Details on Pipe Tables/Duct Tables
Information about the dialogs Pipe tables and Duct tables in the pipe or duct network calculation.
In these dialogs, neutral pipe or duct systems are offered under the manufacturer User-defined and the systems of the manufacturer you selected under Product data, or all installed manufacturers (for the disciplines heating and drinking water).
You are here:
Disciplines Heating, Cooling and Potable Water:
Disciplines waste water, gas and roof drainage:
Discipline Ventilation:
Applies to: Heating, Potable water, Waste water, Ventilation, Cooling, Gas.
Rigid pipes, Flexible pipes and Rectangular Ducts
Depending on the Discipline, different tabs and systems with corresponding tables are available.
Manufacturer
The manufacturer User-defined contains neutral systems that can be adjusted and expanded. The input is automatically saved in an external file.
If you selected a manufacturer in Product data, they will also be available here. In addition, in the disciplines heating and potable water, you can choose from all installed manufacturers and the associated pipe systems in the drop-down list Manufacturer.
System
Here you can select all systems that are contained in the selected manufacturer data set.
System tables
In the upper table, systems from the selected manufacturer are displayed. The systems under User-defined are expandable. To create a new system, click into a free row the system table.
| Element | Description |
|---|---|
| Active | Activate the field for the system you want to use for pipe and duct networks. Individual sections can be defined using the command Pipe material ... < in the calculation dialog box. Note: This column is not available in the disciplines heating and potable water. |
| Name | The name of the pipe or duct system is used for labeling and in the parts lists. |
| Abbreviation | The abbreviation of the pipe or duct system name is used for labeling. |
| Roughness | The rougness of the pipe material is used to calculate pressure losses. |
| Thickness | For the discipline ventilation, the wall thickness of the duct material is displayed additionally for rectangular ducts. |
| Weight | For the discipline ventilation, specific weight of the duct material is displayed additionally. |
| Color | The color is used by the Visualization command for displaying the pipe or duct system. |
Drag coefficient: (…)
In the discipline potable water each pipe system needs a material-dependent drag coefficient table assigned for the fittings. This assignment usually already exists. If the assignment is missing, select a suitable drag coefficient table for the respective material class.
Details
Shows or hides the lower dimension table.
Table of dimensions
In the lower table, available pipe dimensions of the selected pipe or duct system are shown. The dimensions under User-defined are expandable. To create a new dimension, click in an empty row of the table for Pipe dimensions. Dimensions are automatically sorted by size.
| Element | Description |
|---|---|
| Active | Only activated dimensions are considered during calculation. You can specifically exclude certain dimensions from automatic dimensioning by deactivating the field. The deactivated dimensions are still available for manual selection in the calculation dialog in the Section part section. |
| DN | Shows the available nominal diameters of the pipe. |
| Width, Height | For the discipline Ventilation, oval and rectangular ducts additionally show available widths and heights. Width and Height can be activated or deactivated separately for rectangular ducts. This is helpful if the height or width of a duct must be restricted. |
| d interior | Interior diameter is used for calculation and dimensioning. |
| d exterior | Exterior diameter is used for assignment of insulation from the insulation tables. |
| Indication of dimension | The dimension name can be selected freely and is used for labeling and in parts lists. |
| Valve size | Determines the connector size of built in valves. |
