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).

Applies to: Heating, Potable water, Waste water, Ventilation, Cooling, Gas.

Rigid pipes, Flexible pipes and Rectangular Ducts

Depending on the trade, 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

In the ventilation trade, the wall thickness of the duct material is displayed additionally for rectangular ducts.

Weight

In the ventilation trade, 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 potable water trade 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

In the ventilation trade, 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.
