Weld and Joint Connections

Connections between piping components (and tube) come in two forms: welds and non-welded joints (for example, flanged, screwed or compression connections). The welds and joints are grouped in the fabrication database in the Weld Group (WLDGRP) and Joint Group (JNTGRP) elements, respectively. These groups are created, by default, when numbering is first inserted into the Spool Drawing.

A connection is considered to belong to a Spool Drawing if:

• Both piping components involved in the connection belong to that Spool Drawing.

• The downstream piping component in the connection is on one end of the piping network in that Spool Drawing.

• In the case of a flanged joint with a gasket, the flange owning the gasket is on that Spool Drawing.
