Fitting Overlap Checking
Spec-Driven Piping automatically checks for the overlap of fittings when you insert fittings, automatic flanges and gaskets, redefine fittings, or replace fittings. For all such instances, Spec-Driven Piping:
Compares the length of the pipe segment between two adjacent fittings with the values specified for one of the following configuration options:
The pipeline_min_bolt_clearance configuration option if the pipe segment is between two flanged fittings or between a flanged and a nonflanged fitting
The pipeline_min_segment_length configuration option if the pipe segment is between two nonflanged fittings
If the length of the pipe segment is less than any of the values specified for these configuration options, then a message appears and the pipe segment that does not satisfy any of the above conditions is highlighted.
Checks for a fitting that overlaps another fitting at the given insertion location and tries to move the fitting to avoid the overlap. If the fitting cannot be moved, a message appears and the existing fitting that is being overlapped is highlighted. In such instances, no fittings are inserted.
For slip-on flanges and socket-welded fittings, Spec-Driven Piping does not automatically perform the overlap check for the fitting parts that lie outside the port. This is because the ports do not lie on the external surface of the fitting. To enable Spec-Driven Piping to perform checking for fitting overlap for slip-on flanges and socket welded fittings, use the OFFSET parameter to specify the additional distance between the port and the external surface and attach the parameter to the required port. Spec-Driven Piping performs the overlap checking for the additional distance from the fitting port location.
Spec-Driven Piping does not check overlap for no-break fittings during various piping modeling operations.
