Multi-Pipe Penetration

A multi-pipe penetration consists of pipes that penetrate a target plate (usually, a bulkhead or a deck) using one common penetration plate. These pipes and the penetration plate are prefabricated as a single unit.

Note: If the hull plate is NOT from NAPA or CADMATIC Hull, the System of the target plate must have an additional attribute, "System for hole requests".

Requirements:

Sleeve(s) in library or project database. Using sleeve is optional.
Steel plate to be used as penetration plate.
Select the option Use hull plate material mappings in the shared project settings as described in Penetrations and create hull plate material mappings for the project as described in Hull plate material mappings. With these configurations, the penetration plate material and thickness is selected automatically for the multi-pipe penetration, according to the hull plate attribute and thickness.
System for target plate (bulkhead or deck) with additional attribute “System for hole requests”.
Penetration settings in the project database define the clearance distances. See Penetration settings.

Note: Object type for target plate must be Equipment.

Inserting a multi-pipe penetration with plate

Route pipes trough bulkhead or deck (target plate).
Start the Multi-pipe penetration command.
Select the penetration setting you want to use. At least one penetration settings must be defined for the project to be able to use the tool.
Select pipes to be assigned to multi-pipe penetration group. Press Enter after selection.
Click the target plate (the plate the selected pipes are penetrating).
An arrow shows the side of the target plate where the penetration plate is located. Click Yes to accept side or No to change the side.
The pipes are listed and the pipe parts which actually go through the penetration plate are listed in the Intersecting parts section.
Select the plate material for the penetration plate from catalog or if hull plate material mappings is set in project configuration and setting is on in options the plate is chosen automatically.

Note: It is recommended to select a plate of same thickness as the penetration plate.
Change the system for the penetration plate if needed.
Choose plate shape: Shape can be round, rounded rectangle, bicycle chain, oval or triangle depending on the amount and the position of the pipes. If pipes are not on the same level, then rotation can be used to obtain the desired penetration plate shape. Corner rounding for rounded rectangle and triangle shapes is given by the intersecting part with the greatest target hole radius.
Choose for each intersection part if dimensions for hole and plate overlap are taken from the flange. In case the toggle is not on the dimensions are taken from pipe or from sleeve. Measures come automatically for each nominal size from the selected penetration setting. If flanges are used they have to be added to the pipe before multi-pipe penetration tool is started.

Note: Hole Request is created automatically. However, the hole request is not deleted if the penetration plate is removed.

It is also possible to assign/de-assign pipe objects to/from multi-pipe penetration group in the Spool Tool, which is inside the Piping Isometrics tool. Note that this functionality does not change the penetration plate or hole request.

If it is needed to change the shape of penetration plate or hole request, the easiest way to do that is to delete the multi-pipe penetration group and create new one. Plate can be edited also with structural tab, plate group and section command.
