Required attributes for entries into database or catalogue

The entering of attribute values and the part type selection should be performed using the PAA Editor.

Values need to be entered for at least the following attributes:

Attribute

Description

BENENNUNG

Designation of part

NORMBEZEICHNUNG

Standard designation of the part.

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

NENNWEITE

Nominal diameter, Connection "!" and “2“

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

NPS_INCH

Nominal diameter (inches) (e.g. 1 1/2‘', the '' consists of two '' characters), Connection “!“ and “2“

These parameters are to be considered for all connection types except for flange connections. For connecting sockets they refer to the pipe to be inserted:

D_AUSSEN

Outer diameter, Connection "!" and “2“

WANDDICKE

Wall thickness, Connection "!" and “2“

ANSCHLUSSART

Connection type , Connection "!"

ANSCHLUSSART2

Connection type, Connection “2“

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
2100x	Flange with groove connection
2200x	Flange with notch connection
2040x	Flange connection of a part that is not a flange itself. The part has a loose flange that is modelled as a sub-part and has no own article master attached to this connection.
3100x	Screwed, nipple
3200x	Screwed, socket
4100x	Plugged, nipple
4200x	Plugged, socket
5100x	Socket-welded, nipple
5200x	Socket-welded, socket

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.
