Variant for Part Type: Y-Piece (PE)

Rules for the creation of Feature Variants for Plant Engineering parts

Position of connecting points and determination of insertion lengths for various connection types
Connection for butt welding	Flange connection	Connecting nipple for screwed, plugged or socket-welded connection	Connecting sleeve for screwed, plugged or socket-welded connection

a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)	a = Insertion length dimension (e.g. L, L1 etc.)

Named isolated points

Designation	Purpose	Comment	Position in coordinate system
!	Connecting point	Fitting point	in origin (0,0,0)
2	Connecting point		X > 0, Y = 0, Z > 0
3	Connecting point		X < 0, Y = 0, Z > 0
4	Auxiliary point		X = 0, Y = 0, Z > 0

Variables names

Name	Description	Attribute (optional)
L1	Distance between point “!“ and “4“	LAENGE1
L2	Distance between point “2“ and “4“	LAENGE2
L3	Distance between point “3“ and “4“	LAENGE3

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.

A variables name may consist of a maximum of 4 characters and must not contain any spaces or special characters.

VAD file

Use the Variant Editor to expand the VAD file in such a way that it contains values for the parameters shown below, and that the preset attribute assignment is entered:

Parameter All dimensions must be specified in millimetres; Exception: Nominal diameters in inches	Variable (suggestion)	Assigned attribute
Nominal diameter, Connection “!“	N	NENNWEITE
Nominal diameter, Connection “2“ and “3“	N2	NENNWEITE2
Angle	W	WINKEL

Additionally (only if the corresponding standard uses nominal diameters in inches):
Nominal diameter (inches), Connection “!“	NI	N_INCH
Nominal diameter (inches), Connection “2“ and “3“	NI2	N2_INCH
As only decimal values are saved to the VAD file as parameter values, nominal diameters in inches need to be entered as decimal values as well (e.g. 1.5 for 1 1/2‘‘).

These parameters are to be considered for all connection types except for flange connections. For connecting sleeves they refer to the pipe to be inserted:
Outer diameter, Connection “!“	D	D_AUSSEN
Outer diameter, Connection “2“ und “3“	D2	D2_AUSSEN
Wall diameter, Connection “!“	S	WANDDICKE
Wall diameter, Connection “2“ and “3“	S2	WANDDICKE2

If required, the attributes LAENGE1, LAENGE2 and LAENGE3 need to be assigned to the length variables (see Variables names above).

Variant AutoSync

For variant auto-synchronisation, attribute values need to be entered that shall 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.

ANSCHLUSSART

Connection type for connection “!“

ANSCHLUSSART2

Connection type for connection “2“ and “3“

Possible values of the attribute ANSCHLUSSART (CONNECTION_TYPE):

1000x	Butt-welded	Provide auxiliary part when fitting part If appropriately preset in the ANSCHLUSSART (CONNECTION_TYPE) attribute for a connection, the part will provide and connect an auxiliary part of the standard specified in the attribute for the connection when being fitted. For example, if the part has a flange connection and the corresponding counter-flange is required, the content of the ANSCHLUSSART (CONNECTION_TYPE) attribute could look as follows: 20002 1 5100010 EN 1092-1/11/A/PN 40 EN 1092-1/11/A/PN 40 is the standard designation with which the flange is to be entered into the database.
2000x	Flange connection
3100x	Screwed, nipple
3200x	Screwed, sleeve
4100x	Plugged, nipple
4200x	Plugged, sleeve
5100x	Socket-welded, nipple
5200x	Socket-welded, sleeve

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.

When working with the HELiOS database, please pay attention to the correct classification!

Handling of nominal diameters in inches in the HELiOS database:

When performing a Variant AutoSync, the nominal diameters in inches are initially transferred to the attributes N_INCH and N2_INCH as decimal values. You can however use the HiCAD macro ANLDB_ZOLLATTRIGEN.MAC in the folder \HICAD\MAKROANL to subsequently generate the character sequences for value representation in inches (e.g. 1 1/2" instead of 1.5) in the database for the attributes NPS_INCH and NPS2_INCH.
