Creating single Pipe Penetration

The information about the hole size and position is held in a FIXIng which is held in a STRU with the purp of the STRU set to HOLE, on a project this design area would be created by the project administrator.

For the purposes of the training the fixing area will need to be created.

Select Utilities>Training Setup… from the main menu to display the Training Setup form.

Select the Upgrade tab, check the Create Association Worlds checkbox and click the Apply button.

This adds the Association Worlds (ASSOWL) and Association Group (ASSOGP) elements required for Equipment Associations and Hole Management.

In addition the Site SITE-ASSOC/ASSOC is renamed to VM-Virtual-Holes and the required Zone and Stru elements for Hole Management are added.

7.3 Creating single Pipe Penetration

There are three ways that the Pipe penetration can be selected, shown on the pipe branch and subsequent isometric.

 Pipe Attachment (ATTA) selected from the current piping specification.

This first method is very useful as the current piping spec does not need a special penetration attachment.

 Pipe Attachment (ATTA) selected from. a special Penetration Spec.

This method would allow the use of a different attachment representation on the Isometric.

 Pipe Coupling (COUP) selected from the current piping specification.

This method is very useful if penetration material is needed on the piping isometrics. Typical uses of this are penetration sleeves or water tight seals.

In this first example a single penetration where pipe 100-B-8 goes through the floor plate will be created with the piping attachment (ATTA) selected from the current piping spec.

Add Pipe /100-B-8 and Sub Frame

/EL(+)104880_TOS_PLATE to the screen.

Select

Utilities > Pipe Penetrations > Create Penetration From the main window pull down

Select Pick Penetrated Items

Identify the Panel

Select Pick Penetrating Items

Identify the Pipe /100/B-8

From the Specification pull down select From Pipe Spec

The bottom part of the form will change and a marker type pull down is displayed.

Select ATTA Select OK

A Specification Choose Form is displayed if there is more that one ATTA available.

Select FLOR TRUE Penetration ATTA Unset

Select OK

Set the form as shown



Class: Standard Types Type: Circular Hole – Type D

Initially the Diameter will be 115mm the OD of the Pipe. Setting the Clearance to 50 will automatically set the Hole shape parameters (Diameter in this case).

The Hole Shape selection area of the form contains Class options lists that enables the user to select the class of hole, i.e. Standard Types, Piping penetration piece tables and Pipe Duct. The Type options list changes depending on the Class selected. For this example Standard Types will be used.

The Type options list has the following entries.

The default is Circular Hole – Type D.



The Hole shape parameters area of the form displays different parameter textboxes for the different hole types. For a circular hole the only parameter is Diameter.

The Diameter value is defaulted to the Outside Diameter of the selected pipe, i.e. 115mm.



The Penetrating item clearance area of the form contains the Clearance textbox that enables a clearance around the penetrating item to be specified. Note that the Diameter value has increased from 115 to 215 i.e.

the pipe OD + 2 x the clearance.

The „virtual‟ hole clearance fixing is displayed at the specified clearance diameter.

Modify the required hole diameter by entering a number in the Diameter textbox and pressing the Return key. This increases the diameter of the

„virtual‟ hole such that it is greater than the specified clearance. This would be required for an eccentric hole.

The „virtual‟ hole fixing is displayed at the specified diameter (the outer of the two fixing extrusions shown).

The Set to Minimum button resets the hole shape parameters to the minimum value(s) required to create a valid hole. In this example clicking the button would set the Diameter back to 115.

The Positioning area of the form enables an offset in the X and Y directions for the penetration hole to be specified by entering appropriate values in the X Offset and Y Offset textboxes. This enables the penetrating item to be eccentric to the penetration hole, which may be required in some circumstances.

The Rotation gadget enables the hole shape be rotated to align the hole in a different direction. This is only relevant on non-circular hole shapes. The rotation value may be set by using the up or down arrow or by entering a value in the textbox.

The Single or Merged hole penetrations area at the top of the form enables individual single holes or a merged hole to be specified for multiple penetrating items by selecting the appropriate radio button. As there is only one penetrating item in this example the options are disabled.

Clicking the OK button on the Hole Management – Definition form creates the FRMW and two „virtual‟ hole FIXING elements, one for the clearance diameter and one for the penetration hole, in the STRU whose Purpose attribute is set to HOLE; STRU VH-Stru in the SITE HM-Virtual-Holes for this example.

The top level fixing is auto-numbered using the format HM-VH-nnnn, where nnnn is a four digit sequential number starting at 0001. The secondary level fixing is auto-numbered using the format HM-VH-nnnn-SUB-nn, where HM-VH-nnnn is the name of the top level fixing and nn is a two digit sequential number starting at 01.

The association is created in the ASSOGP whose Purpose attribute is set to HOLE and is automatically named using the format HM-ASSOC-nnnn, where nnnn is a four digit sequential number starting at 0001.



A fixing will have been created in the database ready for creating the hole using the Hole Management Application later.
