What should be included in a P&ID?

What should a P&ID include?

  1. Mechanical equipment with names and numbers.
  2. All valves and their identifications.
  3. Process piping, sizes and identification.
  4. Miscellaneous – vents, drains, special fittings, sampling lines, reducers, increasers and swagers.
  5. Permanent start-up and flush lines.
  6. Flow directions.

Who is responsible for P&ID?

P&ID is a detailed form of PFD. Process engineers, in coordination with piping, instrumentation, electrical, and safety engineers are responsible for preparing the P&IDs. P&ID drawing has more importance as the basic document for piping engineers for the purpose of material procurement and deciding of pipe routing.

What is PFD drawing?

A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

What is the difference between PFD and P and ID?

A Piping and Instrument Drawing (P&ID) includes more details than a PFD. It includes both major and minor details of the chemical process. P&ID is a detail form of PFD. Process engineers, with coordination of piping, instrumentation, electrical and safety engineers, are responsible for designing P&ID’s.

How do you mark up engineering drawings?

When marking up drawings or documents, use this standard multi-color pen system:

  1. red – incorporate items (add)
  2. green – delete items.
  3. blue – comments for information only, not to be added to drawing.
  4. yellow – items marked as “correct”
  5. orange – items addressed by drafting (pickups) – to check your own work.

How do you make a P&ID in Excel?

How to Create P&ID

  1. On the File menu, point to New, point to Engineering or Industrial Automation, and then choose a diagram type.
  2. From symbol libraries, drag and drop instrument shapes to the canvas.
  3. Use pipeline shapes to connect major equipment.
  4. Add other kinds of shapes such as valves.

How do I create a PFD?

How to create PDF files:

  1. Open Acrobat and choose “Tools” > “Create PDF”.
  2. Select the file type you want to create a PDF from: single file, multiple files, scan, or other option.
  3. Click “Create” or “Next” depending on the file type.
  4. Follow the prompts to convert to PDF and save to your desired location.
