Possibility of Heating System Pipeline Corrosion Investigation with Electrometrical Methods

P142 POSSIBILITY OF HEATING SYSTEM PIPELINE CORROSION INVESTIGATION WITH ELECTROMETRICAL METHODS 1 Coated steel underground pipelines are widely used in the municipal heat supply. The soils where the pipelines are placed are usually highly corrosive for pipe’s metal. In the places of crippling of external coating the corrosion processes begin and this can provoke a pipe breakage. To ensure the pipeline survivability it is necessary to carry out the control of pipeline conditions. The electrometric methods are widely used in world-wide practical work. Authors have studied the corrosion processes of the municipal heating system pipelines in Saint-Petersburg (Russia) using a
