<p>An experimental rig made of silicate and brass tubes of a "double-pipe heat exchanger" type has been developed to study the corrosion process and scale formation. Experimental studies have shown that the rates of corrosion of silicate coatings of heat exchange tubes increase linearly with an increase in the speed of seawater movement. It has been established that the rates of corrosion of silicate coatings of heat exchange tubes do not exceed 0.020 g/(m²·day). During long-term tests of silicate coatings of tubes, on the surfaces of the latter insignificant scale deposits are formed, the thickness of which is within 0.14–0.23 mm, while on the metal surfaces of the tubes a strong layer of scale and corrosion products with a thickness of 1.24–1.98 mm is formed. The conducted studies have shown that in silicate coatings of heat exchange tubes the increase in the heat transfer coefficient is approximately 12–25%, depending on the operating conditions and the technological mode of the apparatus.</p>
