СПОСОБ АНТИКОРРОЗИОННОЙ ЗАЩИТЫ МЕТАЛЛИЧЕСКИХ ТРУБОПРОВОДОВ ОТ ВНУТРЕННЕЙ КОРРОЗИИ

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to anticorrosion protection of metal pipelines for preventing corrosion destruction of their interior surfaces and can be implemented to reduce accident rate at operation of pipelines transporting corrosion-aggressive substances. The method includes reduction of bacterial and physics-chemical activity of transported corrosion aggressive product and its sedimentations on the interior surface of the pipeline by means of effect of magnetic field; also perpendicular directed alternating electromagnetic field is effected onto protected section of the metal pipeline. ^ EFFECT: upgraded resistance of metallic pipeline to interior corrosion. ^ 1 ex, 1 dwg
