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, Connections “!“ and “2“ |
|||||||||
|
DICKE |
Seal thickness |
|||||||||
|
|
|
|||||||||
|
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), Connections “!“ and “2“ |
|||||||||
|
|
|
|||||||||
|
ANSCHLUSSART |
Connection types for Connections “!“ and “2“ (value = 20000 for flange connection) |
|||||||||
|
Possible values of the attribute ANSCHLUSSART (CONNECTION_TYPE):
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.

In previous versions the nominal pressure was of no significance for the search of matching sealing gaskets. To take pressures ranges into account, the attribute DRUCK_MIN (Minimum pressure) is now available.
When you now search a sealing gasket for a flange, the following, additional search condition will be generated from the nominal pressure PN of the flange:
(MIN_DRUCK ist unbelegt oder MIN_DRUCK <= PN) und (DRUCK ist unbelegt oder DRUCK >= PN)
(Minimum pressure not specified or Minimum pressure <=PN) and (Minimum pressure not specified or Minimum pressure >=PN)
Sealing gaskets without pressure specifications will thus be handled as if they were suitable for any nominal pressure.
The standard parts that are by default supplied with HiCAD do not include sealing gaskets with a defined pressure range. Therefore, this new feature is currently only relevant for gaskets that have been created by the user. Accordingly, the attribute DRUCK_MIN (Min. pressure) will not be available in the search masks that are by default supplied with HELiOS. If desired, you can add this attribute with the HELiOS Mask Editor.
If you prepare the database for Plant Engineering by clicking the corresponding button in DBPlantDataImport.exe, the attribute DRUCK_MIN will be entered, with the designation Minimum pressure, into the database.
An example from practice:
If you do not want gaskets with an own article number for each pressure level to be created, you can avoid this by means of the DRUCK_MIN attribute.
Furthermore, you have now the option to narrow search results for sealing gaskets by specifying a value for the attribute DRUCK (Pressure), e.g. by including only gaskets with a defined pressure in your pipe class.
