Piping and Instrumentation Diagram (P&ID) Standard

Unique Identifier: Revision: Page:

240-61227631 1 4 of 69

Introduction P&IDs show the engineering details of process plant equipment, process flow details, instruments, process control loops, piping, valves and fittings; their location and their arrangement. This Standard provides criteria for the development of Piping and Instrumentation Diagrams (P&IDs) as well as the criteria to assist with the set-up and use of the key items on the P&ID symbol library.

1 Supporting clauses 1.1

Scope

This P&ID Standard is primarily based on the international standard, ISO 10628: Flow diagrams for process plants – general rules, as well as from the symbols and procedures applied in previous Eskom Group Technology projects. However, the industry has no generally accepted standards for the type and amount of information contained in a P&ID. This standard therefore defines Eskom’s requirements for P&IDs, including the development process, detailed requirements and applicable examples. This standard addresses the format and content shown on a P&ID. The information requirement is independent of the maturity of the P&ID or the phase in its life cycle, and therefore includes application in the design, construction, operational and maintenance phases. Note that this standard applies directly to utility flow diagrams (UFDs) but not to process flow diagrams (PFDs), block diagrams (BDs) or process flow schematics (PFSs). These three types are covered by the Process Flow Diagram Standard, 240-54690969.

1.2

Purpose

The purpose of this Standard is to provide detailed criteria for designers to prepare P&IDs. P&IDs form the specification basis for the instrumentation requirements of a project or in support of plant modifications. It is also the basis for developing all control loops and control logics of a plant.

1.3

Applicability

This document shall apply throughout Eskom’s Divisions. The intended users of this Standard include both Eskom technical personnel as well as contractors. Where contractors cannot provide P&IDs in accordance with this standard, provision needs to be made for redrafting the P&IDs to meet this standard. This standard is applicable during the design phase as well as the operational phase, e.g. modifications. 1.3.1

Applicability during the Design Phase

The development of P&IDs is a key step in the design process since it forms the basis for a range of other design elements. The following are design outflows from the P&IDs: 

specification of process equipment;



specification of pipes, fittings and valves;



specification of operational technologies;

1.3.2

Applicability during the Operational Phase

Unique Identifier: Revision: Page:

240-61227631 1 5 of 69

During the Operational Phase, plant operability is reviewed in order to improve plant efficiencies, process control and safety. P&IDs need to be fully reviewed in preparation for any modifications or changes to the control systems or control logics. The management of FDs after the design phase is controlled through the Engineering Change Management System.

Definitions

For the purposes of this Standard, the following definitions apply: 1.5.1

Auxiliaries

See “Utilities” in Paragraph 1.5.22 1.5.2

Block diagram (BD)

A BD is a form of PFD where individual equipment symbols are not shown but rather complete processes (systems or sub-systems) and these are simply represented by rectangular blocks. 1.5.3

Business process

A set of defined ad-hoc or sequenced collaborative activities performed in a repeatable fashion by an organization. Processes are triggered by events and may have multiple possible outcomes. A successful outcome of a process will deliver value to one or more stakeholders.

Component

A system element comprised of multiple parts; a cleanly identified item. 1.5.5

Design baseline

A design that has been formally reviewed and agreed upon, that thereafter serves as the basis for use and further development, and that can be changed only by using an approved change control process. 1.5.6

Design basis

Design basis consists of the design inputs, the design constraints, and the design analysis and calculations. It includes topical areas such as seismic qualification, fire protection, and safe shutdown. The design basis encompasses consideration of such factors as facility availability, facility efficiency, costs, and maintainability, and that subset that relates to safety and the authorization basis. The design basis explains why a design requirement has been specified in a particular manner or as a particular value. 1.5.7

Equipment

Generic term used to describe physical hardware and associated firmware / software that may constitute a system or subsystem or component. 1.5.8

Flow schematics

Flow schematics are derived from FDs with the difference that each FD element is represented by a schematic that approximates the physical configuration of the actual equipment rather than a general symbol. 1.5.9

Interface

An interface is a shared boundary between two functional units, defined by functional characteristics, common physical interconnection characteristics, signal characteristics, or other characteristics, as appropriate. 1.5.10 Off page connector Streams on FDs may link to the same system on other drawings or with interfacing systems. Off page connectors indicate how the drawings are connected to other drawings. 1.5.11 Piping and Instrumentation Diagram (P&ID) The piping and instrument diagram (P&ID) is based on the process flow diagram and represents the technical realisation of a process by means of graphical symbols for equipment and piping together with process measurement and control elements.

1.5.12 Plant process A plant process is a particular, specific sequence of steps to change the raw materials, intermediates, or sub-assemblies into the finished product or outcome. These process steps may involve conversion of an existing process stream into a new sequence of steps to meet facility requirements. Proven sequences of steps involve the least risk, while experimental processes have a potential for change or problems. 1.5.13 Process Flow Diagram (PFD) The PFD represents a process or a process plant with the aid of graphical symbols interconnected by flow lines. The graphical symbols represent equipment and the lines represent mass and energy flows or energy carriers. 1.5.14 Process parameter A process parameter is one of a set of numerical or other measurable factors that defines a plant process or sets the conditions of its operation. A process parameter can also indicate a quantity whose value is selected for a particular circumstance and in relation to which other variable quantities may be expressed. 1.5.15 Redundant equipment Redundant equipment exists when two elements within a system performs an identical function at different times. A component which is not functional in conjunction with other similar equipment or component is considered as “Spare” or on “Stand-by” mode. 1.5.16 Service A service is the performance of activities such as design, fabrication, inspection, non-destructive examination, repair, or installation. 1.5.17 Services See “utilities” in paragraph 1.5.22. “Services” should not be confused with “service” as defined in paragraph 1.5.16. 1.5.18 Subsystem A subsystem is an integrated set of assemblies, components, and parts which performs a cleanly and clearly separated function, involving similar technical skills, or a separate supplier.

1.5.19 System A set or arrangement of elements [people, products (hardware and software) and processes (facilities, equipment, material, and procedures)] that are related, and whose behaviour satisfies operational needs and provides for the life cycle sustainment of the products 1.5.20 System physical boundary The physical boundary of a system is defined by the equipment and components bearing the same KKS / AKZ designation within the system. 1.5.21 Tag For the purposes of labelling instrumentation and control components, a hardware device or a software point is identified with a systematic tag number. 1.5.22 Utilities The term “utilities” includes electricity, water, fuel, air, and steam used in the production of a product. Utilities are in some cases also referred to as “services” or “auxiliaries”. It should not be confused with the term “Utility” as is commonly used to describe the role of Eskom in the South African economy. Typically utilities may include the following systems: 

Potable water system



Sewage treatment system



Fire water system



Electricity supply system



Demineralised water system



Centralised gas system



Instrument air system



Compressed air system

1.5.23 Utility Flow Diagram (UFD) Utility flow diagrams (UFDs) are similar to P&IDs. It is a schematic representation of the utility systems within a process plant, showing all lines and other means required for the transport, distribution and collection of utilities. The process equipment in the UFD can be represented as a box with inscriptions (identification number) and with utility connections.

The representation and designation of all the equipment, instrumentation and piping should comply with the requirements of this Standard. Auxiliary systems may be represented by rectangular boxes with reference to the separate diagrams. Dimensions of the graphical symbols for equipment and machinery (except pumps, drivers, valves and fittings) should reflect the actual dimensions relative to one another as to scale and elevation. The graphical symbols for process measurement and control functions for equipment, machinery and piping, as well as piping and valves themselves, shall be shown in the logical position with respect to their functions. All equipment shall be represented such that the consistency in their dimensions is considered if not in contrast to the good representation of the equipment. 2.1.2

Drawing application

The Bentley and SmartPlant P&ID packages are the preferred drawing software applications to be used for developing Group Technology P&IDs. The software versions of these applications are to be specified prior to commencement of any P&ID work. 2.1.3

Line thickness should be adjusted when P&IDs are plotted in smaller size. In addition to the standard layers, the following conventions are recommended: 

Existing equipment (i.e. Items already installed/existing from previous projects that are indicated for clarity on the new P&IDs) and instrumentation need to be indicated in dotted line as opposed to solid line.



Items shown on more than one P&ID should show the item in solid lines in the main P&ID where the item is coded, and in dashed lines in any other views.



Instead of just changing the line type of the existing items, a second set of custom layers should be for each of the above layers as required. After inserting the symbol on the standard layer, the item can be moved to the required existing layer.

The symbols have been scaled to confirm the above scaling settings. Scalable symbols need to be scaled when inserted into the drawing and should be in proportion to the fixed symbols. It may be required to scale fixed size equipment symbols under certain circumstances due to P&ID density or other factors. This can be done using the Bentley procedures for scaling symbols. There are certain special cases where symbols need to be stretched (as opposed to scale). These are discussed in Clause 3.4. All P&ID’s should be developed on the A0 original size. Smaller plots may be made for convenience, but plots from different P&ID’s on the same size paper always yield the same relative scaling and sizing. 2.1.7

Symbology / symbol standards

Symbol standards are provided in the appendices. Since these may not be exhaustive, any omissions need to be brought to the attention of the author for clarification and inclusion in the standard. 2.1.8 2.1.8.1

Identification numbers for equipment should be located close to the relevant graphical symbol, and should not be written into it. Further details (e.g. designation, design capacity, design pressure, etc.) may also be placed under the identification numbers. 2.1.8.2

Flow lines or piping

Designation of flow lines or piping shall be written parallel to and above horizontal lines and at the left of and parallel to vertical lines. If the beginning and end of flow lines or piping are not immediately recognisable, identical ones should be indicated by corresponding letters. 2.1.8.3

Valves and fittings

Designation of valves and fittings shall be written next to the graphical symbol and parallel to the direction of flow. 2.1.8.4

Process measurement and control functions

The representation should be in accordance with the requirements stipulated in ISA-S5.1 and ISO 3511, Parts 1 and 4, latest revisions unless otherwise specified in this Standard. 2.1.9

Direction of flow

In general, the main direction of flow proceeds from left to right and from top to bottom. Inlet and outlet arrows are used for indicating the inlet and outlet of flows into or out of the diagram. Arrows are incorporated in the line for indicating the direction of the flows within the flow diagram. If necessary for proper understanding, arrows may be used at the inlets to equipment and machinery (except for pumps) and upstream of pipe branches. If a diagram consists of several sheets, the incoming and outgoing flow lines or piping on a sheet may be drawn in such a manner that the lines continue at the same level when the individual sheets are horizontally aligned. 2.1.10 Equipment lists While a separate equipment list is preferred, a tabular list may be included in the right top corner if required. 2.1.11 Equipment numbering All information required for numbering equipment on a P&ID is found in the KKS N.PSZ 45-45 numbering system. 2.1.12 Implementation standards Instrumentation tagging convention will be according to the relevant KKS / AKZ standards to ensure correct database generation and data interpretation. 2.1.13 Vendor supplied documents Any equipment or instrumentation supplied by a 3rd party vendor needs to be indicated as such on the P&ID. The convention is to enclose the equipment, instrument or group of equipment and instruments with a dash-dot line and write the text “Vendor” inside the box. In addition to this,

each piece of this equipment or instrument needs to have the vendor data indicated in the associated database.

2.2

Implementation options

Since this standard may not cover every possible situation, some flexibility is allowed for such eventualities. This section attempts to describe areas where such flexibility may be required. 2.2.1

Motors

Each piece of driven equipment should have a motor symbol attached, which is assigned a motor number. The motor symbol is in turn attached to the main equipment. The instrument bubble (MC) is then attached to the motor symbol. The motor tag name may be deleted from the P&ID (by selecting and deleting the text component) so as not to clutter the P&ID. Although it is not imperative to have a motor symbol for each piece of equipment it is highly recommended, since the motor symbol acts as a visual aid and generates a motor list, which may be used for procurement purposes. Consistency in this application is required to not create a meaningless motor list. 2.2.2

Conveyors

Conveyors are designed in a variety of shapes and sizes it is not practical to include all possible variations in length, inclination or other graphical permutations in the symbol library. Two belt conveyor symbols are included in the symbol library. One conveyor is a horizontal belt conveyor, and the other is an inclined conveyor. Both the symbols are for “short” conveyors. When the symbol is inserted, the symbol should be stretched (without distorting the proportions) to the correct length and shape. It may even be modified, rotated etc. if required (within the framework of consistency).Once the symbol is in the desired shape, then the symbol components need to be re-assembled and data attached to the symbol. The correct functional materials handling symbols should be used rather than just functional depictions. 2.2.3

Screens and underpans

The current version of the symbol library has the screen and its associated under-pan as a single symbol, hence creating a single equipment entry in the database. Should it be required to have the screen and the under-pan components as separate database entities with a different equipment tag number, the following procedure is recommended: 

Explode the screen symbol which includes the under-pan graphics.



Re-assemble the screen components using the P&ID tools and assign an equipment number.



Re-assemble the under-pan components using the P&ID tools and assign an equipment number.

Chutes

It is recommended that if a suitable chute is not in the library, that the specific chute is drawn manually and assembled in to a symbol for the P&ID. If the chute is more than a once-off requirement, then the chute drawing shall be sent to the responsible parties for inclusion in the library. 2.2.5

Agitators

The term agitator applies to mechanical mixers and aerators. 2.2.6
