Abstract
Изобретение относится к электрохимической защите объектов от коррозии, а именно к способам и устройствам катодной защиты промысловых и магистральных нефтепроводов и нефтепродуктопроводов. Согласно предложенному способу, трубопровод для транспортировки жидких углеводородов заземляют, к его наружной поверхности подводят ток от внешнего источника постоянного тока. Сдвигая потенциал металла пропусканием внешнего электрического тока, замедляют скорость его коррозии. Для дополнительного подвода отрицательных электрических зарядов к стенкам трубопровода, к трубопроводу для транспортировки жидких углеводородов подсоединяют лупинг - дополнительный трубопровод, параллельный основному, внутри которого устанавливают трибогенератор, который состоит из блока дисков с перфорацией в виде резьбовых отверстий, жестко закрепленных на равных расстояниях друга от друга на центральной штанге (10). Все детали блока дисков изготавливают из алюминиевого сплава, имеющего значение стандартного электрохимического потенциала меньшее, чем у железа. Испытания показали, что защита трубопроводов согласно предложенному способу в сравнении с известным позволяет в 2-5 раз замедлить все коррозийные процессы (не более 10 мкм в течении года).The invention relates to the electrochemical protection of objects from corrosion, and in particular to methods and devices for cathodic protection of field and trunk oil pipelines and oil pipelines. According to the proposed method, the pipeline for the transportation of liquid hydrocarbons is grounded, current from the external source of direct current is supplied to its outer surface. Shifting the potential of the metal by passing an external electric current, they slow down the rate of its corrosion. For an additional supply of negative electric charges to the pipeline walls, a looping is connected to the pipeline for transporting liquid hydrocarbons - an additional pipeline parallel to the main one, inside which a tribogenerator is installed, which consists of a block of disks with perforations in the form of threaded holes fixed at equal distances from each other on the central rod (10). All parts of the block of disks are made of an aluminum alloy having a standard electrochemical potential value less than that of iron. Tests have shown that the protection of pipelines in accordance with the proposed method, in comparison with the known method, makes it possible to slow down all corrosive processes by a factor of 2-5 (no more than 10 microns within a year).
