Problems solved by technology

In order to avoid mechanical overloading stresses (Ueberlastspannung) due to this thermal expansion, compensating elements, such as U-shaped arcs (U-Boegen), are installed in the pipe thread (Rohrleitungsstreck), which is expensive and often also leads to current losses in the line

Embodiment Construction

[0013] figure 1 The basic configuration of the device used to prepare the pipeline is shown. An electric heater 1 is provided, which is connected via a power connection cable 3 to an energy supply source 2 , for example an electrical grid, and which is connected on its side to a medium line 6 via heating current lines 4 , 5 . In the embodiment shown, the pipeline 6 is divided into individual conductor segments 61, 62, 63, 64, wherein the segments 61 and 63 to which the heating current lines 4 and 5 are connected are connected to each other by a bridge line 7 for connection to the conductor Segments 4, 61, 7, 63 and 5 form a current loop.

[0014] The medium line 6 generally comprises a steel pipe as a structural part, and a housing made of an insulating material which is not only electrically but also thermally insulated. A sensing line 8 extends inside the isolated part, and a temperature sensor 9 is connected to the sensing line 8 . The heater 1 has a sensing line 10 whic...

Abstract

An arrangement used to prepare the conduit wiring (6), the conduit wiring includes the conductor section (61, 62, 63, 64) which is electricity-insulated and heat-insulated, and is heated for a short time or continuously with special heater (1). The special heater (1) includes an energy-supplying connecting part (14), a temperature sensing part (13), a control unit (12) and a heating current emitting part (19). The control unit (12) is provided with a heating current regulator, to heat up the conduit wiring (6) to the proper temperature.

Description

technical field [0001] The invention relates to a device for producing a pipeline (Rohrleitung) comprising electrically and thermally isolated conductor sections (Leiterabschnitte). Background technique [0002] During the laying of the heating system lines (Fernheizungsrohrleitung), these pipes are exposed to the ambient temperature so that the corresponding line section (Rohrleitungsabschnitt) has a defined "cold length (Kaltlaenge)". During operation of heating system lines, a temperature rise occurs and this leads to a lengthening of the line section ("warm length"). In order to avoid mechanical overload stresses (Ueberlastspannung) due to this thermal expansion, compensating elements, such as U-shaped arcs (U-Boegen), are installed in the pipe thread (Rohrleitungsstreck), which is expensive and often also leads to current losses in the line . Contents of the invention [0003] The object of the present invention is to provide a device for the production of pipelines...
