These heat exchangers have a broad temperature and pressure range and are used in single phase and two phase applications. They are able to handle many streams depending on the customers need. Pressures of up to 3625 psi can be handled sufficiently. The materials of construction of this exchanger include austenitic steels, aluminum alloys, carbon steel, nickel and chrome/moly alloys. This wide range of materials and the special features associated with the geometry of the heat exchanger allow for a wide range of applications.
The surface area of heat transfer can be as high as 20,000 m2 but the maximum diameter is limited to 7,500 mm and a weight of approximately 260 tons per unit. It is possible to have larger diameters or higher weights but their feasibility has to be checked depending on the customer’s needs.
The material of construction chosen depends on the customer’s needs. Simulations are The exchanger consists of a center hollow tube with tube bundles that spiral round it. The center tube and the tube bundle are housed in a metal column. The outer column does not have a uniform diameter. The bottom part has a larger diameter than the top part. Figures A and B show the outer shell and the tube bundles respectively. used for strength calculations of pressure containing vessels. Features such as tube spacing, tube support, bundle support and flexible mandrel are selected based on proven design technology developed over many years.
