10.7 Forwards and Backwards

When using the above examples the designer is required to work with the flow in “Forwards” Mode or against the Flow in “Backwards” Mode. This can be changed on the command line using the command

“FOR” or “BAC”.

It can however be selected using the Piping Components Form.

Select Create > Components

The Piping Components form should be used in conjunction with the Members form

Select Display > Members

www.aveva.com

When you use the Forwards and Backwards Radio Buttons the Members window is inverted

Select Forwards

In Forwards Mode the first component in this example is a flange.

Select Backwards

In Backwards mode the first component in this example is a Valve.

L

Make sure you always close the form in Forwards Mode

10.8 Alternative Positioning Example

Continuing from the elbow created in the previous exercise we are going to create two more elbows but this time we are going to position the elbows relative to the steelwork.

Set-up the design display to include pipe /100-C-13 and the pipe bridge steelwork /PIPEWAY

www.aveva.com

Create a New Elbow and position it 300mm after the column

Use Position > Component > Plane Clearance

Set the form as shown with a 300mm Clearance.

Select Apply and Identify Column /COL-B3

Your elbow should be positioned as shown.

Direct the Elbow leave to point up using Orientate Component > Leave.

www.aveva.com

Another elbow is created and positioned so that the bottom of pipe is resting on the steelwork.

Position > Component >BOP/TOP

Select Bottom of Pipe, Clearance 0, Behind, ID Cursor, Apply and Identify beam /AB4H

The Branch can be completed by specifying the tail as follows:

Bore 100

CHAPTER 11

11 Pipe Assemblies

Designers can use Pipe Assemblies that can be inserted into pipes both in the normal design process and during Pipe Splitting Operations. The creation of these Pipe Assemblies is covered in TM-1303 - Project Design Administration.

L

Pipe Assemblies are stored in Application Worlds and Areas.

11.1 Using Pipe Assemblies during Piping Design Navigate to and display /250-B-5

From The Pipework Toolbar Select Show pipe component form

On the component Creation Form Select - Assemblies

www.aveva.com

The Assemblies are selected using the Sub-Type Pull down and selecting the required assembly

Select Samples Assembly Area Select gate valve set

Place the assembly on the pipe /250-B-5

Select OK

Select WN and OK

Select OK

Select WN and OK

L

If a piping component can not automatically be selected via the selection type (STYPE) a warning message followed by a choose form is displayed to allow the Designer to pick the correct component.

The Flanges in spec /A3B do not have the same selection types (STYPE) as the spec that the assembly was built from so a message and a choose form would normally be displayed.

www.aveva.com

Exercise 14 - Using Pipe Assemblies during Piping Design

Using the above example place the Gate Valve Assembly into the pipe /250-B-5 the Flange assembly can be created in a similar way.

CHAPTER 12

12 Pipe Splitting

It is often necessary to split Pipes into more than one Branch or Pipe. Splitting Pipes is used to make the Isometric clearer or perhaps as a process requirement. Pipes can be split on components, on planes or into segments (or spools). Pipe assemblies are used to aid in the splitting of pipes.

12.1 Pipe Splitting at a component

Display Pipe /100-C-12 as shown

We will split the Pipe at Elbow 3 of Branch /100-C-12/B1

The Pipe Splitting form is displayed using Utilities >

Pipe Splitting

Select Split pipe by moving Component Select New Pipe

Select Split

Identify Elbow 3

The Pipe will be split into two pipes, the upstream branch will keep the same name whilst the downstream branch will be given a new name

/100-C-12-Split(1)

The bypass should be included in this pipe

www.aveva.com

Navigate to Pipe /100-C-12-Split(1) Select Modify > Hierarchy > Include

The form will be opened on Pipe /100-C-12-Split(1) Locate the Bypass Bran /100-C-12/B2

Select Include CE

The Bypass branch will now be included in the pipe /100-C-12-Split(1)

The Pipe and Branches should be renamed as required.

L

You should always run a Data Consistency Check if you edit a Pipe

12.2 Pipe Splitting on a Plane

To aid with the following example Pipes /100-C-13, /100-C-12 and the pipe Bridge Steel /PIPEWAY have been added to the screen.

In the following example we will split both pipes using a pair of flanges 1500mm from the southern most pipe bridge column.

The Pipe Splitting form is displayed using Utilities > Pipe Splitting

L

Note: The Split Pipe has been divided into sections for ease on explanation.

www.aveva.com

12.2.1 Elements to Split

There are 3 options for adding pipes to the Elements to Split which are self explanatory Add Pipe Branches

/100-C12-B2 and /100-C-13-B1.

12.2.2 Split Pipe Options, (Split Pipe on Plane)

There are various ways that the pipe split can be identified, in the example we will split the pipe on a plane.

Other split options are described later.

The pipe will be split on a plane that we will define later.

Select Split pipes on a plane

12.2.3 Moving Down Stream Components

There are three options following the pipe split: -

Existing - Will just insert Pipe Assembly into the existing Branch New Pipe - The pipe will be split into new pipes

New Branch - The pipe Branch will be split into extra branches.

Select Existing

12.2.4 Plane definition

The plane is used to describe the position of the split, set the following:

Pick any Pipe leg to place the cutting plane orthogonally Identify any of the pipes.

Pick to position the cutting plane Pick the South West Pipe Bridge Column (F-1)

www.aveva.com

The Cutting Plane should be drawn as shown

12.2.5 Assembly Selection

We will split the pipe using a pair of flanges

Select Sample assembly area Description FLAN GASK FLAN Assembly build origin Build to primary origin

12.2.6 Split Pipe

To Split the pipes select the Split Button

Select Yes

www.aveva.com

The pipes should be split as shown below.

12.3 Split Pipe into Segments

This option can be used if you wish to split the pipe in for example 2000 lengths.

Select Split pipes into segments Split By Component picks

Select a Segment Length of 2000

As before Select a Weld Neck Pipe Assembly Select the Split Button

You will now be prompted to select the start and end of the leg to be split.

Select Elbow 3 and Flange 2 of pipe branch /100-C13-B1

www.aveva.com

Exercise 17 - Pipe Splitting Using the above examples:

• Split Pipes /100-C-13, /100-C-12 on a plane

• Split Pipe /100-C-12 into segments Try splitting a Pipe into two pipes

CHAPTER 13

13 Pipe Editing (Component Bore/Specification)

The modify Pipe / Branch components form can be used to change the Pipe, Insulation and Tracing Specs and also resize the piping components. It can be accessed from either Modify > Pipe > Component bore / Specification or Modify > Branch > Component bore / Specification.

In the example we will change the Branch and Insulation Spec and resize some components.

Navigate to and display pipe /250-B-5

13.1 Changing Component Spec

Select Modify > Pipe > Component bore / Specification

Using the Right Hand Mouse Button on the display window displays the Modification Pull Down

Use the Right Hand Mouse and Select All

www.aveva.com

In this case we do not wish to change the pipe spec on the Flanges and Gaskets as they are connected to 300# Nozzles

Identify all Gaskets and Flanges using the L.H. Mouse Button with the <Ctrl> Key held down this will de-select the Flanges and Gaskets leaving the rest de-selected.

The Selection is also shown in the Graphics Window

Use the Right Hand Mouse and Select Modify Specification

www.aveva.com

The current Piping Spec will be displayed, Select Spec A1A using the pull down and OK

The right hand end of the form displays details of the component specification reference and description changes. These should be reviewed prior to using the Apply Button.

In our case there are no errors but typical errors are shown below.

Any errors should be reviewed using the Error Message Tab as you can see in the above example the Tee shows a comment “No selection available”

Select the Error Messages Tab

www.aveva.com

The spec that the Branch has been changed to does not contain a 250NB Butt Weld Tee, this will need to be resolved manually and could involve selecting a different component type.

Select Apply to make the changes

Exercise 18 - Pipe Editing (Component Bore/Specification)

Using the above example change the piping specification from /A3B-TRA to /A1A-TRA on the piping components, make sure that the Flanges and Gaskets are not changed. Run a Data Consistency check on the modified Pipe.

In a similar way change the insulation spec to W

The Branch Temperature will also need to be set to 150 Deg using Modify > Attributes at Branch and Pipe Level. In order to see the insulation you will need to show the insulation using Settings > Graphics Representation and setting the Insulation to 25%

www.aveva.com

13.2 Changing Component Nominal Bore

The modify Pipe / Branch components form can be used to resize the piping components. It can be accessed from either Modify > Pipe > Component bore / Specification or Modify > Branch >

Component bore / Specification.

In the example we will resize some components.

Navigate to and display pipe /250-B-5

Select the two elbows and the reducer using the Cursor

Select Modify > Branch > Component bore / Specification

Use the Select from graphics button to select the components for change.

Using the Right Hand Mouse button Select Modify Bore

www.aveva.com

Change the bore to 150mm and OK

L

You can see that there is no available reducer so it will not be changed Select Apply

www.aveva.com

As you can see from the above example the Elbows have changed size the connecting pipework should be changed manually.

Exercise 19 – Changing Component Nominal Bore

Using the above example investigate changing component Nominal Bore
