MECHANICAL DESIGN OF HEAT EXCHANGERS

Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function. What is shell and tube heat exchanger?What is shell and tube heat exchanger?The shell-and-tube heat exchanger is named for its two major components round tubes mounted inside a cylindrical shell. The shell cylinder can be fabricated from rolled plate or from piping (up to 24 inch diameters).Shell and Tube Heat Exchangers Construction Details What is the temperature of a heat exchanger?What is the temperature of a heat exchanger?The shell-and-tube heat exchanger is by far the most common type of heat exchanger used in industry. It can be fabricated from a wide range of materials both metallic and non-metallic. Design pressures range from full vacuum to 6,000 psi. Design temperatures range from -250 oC to 800 oC.Shell and Tube Heat Exchangers Construction Details

1.2 The high-temperature properties of the materials covered in this specification are dependent upon special heat treatment that is required. Although the high-temperature properties are not specified, they are implied by control of chemistry, heat treatment, and room-temperature properties.DESIGN GUIDELINES FOR THE SELECTION AND USE OF heat treatment. In the annealed condition, all are essentially nonmagnetic, although some may become slightly magnetic by cold working. They have excellent corrosion resistance, unusually good formability, and increase in strength as a result of cold work. Type 304 (frequently referred to as 18-8 stainless) is the most widely used alloy of

Crystallization and Metal PropertiesWork-Hardening MetalHeat-Treating MetalSoakingAnnealingNormalizingQuenchingTemperingVariations in Heat TreatmentWhen molten metal cools, it freezes in crystalline structures. Under a microscope, these structures look like the frost crystals that form on glass in wintertime. Each structure grows from a center point until it meets with another crystal structure. These structures make up the grains of a metal. Just as varying winter conditions create lots of types of frost patterns, so variable temperatures change the crystals that make metal.
