IDEA #8G5ISS System Of Corrosion Monitoring Of Pipelines (Scmp)

SYSTEM OOFF CORROSION MONITORING ooff PIPELINES ((SCMP)) APPLIEDRESEARCH • SENSORSDescription In a corrosion laboratory of the E.O. Paton Electric Welding Institute the system of corrosion monitoring of pipelines (SCMP) was designed. Due to SCMP it is possible to measure of instantaneous corrosion rate of the pipeline metal from an external and internal surface of the pipeline, values of electro(cid:2) chemical potentials (polarization potential, corrosion poten(cid:2) tial, summary potential with ohmic component, transversal and longitudinal potential gradients through the length of the pipeline). A measuring block (MB) with GPS system, interrupters of a cathodic protection current ICPC(cid:2)30, spool of a wire (1000 m) with the counter of metric area, copper(cid:2)sulphate reference electrodes, corrosion rate sensors, device for embedding of the corrosion rate sensors enters to the structure of SCMP. Innovative Aspects and Main Advantages First the system which allows simultaneously determine time , corrosive of a soil and transported product, damaged areas of a protective coating, residual corrosion rate of pipeline metal in a protective coating defect, defending degree of the pipeline on extension and in time, the presence of wandering earth currents. Analogues of an offered system are the products developed by German corporation "Weilekes elektronik ", the American cor(cid:2) poration "Magna Corporation", Russian SAS "ASIIGAS", the Dutch corporation "Scan". However apparatus mentioned above do not allow carrying out measurement of instanta(cid:2) neous corrosion rate and residual corrosion rate of the pipeline metal in defects of an insulation cover. Area ooff Application Oil(cid:2)gas complex manufactures, ammonia manufactures, municipal services of water(cid:2)supply and gas(cid:2)supply. Stage ooff development SCMP was tested, it is accessible for demonstrating (cid:2) the field tests were carried out. There is an experimental sample of SCMP. Fig. 1.
