Connection Types

The p-points of every piping component have associated connection types, derived from their catalog definitions. These are used in conjunction with the Connection Compatibility (COCO) tables, in the database, to check if two components may be legally connected to each other.

Note:
The connection type for the arrive and leave points of a TUBI component are always derived from p-point P1 of the tube catalog element.

The functionality has been extended for SPOOL so that it also specifies what type of connection it is. The type of connection is identified by the Ckey attribute, which is added to the COCO element definition. The Ckey attribute can be set to any of the standard Isodraft end connection types:

If the Ckey attribute is left unset, the connection is assumed to be ‘Plain’.
