1 Introduction

1.1 About the DESIGN Reference Manual

The VANTAGE PDMS DESIGN Reference Manual describes all the DESIGN commands in detail. It also describes how the Design database is structured, the Design database elements and their attributes.

DESIGN is normally used interactively. The Graphical User Interface (GUI) provides discipline-based applications which help you to create, check and report on the model. How to use the applications is described in user guides and on-line help.

This manual is written for experienced users of PDMS DESIGN who need to use commands; for example, to write batch macros or to customise the GUI. If you are going to customise the GUI, you will also need to refer to the Plant Design Software Customisation Guide and Plant Design Software Customisation Reference Manual for information about PML, the AVEVA programming language.

1.2 Organisation of the DESIGN Reference Manual

The DESIGN Reference Manual has four parts:

• Part 1, General Commands, describes general DESIGN commands, which are used, for example, for setting up the display, and querying and navigating around the Design database.

In particular, it describes how to use the command syntax graphs, which are used to show all the options available for each command.

• Part 2, Creating the Model, describes the commands for creating database elements and setting their attributes.

• Part 3 (this volume) contains details of all the elements which can be created in the Design database, their position in the database hierarchy and their attributes.

• Part 4, Utilities, describes the DESIGN Utilities for data consistency checking and clash detection, and for exporting DESIGN data to programs such as REVIEW.

VANTAGE PDMS DESIGN Reference Manual 1-1 Part 3: Elements and Attributes Version 11.6

Introduction

1.3 Organisation of this Manual

Chapter 2, The DESIGN Database Hierarchy, shows all the Design database elements arranged as a hierarchy.

Chapter 3, Introduction to Attributes, describes the different types of attributes that Design database elements can have.

Chapter 4, Administrative and Reference Attributes, describes the Design elements which do not have any graphical representation (Sites, Zones, etc), and shows where they are described in the rest of the manual.

Chapters 5, 6 and 7 are the reference chapters for Equipment and Civils Elements, Structural Elements and Piping Elements respectively.

Note: For a comprehensive list of PDMS attributes and pseudo-attributes, see the Plant Design Software Customisation Reference Manual.

3 Introduction to Attributes

All the Design attributes can be queried and set by the user. However, many are automatically set as a result of DESIGN commands. Only the attributes that you would normally set explicitly are described in full. The ones that are set automatically are of interest because you can report on them.

Note that some attributes are used exclusively by PDMS modules other than DESIGN. These are not described here.

Attributes can be divided into two categories:

1. General attributes occur throughout the database; they are common to most elements. For example, OWNER (every element in the Design data has an owner), POS (position), ORI (orientation), BUILT (true or false, indicating whether it has been constructed on site or not).

2. Special Attributes belong to particular elements or classes of elements and have specific meanings for those elements; for example, FLOWD (flow direction) in a Branch.

The special attributes are either self-explanatory or are explained in the context of the element under which they appear in this chapter. The general attributes are best considered in terms of their effect on the Design Model, so their meanings and applications are described in the earlier chapters.

Note: Some special attributes are only used for drawing control within ISODRAFT or DRAFT. How the settings of these attributes are applied is described in the ISODRAFT or DRAFT Reference Manual. For a comprehensive list of all PDMS attributes and pseudo-attributes, see the Plant Design Software Customisation Reference Manual.

In addition to their standard attributes, elements may have one or more user-defined attributes (UDAs). These are set and used in the same way as standard attributes, except that the UDA names are distinguished by being prefixed with a colon (:) character. For further details, see the LEXICON Reference Manual.


Introduction to Attributes

3.1 Attribute Types

The following is a list of all the Design attribute types.

Name Attribute Every element except the WORLD can be given a name. All names start with a slash / and consist of any number of name parts separated by further slashes. The maximum length is 51 characters. A name part consists of any string of characters, letters, or digits, with the exception of $ or @. If the STAR command (qv) has been used, the * character has special significance.

The names given to elements are purely for your convenience and have no meaning in the system.

Examples: /HX42 /HX42/NOZ1 /16/23/NH4/H21/N4 /AREA3

Real Attribute A real attribute holds a single real number (e.g. 25.5, -0.057, 25683.5, etc.). Real attributes are generally used to store dimensions (e.g. DIAM, XLEN, etc.).

Integer Attribute An integer attribute holds a single integer or whole number (e.g. 1, -2, 4000, etc.). Integer attributes are used in Piping Components to identify connection points (ARRIV, LEAVE); in Equipment Primitives to identify obstruction levels for clash detection (OBSTR); etc.

Reference Attribute A reference attribute holds a reference to another element. The attribute holds the internal system reference number, e.g. =12/106, and not the name of the element. Reference attributes are used to forge logical links between elements. For example, the SPREF attribute is used to link a Piping Component element in the Design to a Specification Component in a Specification. Note that a reference attribute may be restricted to storing the references of particular types of element (e.g. the SPREF reference of a Piping Component may only contain the reference to a Specification Component element, i.e. an element of type SPCOM). The restrictions on individual reference attributes are shown in brackets with each attribute.

Logical Attribute A logical attribute is either TRUE or FALSE. An example of its use is the BUILT attribute in a Pipe which is needed to indicate whether the Pipe has been constructed on site or not.

Word Attribute A word attribute holds a string of up to four characters. Word attributes are used, for example, to indicate the direction of flow in a branch (FORW, BACK) etc.



Text Attribute A text attribute holds a string of up to 120 alphanumeric characters (e.g. ’HP STEAM’). This string must be input between closing single quotes or, optionally, between vertical bars (useful for entering imperial units, e.g. |4’6|).

Real Array Attribute A real array attribute holds more than one real number. For example, the position attribute (POS) consists of three real numbers and represents the X, Y and Z coordinates which define the position of an element.

Integer Array Attribute An integer array attribute holds more than one integer. For example, the LEVEL attribute consists of two integers and is used to control the level range of drawing detail.

Reference Array Attribute A reference array attribute holds more than one reference to another element. For example, a connection reference array (CRFA) is used to hold the connection links of a four-way valve (VFWA) or a CROSS.

Noclaim Attribute If an attribute is set to 'noclaim' it means that the attribute can be modified without having to claim the element. This reduces contention in specific area such as connecting branches to equipment where a number of piping engineers can connect their branches to the same equipment. Note that there would be no warning if two branches were connected to the same nozzle with the last user to do a savework “winning”.


4 Administrative and Reference Elements

There are a number of elements in the Design Model whose range of applicability is not confined to either Equipment, Piping or Civils. These include administrative elements (e.g. WORLD, SITE, ZONE), and elements which refer to restrictions and constraints set by the user (e.g. Penalty Volume, Routing Plane). The elements and their attributes and Members are explained in this section.


Administrative and Reference Elements

4.1 Administrative Elements

4.1.1 World Element (WORLD) Administrative Element

Description: The WORLD is the topmost level of the design hierarchy within which all other elements exist. It cannot be deleted or copied in the same way that applies to, say, a ZONE or a BOX. Its existence is controlled outside DESIGN by the ADMINISTRATION module of PDMS.

Attributes: Name /* Lock false

Legal Owners: None

Legal Members: SITE, GPWL, TPWL

4.1.2 Site Element (SITE) Administrative Element

Description: The SITE is one level below WORLD and is the most significant element that can be created, deleted, copied or moved. Each SITE may represent a geographical or administrative division of the plant.

Attributes: Name /name Lock false Owner /* Position E 0mm N 0mm U 0mm Orient Y is N and Z is U Function unset 120 character text Purpose unset 120 character text Number 0 Area 0 Module unset

Legal Owners: WORL

Legal Members: TEXT, ZONE, BOUN, DRAWI, GRDM, TMPL, DPSE, DDSE, PORS, LNKS



4.1.3 Zone Element (ZONE) Administrative Element

Description: The ZONE is the administrative element at the third level down the hierarchy. It may represent a geographical or administrative division of the plant and can directly own Equipment, Civils and Piping elements.

Attributes:

Name /name Lock false Owner /name Position E 0mm N 0mm U 0mm Orient Y is N and Z is U Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text Number 0 Area 0 Module unset Pspec Nulref Pipe Specification Ispec Nulref Insulation Specification Tspec Nulref Trace heating Specification DUnion 0 DRAFT union (common edge) setting

The following attribute is used for VPRM integration:

Fstatus unset Status string for VPRM integration

Legal Owners: SITE

Legal Members: TEXT, BOUN, EQUI, PIPE, STRU, PTRA, PVOL, DRAWI, RPLA, DATU, REST, HVAC, TMPL, DPSE, DDSE, PORS, LNKS

4.1.4 Group World Element (GPWL) Administrative Element

Description: This is a subsidiary World that contains only GROUPs and is owned by the main WORLD element.

Attributes: Name /name Lock false Owner /* Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

Legal Owners: WORL Legal Members: GROU



4.1.5 Group Element (GROUP) Administrative Element

Description: You may define as a GROUP any collection of elements in the database, assembling these elements as a single GROUP unit.

Attributes:

Name /name Lock false Owner /name Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

Legal Owners: GPWL

Legal Members: None (but it can have offspring of any element type)

4.1.6 General Text Element (TEXT) Administrative Element

Description: TEXT is a general element that can occupy most positions in the hierarchy. It can be used to store additional information about an owning or adjacent element.

Attributes:

Name /name Lock false Owner /name Stext unset Up to 120 characters of text

Legal Members: None

Legal Owners: SITE, ZONE, EQUI, STRU, PTRA, PIPE, BOUN, DRAWI, GRDM, SUBS, BRAN, REST, SUBE, FRMW, SBFR

4.1.7 Ground Model Element (GRDMODEL) Reference Element

Description: Basic shapes and features in the site can be represented by Ground Models. These may be natural occurrences like mounds or slopes. Each Ground Model element is built up in exactly the same way as a POHEDRON (polyhedron) which is described elsewhere. Restrictions on the form of Ground Models mean that they are of limited use. Complex surface profiles are better approximated by a ‘dummy’ STRUCTURE containing any of the basic shapes.



Attributes:

Name /name Lock false Owner /name Position E 0mm N 0mm U 0mm Orient Y is N and Z is U Level 0 10 Descript unset 120 character text Purpose unset 120 character text

Legal Owners: SITE

Legal Members: POGO, TEXT

4.1.8 Site Boundaries and Roadways Element (BOUNDARY) Reference Element

Description: For site layout features such as fences and roadways it will often be sufficient to restrict modelling to lines and arcs laid out on a surface. The BOUNDARY element allows this method of modelling by positioning member POINTS, IPOINTS (invisible points) and TANPOINTS (tangent points) to describe the required outlines. The BOUNDARY can be thought of as a ‘high level’ basic element (its identical low-level equivalent is the DRAWING, which can belong to EQUIPMENT, STRUCTURES etc.). The BOUNDARY has the normal drawing LEVEL attribute of a primitive, but no OBSTRUCTION (as it is composed entirely of lines).

5 Equipment and Civils Elements

This section describes the elements of the Design hierarchy that are available for modelling all non-piping (routed) items. The elements mentioned only take on a physical appearance from the primitive shapes that they own. The purpose of these elements is therefore to represent assemblies of primitives that provide convenient and manageable items of plant - structures, pumps, vessels, columns, stairways etc. In addition, they possess different Special Attributes that can hold information relevant to their function, construction status etc. This information can be reported on, in a chosen format, using the standard PDMS reporting utilities.


Equipment and Civils Elements

5.1 The Main Equipment and Civils Elements

5.1.1 Equipment Element (EQUIPMENT) Main Equipment/Civils Element

Description: The EQUIPMENT element represents process vessels, storage vessels, heat exchangers, pumps and any other predefined item that is part of the plant. The unique feature of this element is that it may own NOZZLEs in addition to the normal primitive shapes. Pipework can be connected to the Nozzles, thus making EQUIPMENTs intrinsic to the process system.

5.1.2 Process Subequipment Element (SUBEQUIPMENT) Main Equipment/Civils Element

Description: The SUBEQUIPMENT element is similar to the EQUIPMENT element, except that it is owned by an EQUIPMENT element and cannot itself own SUBEQUIPMENT elements.

5.1.3 Structure Element (STRUCTURE) Main Equipment/Civils Element

Description: The structural framework of the plant (for example, buildings, pipe racks, equipment racks) can be modelled on a simple level using the same basic set of primitive shapes available for Equipment (the main difference being that such elements cannot own Nozzles).

The principal feature of the STRUCTURE element is its ability to own SUBSTRUCTURES as well as primitive shapes, Routing Planes and Penalty Volumes. This enables, say, a rack to be further divided into beams and columns. (See also Section 6.1 for the use of this element in designing Steelwork Structures.)

Attributes: Name /name Lock false Owner /name Position E 0mm N 0mm U 0mm Orient Y is N and Z is U Built false Skey unset A code which indicates the symbol and annotating text which will be shown when the element is used as a reference datum for ISODRAFT dimensions.

5.1.4 Pipe Track Element (PTRACK) Main Equipment/Civils Element

Description: The Pipe Track is a type of STRUCTURE along which pipes are to be routed. It is a special element for the automatic pipe routing function of DESIGN; it cannot own SUBSTRUCTURES.

5.1.5 Substructure Element (SUBSTRUCTURE) Main Equipment/Civils Element

Description: Minor structural elements such as beams, columns, walls, ladders and staircases can be modelled with the standard set of basic primitive shapes within a SUBSTRUCTURE element.

5.2 The Primitive Modelling Elements

This section describes the elements that give the Equipment and Civils items a real physical shape. They comprise standard solid shapes and a special Component of EQUIPMENT items - the NOZZLE. These elements can all be positioned and oriented within their owning item; in order to facilitate this, they possess standard positioning points (p-points) which also allow connection operations.

This comprehensive set of geometric shapes forms the physical information from which non-piping items are constructed. Each shape has a set of special attributes that give it a physical appearance, e.g. CYLINDER has attributes DIAMETER and HEIGHT. All the primitives contain the attributes LEVEL and OBSTRUCTION which allow them to be selectively drawn in DESIGN or DRAFT, or clash checked in DESIGN. (DRAWI does not have an OBSTRUCTION as it can only contain lines).

5.2.1 Nozzle Element (NOZZ) Primitive Element

Description: NOZZles are significant to the Design because they provide the link between an EQUIPMENT (which owns them) and a Pipe (BRANCH) which is connected to each one.

Attributes:

5.2.12 Solid of Revolution (REVO) Primitive Element

Description: The Solid of Revolution represents any shape which can be generated by sweeping a constant cross-section profile through an angle about an axis. The profile is represented by a LOOP, in the same way as for an Extrusion, but in this case the profile is swept about an axis rather than along a linear path. The swept angle must be in the range -360 to +360 degrees, 360 degrees giving a solid which is axially symmetrical.

5.2.17 Solid Polyhedron Element (POLYHE) Primitive Element

Description: This versatile element represents a 3D polyhedral volume in terms of sets of points which define the vertices, and hence the edges, of the planar faces (POLFACs) enclosing the volume.

Each POLFAC is defined by one or more planar Polyhedron Loops (POLOOP). Each POLOOP is defined by a sequence of vertex positions which are identified by means of a Loop Points element (LOOPTS). The LOOPTS comprises references to sets of Point (POIN) elements held by administrative Polyhedron Point List (POLPTL) elements. Any POIN which lies on a common edge between two faces will be referenced more than once (one reference from the LOOPTS of each POLOOP which shares that POIN).

5.2.18 Polyhedron Point List Element (POLPTL) Primitive Element

Description: An administrative element which holds Point (POIN) members defining the vertices of a Solid Polyhedron (POLYHE) or Negative Polyhedron (NPOLYH).

Attributes:


Legal Owners: POLYHE, NPOLYH

Legal Members: POIN

5.2.19 Polyhedron Face Element (POLFAC) Primitive Element

Description: An administrative element which holds Polyhedron Loop (POLOOP) members representing the faces of a Solid Polyhedron (POLYHE) or Negative Polyhedron (NPOLYH). For an unbroken face, each POLFAC will normally hold one POLOOP only, but a discontinuous face may be represented by a POLFAC comprising two or more POLOOPs.

Attributes:

Name /name Lock false Owner /name Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

Legal Owners: POLYHE, NPOLYH

Legal Members: POLOOP

Note: Polyhedron Faces (POLFACs), unlike Polygons (POGOs), are not represented in the spatial map used for clash checking etc.



5.2.20 Polyhedron Loop Element (POLOOP) Primitive Element

Description: The POLOOP represents a planar profile which defines all or part of the shape of a Polyhedron Face (POLFAC). It is defined by a set of edges linking adjacent Point (POIN) elements, the latter being identified by references held in a Loop Points element (LOOPTS) owned by the POLOOP.

The order of the vertices (i.e. whether they are sequenced clockwise or anticlockwise) is significant. The order for a loop representing a positive polyhedron face is the opposite to that representing a negative polyhedron face. The LMIRR attribute determines whether the face points are read from start to end of the list, or in reverse. Reversing the order changes the loop from a positive outer boundary to a negative hole boundary, or vice versa. By default, points listed anticlockwise correspond to a positive boundary.

Attributes:

Name /name Lock false Owner /name Lmirr false Reverse vertex order (clockwise/anticlockwise) Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

Legal Owners: POLFAC

Legal Members: LOOPTS

Note: The directions clockwise and anticlockwise refer to the sense when looking from the outside of the face into the polyhedron.



5.2.21 Loop Points Element (LOOPTS) Primitive Element

Description: A LOOPTS element holds a set of pointers to the individual Point (POIN) elements which define each vertex of a Polyhedron Loop (POLOOP). These pointers are stored in the VXREFS attribute of the LOOPTS. The POINs referenced are themselves stored under a Polygon Point List (POLPTL) element.

The points referenced by VXREFS must be stored under a POLPTL under the relevant POLYHE or NPOLYH. To preserve the integrity of the primitive, points stored elsewhere will not be considered.

A POLOOP can hold multiple LOOPTS elements, each LOOPTS being limited to a maximum of 500 POINs. The order of points round a loop is in member list order of each LOOPTS in turn.

The INVIS logical array determines the visibility of edges. The points referenced by this array correspond to those referenced by the VXREFS array. If the INVIS pointer is set to False for any point (or, by default, is unset), the edge between that point and the preceding point will be visible; if set to True, the edge will be invisible.

Attributes:

Name /name Lock false Owner /name VXREFS unset Vertex cross-reference array (500) Invis unset Vertex invisibility array (logical, 500)

Legal Owners: POLOOP

Note: A POIN referenced from a LOOPTS with the INVIS flag set to True behaves like an IPOIN in a POGO (see page 5-22).



5.2.22 Drawn Line Element (DRAWI) Primitive Element

Description: DRAWI is an element which may be used to produce a symbol or shape on a drawing not normally catered for elsewhere in PDMS. If, for example, it were necessary to show a company name in large letters painted on the side of a tank, the letters could be built up as DRAWI elements which would be members of the EQUIP containing the tank. Commonly used to show the centreline of a beam or column.

5.3 Holes in Primitive Elements

Holes of any shape can be created in a primitive by creating a ‘negative’ primitive owned by the ‘positive’ primitive within which the hole is to appear. Any type of positive primitive may own any type of negative primitive. The negative shapes have position, orientation and dimensions which govern how they penetrate their owner. Holes can pass either partially or completely through their owners, but special rules should be observed when penetrating the surface of a primitive.

6 The Structural Elements

This section describes those elements which allow you to design logically interconnected steelwork or concrete structures. The elements have been subdivided into two types: those representing administrative classifications or tangible components used during the design of the structure; and those used solely for stress analysis purposes on the assembled interconnected structure.

This section describes those elements of the Design hierarchy that allow Piping to be modelled. These include all routed items - pipes, ducting, cable trays and hangers. The elements described here obtain most of their physical appearance from the PDMS Catalogue, although unique attributes such as position are held in the Design hierarchy. The basic Components of a route are organised into a sequence which represents its Head-to-Tail logic. It is therefore important with these elements to control their location within the hierarchy carefully (as achieved by the routing commands).


The Piping Elements

7.1 The Main Piping Elements

7.1.1 Pipe Element (PIPE) Main Piping Element

Description: The PIPE is an administrative owner of one or more two-ended BRANCHes. Usually a PIPE will include a principle BRANCH routed between two NOZZLES, with subsidiary BRANCHes for control loops, bypasses to spare pumps etc. The PIPE contains functional attributes of three types:

• Those which are used directly from the PIPE element (by modules such as ISODRAFT) as a collective attribute for all the BRANCHes in the PIPE, e.g. Pipe Spec (PSPE).

• Those which have no direct significance at PIPE level, but which are cascaded downwards to member BRANCHes (or even Components) where they perform a particular function, e.g. TEMPERATURE - only used by Branch for insulation, stressing etc.

• Information attributes that can only be reported on, e.g. BUILT. Attributes:

Name /name Lock false Owner /name Built false Shop false Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

The following attributes have functional significance at PIPE level:

Temp -100000 Temperature rating. Used by the detailing interfaces. Pspec Nulref Pipe Specification. Used by modules such as ISODRAFT, which places it in the title block of the isometric. Ispec Nulref Insulation Specification. Used by ISODRAFT. Tspec Nulref Trace heating Specification. Used by ISODRAFT. Ptspec unset Paint Specification. Used in ISODRAFT.

Revision -1 Revision. Used by ISODRAFT, which automatically increments value and places it in isometric title

block.

The following attributes only have a functional significance below PIPE level and are cascaded from the PIPE setting:

Lntp 0 Line Type Identification Erection 0 Erection Class Pressure 0 Pressure rating Matref Nulref Material Reference Fluref Nulref Fluid Reference Casref Nulref Case Reference

The following attributes are used to store information:

Dscode unset Design Code (text) Insched unset Inspection Schedule (text) Duty unset Fluid flowing through pipe (text) Ccentre 0 Cost Centre Cclass 0 Cost Class Safclass 0 Safety Class Bore 0mm Nominal Bore (no physical significance) Skey unset A code which indicates the symbol and annotating text which is to be shown when the element is used as a reference datum for ISODRAFT dimensions.

The following attributes are used by the Spooling application only:

Lissue false Status flag showing if drawing has been issued or not. Wmax 0 Maximum Weld Number used. Pmax 0 Maximum Part Number used. Smax 0 Maximum Spool Number used. Jmax 0 Maximum Joint Number used. Drrf Nulref Drawing reference. Cdrg unset Cnumber unset Carea unset Splp unset Spool prefix text.

7.1.2 Branch Element (BRANCH) Main Piping Element

Description: The BRANCH is the key element for all routed piping in the Design model. It represents a two-ended entity whose route is defined by its Head, Tail and the sequence of Components (Members) between. A BRANCH Head or Tail may be connected to NOZZLEs, multi-way Components such as TEEs, or other BRANCH Heads or Tails. Alternatively, a Head or Tail may be positioned explicitly in space. (All the commands which control the Head and Tail attributes are described in Chapter 11.) The remaining BRANCH attributes are for:

• Functional use

• Information storage

Attributes:

Name /name Lock false Owner /name Built false Shop false Shop fabricated flag. Cascades to Component level to indicate shop or site fabrication for ISODRAFT. Descript unset 120 character text Function unset 120 character text Purpose unset 120 character text

The functional attributes of BRANCH are as follows:

Detail false Can be set automatically by ISODRAFT to indicate that Branch has been detailed. Lstressed false Logical Stressed. Can be set by stress analysis programs to show that Branch has been stressed. Flowd unset Flow Direction. Used by ISODRAFT. Hstube Nulref Head Specification Tube. Describes Tube from Branch Head to first Component. Pspec Nulref Pipe Specification. Used by Selection process to search automatically for correct specification for Branch and its Components. Ispec Nulref Insulation Specification. Cascades to Component level to indicate insulation requirements for each Component. Temp -100000 Temperature. Used to determine insulation thickness for each insulated Component of the Branch, or for stress analysis. Lntp unset Line Type Identifier. Used by ISODRAFT to indicate if Branch is jacketed. Erection 0 Erection Class. Indicates wastage grouping for

ISODRAFT. Pressure 0 Branch internal pressure rating. Used for stress analysis. Matref Nulref Material Reference (SOLID). Used for stress analysis, to override material specification for Branch. Fluref Nulref Fluid Reference (FLUID). Used for stress analysis, to override fluid specification for Branch. Casref Nulref Case Reference (GROUP). Indicates current stressing case for stress analysis programs. Tspec Nulref Trace heating Specification. Overrides PIPE tracing for ISODRAFT (text). Ptspec unset Paint Specification. Overrides PIPE paint specification for ISODRAFT (text). Splh unset Holds spool number for Branch Head Tube, for use by ISODRAFT’s Repeatability function. Hdmtype unset Head dimension type is a 2-fold word array used to set dimension format for ISODRAFT reference dimensioning. Hdmfarray unset Head dimension array is a 2-fold reference array used to set names of reference elements for ISODRAFT reference dimensioning. Tdmtype unset Tail dimension type is a 2-fold word array used to set dimension format for ISODRAFT reference dimensioning. Tdmfarray unset Tail dimension array is a 2-fold reference array used to set names of reference elements for ISODRAFT reference dimensioning.

The Information attributes of BRANCH are as follows:

Dscode unset Design Code (text). Insched unset Inspection Schedule (text). Duty unset The fluid flowing through the pipe (text). Ccentre 0 Cost Centre. Cclass 0 Cost Class. Safclass 0 Safety Class.

Weight/Centre of gravity pseudo-attributes:

BRWEIG unset Weight of the Branch BRIWEI unset Weight of the Branch with insulation BRWWEI unset Wet Weight of the Branch BRWIWE unset Wet Weight of the Branch with insulation BRCOG unset Centre of gravity of the Branch BRICOG unset Centre of gravity of the Branch with insulation BRWCOG unset Wet Centre of gravity of the Branch BRWICO unset Wet Centre of gravity of the Branch with

insulation


The Piping Elements

The following data will have to be set up before the above attributes will work:

• The SPCO of every Component, bar ATTAs, will have to have a set CMPR pointing to a CMPD element or TUBD element in the property database. TUBD is best used with Bends and Components where the exact weight is not known.

• The SPCO of all the implied tube will also have a set CMPR pointing to a TUBR

• The CMPD elements will need to have CWEI set with CIWE if insulation is needed. If wet values are required then the ACBO is used if set, otherwise the leave bore of the Component is used.

• For TUBD elements UWEI and UIWE are needed with, optionally, ACBO

• If wet properties are required then the FLUR attribute of the BRAN and PIPE will have to be set pointing to a FLUI element in the property database. This will own a TDEN and it in term a SDEN with a set DENS attribute.

• If the CIWE and UIWE values are unset, the insulated weight can also be calculated from an approximate volume times its density. The shape of the insulation is assumed to be a hollow cylinder and the density is derived from the MATR of the insulation SPEC.

The following are known limitations of this implementation. Some of these may be addressed in future releases depending on the desired accuracy.

• The COG of the branch members is assumed to be that of the origin.

• The density of the fluid is a constant.

• The internal volume is approximate. It is assumed to be a cylinder for every Component.

• Bolts are ignored; their weights will have to be included in specific Component weights.

• These attributes only work for PIPE, BRAN and BRAN members. A grand total weight for, say, Pipes and Structures will have to be done by hand.

• Also works for SPLDRG, SPOOL and FIELD elements.

The Piping Elements

7.1.3 Branch Head and Tail Main Piping Element

Keywords: HREF TREF HPOS TPOS HDIR TDIR HCON TCON HSTUBE HSROD

Description: When a BRANCH (or HANGER) is created, a Head and Tail are immediately available to represent the two ends of that item. The Head and Tail are special because they are not separate Design elements but rather attributes of the BRANCH (or HANGER). This is because they are always required, being the minimum information necessary to describe a two-ended entity.

If the Head and Tail are set up with no intermediate Components, the content of the Branch will be one piece of straight Tube (or Rod) running between them. When the BRANCH (or HANGER) is created, the Head and Tail have no position, orientation, bore or connection type. These can be set collectively by connecting to another BRANCH or a NOZZLE, or individually if positioning the BRANCH in free space. They can also be referred to collectively as the PH and PT (or HH and HT) respectively. The Head and Tail attributes of BRANCH (and HANGER) are as follows:

Href,Tref The name of the element to which the Head or Tail is connected (e.g. a Nozzle, a Tee in another Branch, or another Branch Tail).

Hpos,Tpos The Head or Tail position in Zone axes (PIPE has no POS attribute).

Hdir,Tdir The Head or Tail position in Zone axes (PIPE has no ORI attribute).

Hcon,Tcon The connection type of the item to which the Head is connected (e.g. the flanged face of a Nozzle).

7.1.4 Restraint Element (RESTRAINT) Main Piping Element

Description: The area of the hierarchy owned by the RESTRAINT element is provided to allow modelling of pipe supports and hangers. The RESTRAINT is an administrative element which can own HANGER elements in convenient groupings. It is analogous to the PIPE element.

Attributes:

7.1.5 Pipe Hanger Element (HANGER) Main Piping Element

Description: The HANGER is a two-ended entity which is routed between a BRANCH and supporting steelwork. It is analogous in many respects to the BRANCH element and can own Components routed between a Head and Tail. The Head or Tail can be connected to a piping attachment point (ATTA) or positioned specifically, e.g. on a supporting member. Its attributes can be classified as follows:

• Functional and Information attributes for the complete HANGER (described here).

• Head and Tail attributes (already described).

7.3 Piping Components

7.3.1 Attachment Point Element (ATTA) Piping Component

Description: The ATTACHMENT point has three main applications:

• To allow pipe HANGERS to be connected to a point in the BRANCH

• To indicate a special point on the BRANCH which can be dimensioned, labelled, etc.

• To allow forces, moments, etc. to be applied to the BRANCH during pipe stressing.

The ATTA is created, selected and consistency-checked in the same way as other Components. However, it is ignored as an in-line fitting by the CONNECT command and is ignored by the reporting utility when listing tube lengths.
