Free AutoCAD P&ID equipment and piping symbols (DWG), ISO 10628-2 style

P&ID equipment and piping (ISO 10628-2 style): 149 ready-made AutoCAD blocks (DWG), free to download and use in your own projects, as a ZIP or one symbol at a time.

149 symbols for process flow diagrams and P&IDs as ready-to-use AutoCAD blocks, drawn after the symbol groups of ISO 10628-2: vessels and tanks, columns and their internals, heat exchangers, boilers and cooling towers, pumps, compressors and fans, valves, fittings and piping symbols. The equipment tag and the design data sit in attributes, so an equipment list can be read straight from the drawings.

Free library: version 1.2, updated November 9, 2026 · Pro library: version 1.0, updated November 9, 2026 · Check out what's changed

ISO 10628 Pro: 162 more symbols

Beyond the 149 free symbols above, Pro adds five more sections of the standard as AutoCAD blocks: qualifying symbols, fundamental items, transmission path, terminals and connectors, and semiconductor devices. One licence covers every section, and the free library stays free.

  • Every symbol is an AutoCAD block, drawn in millimetres at 1:1 and named IEEE_GROUP_NAME; insert it at scale 1.
  • Each block has two invisible attributes, DESC (the symbol name) and REMARKS (free text). All geometry is on layer SYMBOL.
  • Each DWG has a CATALOG layout with all its symbols on one sheet, ready to plot to PDF, and a README.txt lists every block.
  • Plain DWG files in AutoCAD 2018 format, plus a second ZIP per section in AutoCAD 2010 format. No add-in is needed.
  • The 149 symbols of the free library come in the same download as their own DWG, so you have the whole set in one place.

Attributes for parts lists

Every equipment block has a visible TAG attribute (for example P-101). The data you normally put on an equipment list are invisible attributes: SERVICE, CONTENT, VOLUME_M3, DESIGN_PRESSURE and DESIGN_TEMP for vessels; DUTY_KW and AREA_M2 for heat exchangers; FLOW_M3H, DIFF_HEAD_M and POWER_KW for pumps; and MATERIAL, MANUFACTURER, MODEL and PID_NO for all of them.

Valves show VALVE_TAG and SIZE, and pipelines show LINE_NO.

How to use the library

  1. Unzip the file and open the DWG. Copy the symbols you need into your P&ID, or drag the blocks in from DesignCenter (ADCENTER).
  2. Equipment is inserted by its centre; the short stubs mark the preferred connection points and can be deleted. Valves are inserted at the left pipe connection, with both connections on a 5 mm grid.
  3. Scale the symbol to the size of your sheet with the INSERT scale (for example 1.5 for an A1 drawing); the attribute text scales with it.
  4. Double-click the block (or run EATTEDIT) to enter the tag and the design data.

About ISO 10628-2

ISO 10628-2 specifies the graphical symbols for chemical and petrochemical process flow diagrams and P&IDs, such as vessels, columns, heat exchangers, machines and fittings. Instrument symbols are not part of it; they follow ISA 5.1 (see the instrumentation library).

These symbols are our own drawings after the symbol groups of the standard. They are not copied from it, and the library is not certified against it. Company and project standards often draw some symbols differently; change the blocks if yours do.

What changed in each version

Version 1.2 · November 9, 2026

Frequently asked questions

Are these symbols ISO 10628-2 compliant?
They are drawn after the common forms of the ISO 10628-2 symbol groups, but were not checked clause by clause and are not certified. If a client requires strict conformance, compare the shapes with your copy of the standard.
Does the library include instrument and control symbols?
No. Instrument bubbles, control valves with actuators and signal lines are in the separate ISA 5.1 library. The valve bodies in this library are the process valve symbols of ISO 10628-2.
Can I use the symbols in commercial projects?
Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty. Please do not redistribute or resell the library; see the library terms.
Can I change a symbol or add attributes?
Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.
Where do I find a ready-made set of these symbols for AutoCAD?
AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
