HEAT EXCHANGER & PRESSURE VESSEL DESIGN

img

Design of Thermal energy:

  • Process fluids are taken into account on both the shell and tube sides.
  • Choosing the Necessary Temperature Ranges,
  • Reducing the pressure drop on the shell and tube side,
  • Determining Velocity Limits for Shell and Tube Sides,
  • Using the proper correlations, get the heat exchanger’s overall heat transfer coefficient.
  • Determining the Fouling Factor and Heat Transfer Area.

Design of Mechanical Systems

  • TEMA Layout Selection: Based on Thermal Design
  • Tube parameter selection: material, pitch, thickness, size, and layout
  • Using Tube Length to Limit the Upper and Lower Designs
  • Material baffle cut, baffle spacing, and clearances are the parameters that are chosen for the shell side.
  • The substance of the tubes’ thermal conductivity.
  • Establishing upper and lower design limits for baffle cut, baffle spacing, and shell diameter.

The approximate overall design criteria serve as the basis for the material selection.

  • Part A of ASME Sec II: For Ferrous Materials
  • Part B of ASME Sec II: For Non-Ferrous Materials
  • ASME Sec II, Part C: For Filler Metals, Electrodes, and Welding Rods
  • ASME Sec II-Part D: For Material Properties

The mechanical design is finished based on the data and materials chosen.

For pressure vessels and U-stamp vessels, ASME Sec VIII Div 1 Boiler and power piping ASME Sec I. (S stamp vessels) For the repair and modification of pressure vessels (R stamp vessels), NBIC Parts 1, 2, and 3

  • Thickness of Shell
  • Thickness of Dish
  • Selection of Flanges in accordance with B 16.47 and B 16.50 (A and B Serious)
  • Pipe and nozzle selection in accordance with ASME B 36.10 M
  • Pipe and socket fittings in accordance with ASME B 16.11 M

The HTE Design Team will finish the design portion with a production drawing by adhering to the Quality Control Manual (QCM). following the Authorized Inspector’s approval of the design calculations and drawings.

The U stamping process will be used to begin production. If the buyer requests it, the vessel should be registered with the National Board. We will do so and add a “NB” stamp to the name plate along with the serial number of the vessel.
