CABLE MOUNTING EQUIPMENT IN HORIZONTAL PIPELINES AND LIQUID HEATING IN PIPELINES

摘要

FIELD: electricity.SUBSTANCE: system includes a heating cable, which is placed in the zone of possible wax formation or pipeline freezing, the transition terminal box for the heating cable connection, heating control station, the cable pusher, creates an additional stress for unwinding the heating cable from the technological drum and pushing through the inclined insertion in the pipeline, parasol-piston, which is mounted on the tip of the heating cable. Umbrella-pistal opens and creates pulling force under the action of the flow of the technological fluid and closes after cable mounting under the action of excess pressure in the pipeline. There are load-bearing core and separating bundles made of high-strength aramid fibers in the heating cable. There is an implemented automatic adaptive cable heating control system in the control station on the current values of the pressure and temperature of the fluid in the pipeline, as well as the system of remote control and cable heating control.EFFECT: simplifying the process and reducing cable installation time, implementation of the heating in automatic mode with minimal costs.3 dwg
