If the variables names given in the Name column are used, you do not need to assign any attributes to them via the Variant Editor. If different variables are required, you need to assign the attributes given in the Attribute column.

 

VAA file

Use the Variant Editor to enter the suitable part type into the VAA file.

Then, use the Variant Editor to expand the VAA file in such a way that it contains values for the sizes specified here, and that the predefined attribute assignment is entered:

Parameter

All dimensions must be specified in millimetres;
Exception: Nominal diameters in inches

Variable
(suggestion)

Assigned attribute


Nominal diameter, Connection “!“ and “2“

N

NENNWEITE

 

Additionally (only if the corresponding standard uses nominal diameters in inches):

Nominal diameter (inches), Connection “!“ and “2

NI

N_INCH

Nominal diameters in inches need to be entered as decimal values as well (e.g. 1.5 for 1 1/2‘‘).

 

For a connection socket, these sizes refer to the pipe to be plugged in:

Outer diameter, Connection “2“

D

D_AUSSEN

Wall thickness, Connection “2“

F1

WANDDICKE

If required, the attribute LAENGE (LENGTH) needs to be assigned to the length variables (see Variables names above).

 

For variant synchronisation, values must still be entered for the attributes that are to apply equally to all sub-types of the variant.

Values must be entered for at least the following attributes:

Attribute

Description

BENENNUNG

Designation of part

COMPONENT_TYPE

Part type (always = Semi-finished material + Plant Engineering) for HELiOS database only

NORMBEZEICHNUNG

Standard designation of the part (identical for all sub-types!)

An entry is mandatory, even if the part corresponds to no standard.

ANSCHLUSSART2

Connection type for Connection “2“

Possible values of the attribute ANSCHLUSSART (CONNECTION_TYPE)

Butt-welded

Provide auxiliary part when installing part

If a connection is specified in the attribute ANSCHLUSSART (CONNECTION TYPE), the part provides and connects an auxiliary part of the standard specified in the attribute when it is installed for the connection. Welding necks may provide loose flanges in their connection type. Since there is no part type Loose flange, it has been specified for welding necks that a loose flange is meant if the part type ID for flanges is used in the connection type, i.e. 5100010. For example, the content of the attribute ANSCHLUSSART (CONNECTION TYPE) could look like this:

20002 1 5100010 N2642 R2

Here N2642 R2 is the standard designation with which the loose flange was entered into the database.

 

In the connection type definition, a part type ID can also be used without additionally specifying the standard. So for welding necks you can define that you want to install a loose flange automatically, but you do not have to define the standard. If the loose flange is not unique, you will be offered a corresponding search mask (HELiOS or catalogue).

The last character (x) provides information about the meaning of the supplement:

0 =No supplement

2 = The supplement consists of connection number, part type, ID, and standard of the part to be connected

The prefixed connection number indicates the connection with which the auxiliary part is to be attached to the current connection.

 

Please also read the information given in the paragraphs Connection type ID with priority information and Connection type ID - List of part standards.

 

If welding necks are to be inserted with the loose flange from the connection attributes, the AutoFit connecting parts option must be activated on the Part selection tab of the Plant Engineering Settings dialogue window.

 

Handling of nominal diameters in inch in the HELiOS database:

During part data sync, the nominal diameters in inch are transferred as decimal numbers to the attributes N_INCH, N2_INCH and N3_INCH. The usual character strings for specifying the nominal diameters in inch (e.g. 1 1/2'' instead of 1.5) are automatically generated in the database for the attributes NPS_INCH, NPS2_INCH and NPS3_INCH..
