DEVICE FOR DETECTION OF DEFECTS IN PIPELINES OF UNDERGROUND HEAT NETWORKS

摘要

A device for detection of defects in pipelines of underground heat networks relates to heat engineering and can be used for determination of location of defects in heat networks of channel-less laying with pipelines in foamed polyurethane insulation. Use of the device makes it possible to detect defects of the body of pipeline and its insulation in heat networks of channel-less laying with pipelines under conditions of effect of acoustic and electromagnetic noises.
