Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.

Heat exchanger for quenching reaction gas comprising a coolable double-wall tube including an inner tubular wall and an outer tubular wall, wherein said inner tubular wall is configured to convey said reaction gas to be quenched, and wherein a space defined by said inner tubular wall and said outer tubular wall is configured to convey a coolant; a tubular connection member having a bifurcating longitudinal cross-section comprising an exterior wall section and an interior wall section defining an intermediate space filled with refractory filler material, wherein a converging end of said connection member is arranged to be in connection with an uncoolable reaction gas conveying pipe, wherein said exterior wall section is connected with said outer tubular wall of said coolable double-wall tube, wherein an axial gap is left between said interior wall section and said inner tubular wall of said coolable double-wall tube.

A device is for clamping one or more inserts arranged outside pipes during the assembly of pipes for pipelines serving to transport oil, gas or water. The device has a clamping device which at least partially encloses the inserts with a slot with a length-stable layer arranged against a flexible tube on a side of the layer such that a flexible tube arranged in the layer follows the slot. The layer is coupled to the flexible tube and ends of the length-stable layer have end pieces of a length configured in or around the inserts and/or the slot such that the end pieces of the length-stable layer are prevented from displacement relative to the inserts. The flexible tube is supplied with a medium that can be pressurized and/or cured in an expanded state between the length-stable layer and the inserts without increasing a nominal diameter of length-stable layer.

Specified is an arrangement for supplying power to a motor vehicle which is equipped with an electric motor and in which there is arranged at least one rechargeable electric battery to which the electric motor is connected. The arrangement includes a stationary charging station which is equipped with an electric power source and to which an electric line having at least two mutually insulated electrical conductors is connected, a part of an electrical coupling for connecting to a complementary coupling part present on or in the motor vehicle being attached to the free ends of said electrical conductors, said coupling part being connected to the battery in an electrically conductive manner. The electric line is surrounded along its entire axial length by a thermally insulated and flexible tube made of metal which is closed all around and which, in addition to the line, encloses a cavity along its entire axial length. A flowable medium refrigerated to a temperature of at least 160 C. is contained in the space enclosed by the tube, and a thermally insulated storage tank containing a store of the refrigerated medium is arranged in the charging station, the tube being connected to said storage tank.

A heat transfer element includes curved mounting surfaces configured to mate with an outer surface of a pipe for attachment thereto; and a channel configured to receive a tracer therein. The heat transfer element is configured to effect conductive heat transfer from the tracer to the pipe, or to process flowing through the pipe, when attached with heat transfer cement (HTC) to both the pipe and the tracer.
