Label Nozzles

Nozzles are placed on vessels and on other items of equipment. When labelling a nozzle, a nozzle tag must be placed. If no nozzle size label is applied and a pipe is attached to the nozzle, the nozzle will inherit the pipe size on output. The nozzle may have a different size to the pipe and hence be an enlarging or reducing nozzle.

Duplicate nozzle labels are not permitted on a vessel. An error message is displayed if this is attempted. Duplicate nozzles are permitted on different vessels, for example, vessel V-100 and vessel V-200 may both have a nozzle labelled N1.

If warnings about nozzles which have labels missing are not required when performing an output, make sure that the Nozzle error balloon placement checkbox in the Label Types Configuration Category on the AVEVA P&ID Project Administration program is checked.

If nozzle sizes are to cascaded onto connecting pipes, check the Cascade Nozzle to Pipe checkbox in the Nozzles - Settings Sub-Category. To connect a nozzle to a pipe, so that sizes can be cascaded, refer to Connect Pipes to Nozzles and Equipment. To disconnect a nozzle from a pipe if cascading is not required for a particular pipe and nozzle, refer to Disconnect Pipes from Nozzles and Equipment.

If nozzles are to be labelled using an automatically incrementing number, check the Increment Nozzle Sequence checkbox in the Nozzles - Labels Sub-Category.

If nozzles labels are to automatically include a prefix, enter this prefix in the Nozzle Prefix field in the Nozzles - Labels Sub-Category.

Nozzles will automatically inherit the pipe specification and pipe specification description of a connected pipe branch when the drawing is consolidated after being committed or synchronized.
