Part Type: Welding Neck

Rules for the creation of individual 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 socket 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

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

Designation

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“

BESTELLVERMERK

Order note, individual content

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“

D_AUSSEN

Outer diameter, Connection“!“ and “2“

WANDDICKE

Wall thickness, Connection“!“ and “2“

ANSCHLUSSART

Connection type, Connection “!“ (always flange connection)

ANSCHLUSSART2

Connection type, Connection“2“

Possible values of the attribute ANSCHLUSSART (CONNECTION_TYPE):

1000x	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).
2000x	Flange connection
2100x	Flange with groove connection
2200x	Flange with notch connection
2010x	Flange connection of a loose flange.
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.

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.
