Abstract: As the name implies Heat exchanger, Heat (hot) and exchanger. Heat Exchanger is a vessel which serves to transfer heat from one fluid to another fluid phase either one or many phases. One type of heat exchanger is a shell and tube type, This type of shell and tube itself has many models and types, one type of BEM (TEMA). BEM type has a simple design and not too complicated when compared with other type exchanger. In general, engineering design using standards as the basis for the analysis of the design calculations in the design process. Although in fact the standard can not be said to be a real source in doing the design of equipment. Thus it is necessary for comparison between fundamental analysis with the mechanical design. It is used to find out how much the level of security and efficiency are given on the method of fundamental analysis and mechanical design. In the process of comparison (Comparing) mechanical design with fundamental analysis, the comparison includes the value of the thickness, longitudinal stress, tangential stress, and the accretion radius due to deflection that occurs on parts of the BEM type heat exchanger in both the operating pressure conditions (pressure operation) and on the conditions design pressure (design pressure) From the design results are calculated the average difference in thickness values at design conditions is 0.176 in. and at the operating condition is 0.131 ins. Percentage increase in value of the thickness of the mechanical design of the fundamentals of design at the design condition is 43% and at operating conditions is 38%. viii The average value of the percentage of longitudinal stress values (the design pressure) in new condition which is 29% and the corroded condition of 48%. At the time of the operation pressure, the average percentage of the value of longitudinal stress on the new conditions of 16% and the corroded condition of 49%. An increase in the value of the tangential stress on the mechanical design of the fundamental design (design pressure conditions), the average increase in value of the tangential stress on the new conditions at 29% and 51% corroded condition. Similarly, when the operation conditions of pressure, an increase in the value of the tangential stress on the mechanical design of the fundamental design, the average increase in value of the tangential stress on the new conditions of 17% and 52% in the corroded condition. Percentage of value-added radius due to deflection at the mechanical design of the fundamental design (on the condition of design pressure) is the new events on the condition of 27% and 25% corrosion. While on the operation conditions of pressure, the percentage of value-added radius due to deflection at the mechanical design of the fundamental design of the new conditions of 11% and the old conditions of 36%.
