PRODUCTION OF POWDERS FOR THE MANUFACTURE OF A CORROSION LAYER OF BIMETALLIC PIPES IN ARCTIC OIL AND GAS FIELDS

The increased corrosive aggressiveness of the pumped media is one of the modern challenges in oil production and primary fluid processing. One of the ways to increase the equipment resistance to corrosion damage is the use of stainless steels or bimetallic materials in devices that come into contact with aggressive liquids. The aim of this work was to study the effect of the technological parameters of spraying on the granulometric composition and properties of powders 08Cr18Ni15, 07Cr16Ni6 and 08Cr17Ni22 for spraying bimetallic materials onto the welds. According to the research results, the possibility of using stainless steel powders for applying protective anti-corrosion coatings by plasma spraying onto welded joints of components and structures of technological equipment at oil producing enterprises was confirmed.
