^α^^Ύ «~f*—* WL·**"" calls for Carbon-Tube Where acids or acid solutions are to be heated with steam, or where heat must be transferred from liquid to liquid and either or both liquids are corrosive, Swenson Process Engineering frequently recommends the use of Swenson Heat Exchangers with carbon tubes. T h e s e H e a t E x c h a n g e r s have proved eminently successful in a great many applications because of their resistance to corrosion, low friction-

al resistance, high coefficient of heat transfer, and relatively low original and operating cost. They may be arranged for single or multi-pass operation, as desired. The tube sheet is usually fabri cated of lead, lead - covered steel, rubber-covered steel or corrosionresistant alloy — as conditions may require. If the liquid in the shell is corrosive, the shell also may be con structed of these materials.

Heat Exchangers The carbon tubes are not cemented to the tube (as is the case with most carbon-tube heaters), but are held in place by a patented Swenson tube anchorage consisting of a ring-gasketed joint (see illustration). This anchorage relieves the tubes of all stress caused by difference in expansion of the shell and the carbon tubes. Similar construction has been used for several years .in Swenson Evaporators for certain types of acid solutions. Let Swenson Process Engineering help you with problems involving heat transfer.
