EXPERIMENTAL STUDIES OF ANTICORROSION COATING EFFICIENCY

Abstract

The huge expenses of oil companies associated with corrosion of metal pipes led to the creation of metal pipes with high corrosion resistance. Coating of pipelines is performed for protection against corrosion, mechanical damage and other external impacts. There are several basic methods of coating pipelines, and the choice of method depends on the operating conditions, type of pipes, protection requirements and cost. The introduction of certain components into the metal and the observance of a certain technology of continuous steel casting makes it possible to obtain metal that is pure in terms of the content of impurities. Such a metal is distinguished by its strength, plastic and corrosion-resistant characteristics. The anticorrosive coating proposed by the authors effectively reduces the corrosion rate of stainless steel and provides a high degree of protection in salt media at various pH and temperature variations. The purpose of this section is to comprehensively evaluate the anticorrosive effectiveness of alkyd-urethane varnish and microsilica coating developed using examples of various types of tubular steels. Methods of simulation of aggressive corrosion conditions are used in the work, which make it possible to reproduce the actual operational factors and objectively assess the protective properties of coatings.
