Add Inline Components

Inline components, for example, valves or reducers, are added to the drawing canvas by dragging from the Symbol Palette, P&ID Explorer or directly from the grid.

The inline component can be rotated to the correct orientation and positioned directly on a centerline, secondary line or process instrument connection line. The pipe is split into separate centerlines and intelligent connection points are positioned at the arrive bore and leave bore which preserves the piping network system.

The example displays two centerlines and their references to the globe valve named GV01 on the centerline grid.

Attribute Propagation

By default, the following attribute values are propagated from the centerline that the inline component is added to:

• Arrive Bore

• Leave Bore

• Pipeline Fluid Specification

• Pipeline Insulation Specification

• Pipeline Specification

Additional attribute values can be defined to propagate from the centerline to the inline component using the attribute propagation settings in the Configuration module.

Note:
Specific attributes are available in the Configuration module to define the orientation and arrow head options for the placement of inline items on P&ID Drawings.

Note:
Specific attributes are available in the Configuration module to define the orientation, split point and arrow head options for the placement of reducers on P&ID Drawings.

Note:
Specific attributes are available in the Configuration module to define the orientation options for the placement of compound symbols on P&ID Drawings.

Flow Based Inline Items

Flow based inline items, defined with automatic orientation, are automatically positioned on the drawing canvas using the flow direction of the piping network segment. For example, a valve with automatic orientation is positioned using defined inlet and outlet connection points.

Bore Based Inline Items

Bore based inline items, defined with automatic orientation, are automatically positioned on the drawing canvas using the bore size of the piping network segment. For example, a reducer with automatic orientation is positioned using defined bigger and smaller arrive and leave connection points.

Arrow Heads

Inline items defined with arrow heads at the branch end are positioned with arrow heads on the appropriate centerlines to indicate the flow direction of the piping network segment.

Split Pipe

Inline items can be defined to split at pipe level which splits the piping network system and piping network segment when a reducer is added to the drawing canvas. The Create window displays.

Upstream

A piping network system and piping network segment are created upstream of the connection point of the reducer.

Downstream

A piping network system and piping network segment are created downstream of the connection point of the reducer.

Split Branch

Inline items can be defined to split at branch level which splits the piping network segment when a reducer is added to the drawing canvas. By default, a piping network segment is created downstream of the reducer.

No Split

Inline items can be defined to split at centerline level, which splits the centerline when a reducer is added to the drawing canvas. The piping network system and piping network segment are retained.

Refer to Symbol Palette, P&ID Explorer, Add Grid Records, Assign Component Specification, Attribute Propagation, P&ID Inline Item Attributes, P&ID Reducer Attributes and P&ID Compound Symbol Attributes for further information.
