The Shell and Tube Type Heat Exchanger consists of two sides for two different media.
The Shell Side fluid flows on the outside of the tubes while the fluid is contained by the shell where it is diverted by baffles or tube supports that also carry the weight of the tubes. The Tube Side media flows inside the tubes while the media is diverted by the heat exchanger head which is located on the end into two or four passes or circuits.
DFC could comply with ASME code, TEMA standard to design and manufacture heat exchangers for petrochemical, fertilizer,coal chemical, power plant, steel industries. The material could be stainless steel, titanium,carbon steel,duplex steel.
