Abstract
The hydrostatic test is performed on a computer model of a heat exchanger to see if there is any leakage in the heat exchanger. This test is performed on different parts separately based on the calculations specified in the book of ASME SEC VIII DIV-1 2007 ED. Maximum allowable pressure (MAWP) for different parts is determined and then is multiplied by a factor of 1.3. The test is then performed on different parts based on those values continuously for 30 minutes. This test easily tells where the leakage is which usually occurs in the joints which are welded. This test is performed along with FEA before installing the heat exchanger. Once the CAD model is developed, FEA is done to analyze the design thus saving money and time by reducing number of prototypes. Through FEA we can optimize the size so as to reduce the weight of heat exchanger. Through FEA we take a look at the entire design and understands how load is transferred between parts and also where critical areas of design are located. Thus we can test a design before actually building it, therefore saving the time and cost.
