Label Pipes with Breaks and Inline Breaks

Refer to Label Breaks and Inline Breaks.

Breaks can exist either at pipe boundaries or inline, within a pipe run. A Break signifies a change in specification, area, insulation, tracing etc from one pipe, or one segment of a pipe, to the next.

For breaks at pipe boundaries, there will be a different line number on each side of the break. An inline break is within a pipe, and therefore the pipe number is the same either side of the break.

A single break symbol can be labelled with multiple labels, signifying that the symbol represents more than one type of break, for example, where a trace break and an insulation break occur at the same point.

Label Breaks

Break symbols may be configured so that they are automatically labelled with pipe properties on insertion. For break symbols not configured in this way, labels must be placed "manually" by the user.

The procedure for labelling inline breaks and breaks at pipe boundaries is the same.

The upstream and downstream values of a break are initially populated with the upstream and downstream pipe properties.

As required, enter the upstream and downstream values of the break to reflect the change(s) in properties from one side of the break to the other. Only enter the values for those properties that are different. Values that are left blank will not label the break.

If the properties of a break are changed, the properties of the pipe are automatically changed as appropriate. For example, if the upstream area property of a break is changed, the area property of the pipe upstream from the break is also changed to reflect this. If there was a break upstream of the upstream pipe segment, its downstream area property would be automatically changed as well.

In the same way, changes made to the properties of a pipe segment are automatically applied to breaks at either end of that segment. For example, if the area of a pipe segment downstream of a break is changed, the downstream area property of that break is also changed to reflect this.

The project can be set up so that spec breaks result in a pipe being automatically split into two pipes if specific pipe properties are different on either side of the break.

Note: Deleting a break symbol will not result in the change in properties being removed. Breaks are indicators of such changes only (unlike reducers).
