Information × Registration Number 0210U003979, 0107U008872 , R & D reports Title Increase in a resource of work of lengthy pipelines (l/d >100) of steam generators of the atomic power station by coatings on internal surfaces of pipes which made out of chromium carbid or oxid aluminium oxid with high corrosion resistance which obtained by thermal. popup.stage_title Head Shirokov Boris Mkhajlovich, Доктор технічних наук Registration Date 13-04-2010 Organization National Science Center "Kharkiv Institute of Physics and Technology popup.description2 It was received the coatings on internal surfaces of breadboard models of pipes and it was shown an opportunity of carrying out of processes on lengthy tubes l/d> 100. The rate of sedimentation of a coating for the given length of a heater allows to deposit a coating at thickness of 10 microns with a speed 500 microns/hours and above. Application of this technological process probably, except for atomic engineering, in such areas, as chemical, petrochemical, oil refining and other areas which require protection of internal surfaces of the equipment working in conditions corrosive and erosive deterioration. Technological process of sedimentation of coatings on internal surfaces of heat exchanging pipes in diameter of 16 mm prototype models is fulfilled. It is deposited protective chromium carbide coatings on internal surfaces of breadboard models of heat exchanging pipes. Absence of through porosity in such coatings is reached at thickness of 15 microns. The given coatings have shown high stability in the environment of the heat-carrying agent at temperature 350°С and pressure 15 MPa during autoclave tests. The technological scheme of installation, recommendations and requirements for creation of the multipurpose installation for increasing productivity of the suggested scheme is offered.
