FIELD: oil and gas industry.
SUBSTANCE: suggested device for reduction of a pipeline corrosion rate by means of electrostatic charge removal consists of a body mounted at the pipeline by means of a flange connection with a discharge electrode installed in it in the form of needles; according to the invention discharge electrodes are made as a screw, bushings and needles of chrome-nickel steel; they protrude from polyethylene isolation into emulsion flow, they are installed radially in three rows at the angle of 45 degrees and clamped by steel semi-rings and electrostatic charges are carried off through a drain cable to the ground conductor.
EFFECT: increase in performance, reduction in redistribution of electrostatic charges between the pipeline and oil, reduction of the pipe steel corrosion.
