بوست ف اللذيذة وأنت نشيط الصپح
فيه ٣ حاجات هتسمع عنهم كتير لو انت involved ف مجالنا أي كان تخصصك ، أو تخصص شركتك سواء engineering أو production
BFD - PFD - P&ID
وانا النهاردة جايلك بشرح مبسط جدا لكل واحد فيهم
تعريفه ، الغرض منه وهكذا علشان نقرأ مع بعض ، و ٣ صور للتعبير عن كل واحد فيهم وتعرفة physically شكله أيه
let's begin ⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️
=====================================
1️⃣-BFD (Block Flow Diagram)
↪️process drawing used tosimplify the basic structure of a system.
↪️the simplestform of the flow diagrams used in the industry.
↪️Blocks represent anything from a single pieceof equipment to an entire plant.
=====================================
2️⃣-PFD(Process Flow Diagram)
↪️diagram commonlyused in engineering to indicate the general flow of theplant process.
↪️displays the relationship betweenmajor equipment of a plant facility and does not showminor details such as piping details and designations.
↪️Process flow diagrams of a single unit process will include⤵️⤵️⤵️
☑️Major process piping
☑️Major bypass & recirculation lines
☑️Major equipment symbols, names, and
☑️identification numbers
☑️Process flow directions
☑️Major control loops
☑️Interconnections with other systems
☑️Stream Identification
☑️Heat & Mass Balance
↪️PFDs generally do not include⤵️⤵️⤵️
☑️Piping class or piping line numbers
☑️Pipe size
☑️Instrumentation
☑️Minor bypass lines
☑️Isolation and shut-off valves
☑️Maintenance vents and drains
☑️Relief and Safety Devices
☑️Pipe fittings and flanges
=====================================
3️⃣-P&ID(piping & instrumentation diagram)
↪️It is a pictorialrepresentation of the piping, equipment, instrumentation,and control devices.
↪️P&ID preparation is initiated during
FEED and is further updated during detail engineering.
↪️P&IDs are updated according to vendor data, design reviewcomments, HAZOP recommendations, and as-builtchanges.
↪️P&ID shows the interconnection of process equipment andthe instrumentation used to control the process.
↪️In theprocess industry, a standard set of symbols is used toprepare drawings of processes.
↪️The instrument symbolsused in these drawings are generally based on the
International Society of Automation (ISA) Standard S5.1
↪️CAD system is used to develop the P&IDs.
↪️Most details that are available from other types ofdocumentation (e.g., instrument loop diagrams,vessel data sheets) are not recommended forinclusion on P&IDs.
↪️P&ID shows equipment with simple outline
representation.
↪️Equipment is not drawn to scale, howeverequipment relative to one another both in size andgeneral orientation must be maintained.
↪️P&ID shows nozzles on equipment, including
spares, as single lines.
↪️P&ID indicates nozzle sizes unless the size is
implied by piping connections.
↪️P&ID shows equipment item number and
title/service as a minimum.
↪️P&ID indicates internals for equipment as dashedlines. Details of internals that have no significantbearing on the piping design and layout orequipment operation are omitted.
↪️P&ID indicates auxiliary system requirements forindividual pieces of equipment (e.g. lube oil systems, seal flush systems, turbine gland leak-offpiping, sample systems) on auxiliary P&IDs.
↪️P&ID indicates jacketing requirements for
equipment and jacketing/tracing requirements forpiping.
↪️P&ID indicates the type of insulation (e.g.,
personnel protection, heat conservation) for
equipment as part of the equipment data.
↪️P&ID indicates insulation thickness where
applicable.
↪️P&ID indicates a piping serial number and piping class.
