摘要

Principally new discrete intelligent corrosion control devices were developed. They consist of the an active element gathered the sheet pile form of isolated uniform steel plates with the sequential corrosive destruction of the each next plate starting from the external plate which contacts with corrosive environment. Every one of the plates is connected with the conductor which joins with the separate contact of the plug-type connection that intended for a connection with the analyzer or a pipeline. A memory unit which represents a printed circuit board with a memory chip is installed in the plug-type connection case. It keeps data of thickness and number of plates and data of corrosive processes dynamics over the operating period. The analyzer is the second part of the device.The analyzer does sequential scanning of plates after that corrosion rate's and depth's values are calculated and displayed. The analyzer contains a data storage element and an interface for computer communication by standard ports for the data transmission and processing. After the data transfer to the computer a specific program processes and puts out data about the underground structure corrosive condition: corrosion rate (mm/y), corrosion general depth after date of the active element installation in corrosive environment and full dynamics of corrosive behavior over the structure operation period. The cathodic protection efficiency estimation is carried out using two active elements - connected and disconnected to cathodic protection. The innovation passed through the laboratory and field tests in the course of three years. The anodic dissolution of active element plates was carried out for the conformance inspection of active element plates corrosion rate to registrations of the analyzer. The testing showed following results: the dissolution of plates occurred in consecutive order, the next "n+1" plate dissolved after the dissolution of the "n" plate; galvanic contact between plates under the dissolving plate is absent. It is evidence of hermiticity of the sensor in whole; the stationary potential or the natural corrosion potential set at every case on the expiry of anodic polarization that is corrosion processes occur at the plates, the plate is not passivated. Therefore the plate perforation can be evidence of the corrosion destruction depth in unit time; the corrosion destruction depth fixed by the analyzer corresponds to the plates real condition; the analyzer passed through the test on "scaning plates maximal number", interaction with a computer and correct data transfer to a computer. Field tests of the sensors was carried out at real medium of a pipeline occurrence for the refinement of testing results and data getting. Tests was carried out at operating gas pipelines in Russia and Ukraine. Also tests was carried out at pipelines with weight coating in the Moscow pipe-manufacturing plant. The tests shown that the active element represents adequately the real corrosion condition.
