Buttons on the data sheet

 

Figure Nozzle list

The heat exchanger design module has three buttons. The first button is to edit the nozzles that are part of the exchangers. The heat exchanger design module creates a fixed amount of nozzles, in/out for the channel side and in/out for the shell side. When the button 'Nozzle List' is clicked the above window will be opened. Some nozzle data can be updated such as the type, rating, NomOD and the schedule. Other data can not be edited in the VES06A version. (This might change in the future versions)

Note: The nozzles indicated in the above nozzle list from the heat exchanger design module are an integral part of the heat exchanger design and will also be shown on the settingplan. Additional nozzles added to the heat exchanger will be used in the calculations but are not shown on the settingplan and are not part of the nozzle list in the design module.

The nozzle list can also be opened from the menu Edit > Nozzle List of the heat exchanger design module. When opening for the first time the created nozzles are indicated but empty with data.

  • The field 'mark' is used to indicated the nozzle on the drawing, this field can not be edited
  • 'Service' can be used to indicate the process service or medium
  • A button will be shown if the field in column 'Type' is clicked. Click this button to select the type of nozzle from the standard database, see below figure. With the selection of the nozzle the rating, NomOD and the detail data is set.

 

Figure Rated flanges selection

  • The 'Facing' is standard set to Raised Face (RF) and can not be edited at this point. The details of the gasket and facing can be changed later in the detail calculations of the nozzles
  • In the nozzle list, the 'Rating', 'NomOD' and 'OD' are set by selecting the flange. The values can be edited if required

Figure Pipe Schedule selection

  • 'Schedule' is used for the dimension of the pipe between the flange and the shell. A button is shown when selecting this field. Clicking this button will open the pipe schedule dialog. In this dialog the pipe nominal outside diameter and the schedule can be selected.
  • The 'Wall' and 'Tolerance' in the nozzle list are set by selecting the pipe for the nozzle. The values can be edited if required.
  • The nozzle list contains the fields 'WRing' and 'TRing' for the optional reinforcement ring. WRing is the width of the ring and TRing is the thickness of the ring. The VES program uses the width of the ring to determine the allowable distance to the nearest weld during design cycle of the equipment.
  • The 'StdOut' (stand-out), 'Orientation' and 'Neck orientation' are set by the program but can be set manually.

The nozzle list has now been set with the relevant information of the nozzles. The window with the nozzle list can now be closed. The next step is to complete the material list. Click the button 'Material list' to open the material selection dialog window.

Figure Materials of construction

The column with the 'Part description and Location' is completed by the heat exchanger design module. The columns Material, Td (design temperature), S(Td) (allowable stress by design temperature), S(20ºC) (allowable stress by 20ºC) and G (specific weight) are empty. Note: the Td needs to be set otherwise the following fields S(Td) and S(20ºC) can not be determined by the software.

The materials of construction dialog has another tab at the top for the extra material properties.

Figure Materials of construction – extra material properties

Click this tab to the modulus of elasticity for custom materials. Normally these values are present in the database for the standard database materials. The elasticity figures are used for the calculation of a fixed tubesheet of the heat exchanger.

After the materials have been set the dialog can be closed and the selected data is stored in the database. Now the main window will be again active of heat exchanger wizard data sheet. At the right top of the sheet click the button options.
