoulder adjoining the cone, having further pipe element with inner sealing cone and external thread, having a screw nut element with clamping sleeve region having inner clamping cone and threaded sleeve region having internal thread. The outer sealing cone of the first pipe element is arranged in the inner sealing cone of the further pipe element and the internal thread of the screw nut element is screwed on the external thread of the further pipe element. The inner clamping cone of the screw nut element is pulled against the conical shoulder of the first pipe element such that the outer and inner sealing cones are clamped with one another in a sealing manner, wherein the threaded sleeve region of the screw nut element is conical.

A fuel line of a turbo-machine having a conical screw connection, wherein the conical screw connection has at least one screw socket into which a sealing cone having a sealing cone surface and a sealing cone face of a screw connection body connected thereto is interlockingly inserted, and screw socket and screw connection body are directly or indirectly screwed to each other, wherein the sealing cone has a metallic, flat sealing element which is received in a receptacle of the sealing cone surface, wherein the flat sealing element is a metal which is softer than the material of the sealing cone.
