Heat exchange assembly for ultra-pure water

摘要: A heat exchange assembly for raising a process fluid, such as ultra-pure, de-ionized water, to an elevated temperature without adversely affecting the quality thereof includes coaxially-arranged inner and outer pipes, annular space therebetween defining flow passage fluid be heated. The pipe is formed of high-strength metal good thermal conductivity encloses source, steam, circulating heated or electric heater. ensheathed by extruded heat-shrinkable plastic tube non-reactive material, PTFE polypropylene not exceeding 7 mils in thickness, which shrunk-fit thereon form one wall passage. opposing interior surface also constituted material polypropylene. Terminations comprising all-plastic unions are provided at ends pipes couple passageway inlet outlet fitting fluid. may reinforced braided sleeve.
