QUALITY CONTROL OF STRUCTURAL CHANGES IN ZONES LOCALDESTRUCTION PIPELINE SYSTEMS OIL PRODUCTS
(pp. 69–75)

Annotation. Found that the most dangerous type of corrosion is pitting TSPN. Macrostructure studies and electronic fractography established presence on the inner surface of solid samples dense black deposits. Chemical analysis showed that deposits are the products of sulfide corrosion also revealed elevated mobile hydrogen in the metal. Based on the volume and thickness measurement of the results of measurements of the coercive force, the mechanism of local catastrophic corrosion of TSPN. A method of non-destructive quality control of welding and subsequent heat TSPN, which will prevent accidents

Keywords: corrosion, micro-and macro-structure, cavitation, thickness, coercive force, sulfide deposits
