Plate heat-exchange apparatuses.

Apparatuses of plate heat exchangers with heat exchange surface area from 0,016 to 2000 m2, operating under pressure not more than 21 MPa, vacuum with absolute pressure not less than 665 Pa (5 mm Hg) or without pressure (under filling) and at wall temperature not less than minus 70 and not more than plus 650 °?*. The apparatuses are designed for heat exchange processes between liquids, gases, vapours and disperse systems at convective heat exchange, condensation or boiling of working media for application as coolers, heaters, recuperators, condensers, evaporators. When manufacturing apparatus for offshore floating oil and gas production complexes (FOC), floating drilling rigs (FDR) and offshore fixed platforms (OSP), heat exchangers are subject to technical supervision of the Russian Maritime Register of Shipping (hereinafter - the Register).
