Multi-Pipe Penetration with Sleeve

The Multi-pipe penetration with sleeve command allows constructing a common lead-through sleeve for pipes that penetrate the plate of a bulkhead or deck.

Inserting a multi-pipe penetration with sleeve

Perform the following to create a multi-pipe penetration with a common sleeve that strengthens the construction.

Prerequisites

Project administrator has defined settings for the common sleeve as described in Common sleeve settings. The settings determine the Nominal Size of pipes that pass through the common sleeve and also determine whether the common sleeve is constructed by using only plate material for the whole sleeve, or by using plate material for the straight segments and a (split) sleeve part for the curved sides.
Project administrator has defined hull plate material mappings as described in Hull plate material mappings. The mappings determine which catalog parts to use for the plate material and the sleeve part.
Pipes have been routed through a bulkhead or deck ('target plate').

Do the following:

In the Penetration group of the Piping tab, Select Insert > Multi-pipe penetration with sleeve.
In the object browser, select the common sleeve settings to use, and click OK.
In the 3D model, select the penetrating pipes, and press Enter.
Select the target plate, and press Enter.
You are prompted to specify plate side. This selection is not applicable in this context—you can select either Yes to accept the suggested side or No to select the other side, in both cases the construction will be symmetrical on both sides.
The Create Multi-Pipe Penetration tool opens showing information about the target plate, the penetration construction, and the penetrating pipes.

The tool uses outer diameter, length, and hole clearance values from the selected common sleeve settings, as determined by the penetrating pipe with the largest outer diameter. For example, if a common sleeve is constructed for pipes A and B, and pipe A's diameter is larger, the tool selects settings from that row of the common sleeve settings that matches pipe A's nominal size.

When the common sleeve is constructed using plate material and a sleeve part, the sleeve catalog part size is selected using hull material mappings and the common sleeve settings for the pipe (or flange) with the largest outer diameter. Hull plate material mappings define the sleeve catalog part based on target hull plate material. The sleeve catalog part size is the catalog part size belonging to the defined catalog part for which ODsleeve named dimension value matches the used settings row outer diameter value. From the selected catalog part size, the WTsleeve named dimension value defines the thickness of the arced parts of the common sleeve, ODsleeve defines the diameter of the arced parts, and Lsleeve defines the length of the common sleeve.

You can modify the penetration to be created, as described below.
Target plate properties displays the thickness of the target plate.

The tool selects the penetration material based on hull plate material mappings and target plate thickness. The thickness of the penetration plate material will be equal to or greater than the thickness of the target plate: if equal thickness is not found, the next greater thickness is selected. This applies to common sleeves made completely from the plate material as well as to the straight segments of common sleeves that use a sleeve part for the curved sides.
Define Penetration properties.
- Description shows the material selected for the penetration plate by hull plate material mappings.
- System defines the System to which the common sleeve will be assigned. Click Change if you want to change the assignment; the System you select will be the default the next time you use this tool.
Define Penetration parameters. Note that there is no Undo/Redo for the tools in this section.
- Shape selection is not available in this context.
  
  You can click Rotate to rotate the common sleeve on the target plate; this action recreates the common sleeve around the penetrating pipes and this can change its shape. You are prompted to first define a point on the width axis of the sleeve, and then the direction of the width axis.
- Overlap value is not displayed in this context.
  
  You can click Move to move the common sleeve on the target plate. You are prompted to first define a reference point and then the new location of the reference point. This action does not affect the shape of the sleeve.
Define Penetration group parameters.
- If Main pipeline is selected automatically is selected, the main pipeline of the penetration is selected from the penetrating pipe that has the biggest Nominal Size. Clear this option to select the main pipeline manually. (You can also change this setting later as described in Main pipeline of multi-pipe penetration.)
Intersecting parts lists the penetrating pipes. Selecting a pipe from the list highlights the pipe in the work views and enables additional options, if applicable.
- Use flange diameter is enabled and selected by default when the selected pipe has flanges. If selected, the size of the common sleeve is computed from the diameter of the flange. Clear this option to compute the size from the diameter of the pipe.
Click OK to create the penetration with the current settings.
