The protection of tubing pipes from corrosion destruction is now becoming especially important. In world practice, one of the promising directions for preventing corrosion damage is the use of protective coatings for couplings. The choice of the method of applying a protective coating is an important step in ensuring the long-term operation of tubing. The wrong choice of the type of coating leads to additional operating costs. Among the existing methods of protection against corrosion, the operation of couplings with a protective thermal diffusion zinc coating is relevant, which makes it possible to increase the operational reliability and service life of tubing couplings and provide protection for the “pipe-coupling” threaded connection. This article presents the results of a comprehensive assessment of the properties of a protective coating applied by the method of vapor-phase thermal diffusion galvanizing on couplings for tubing in the conditions of “KSP Steel LLP”. In the course of the work, the properties of the coating were determined, which ensure the corrosion resistance of metal products. Methods of assessment are stated and the results of studies of technological, operational and physical-mechanical properties of the coating are presented. The results of the study of the technological, physical-mechanical and operational properties of the coating showed that the properties of the coating that provide corrosion resistance, such as: thickness, wear resistance, adhesion strength of the coating to the surface of a metal product, porosity, corrosion protection properties correspond to the normalized values.
