What do the main P&ID symbols mean?

P&ID symbols are standardized graphical notations used to represent equipment, piping, valves, instruments, and control functions in a process system. A readable P&ID combines these symbols with line types, tags, and labels so engineers can understand how the process is connected and controlled.

Equipment

Symbols represent items such as pumps, tanks, vessels, compressors, heat exchangers, and other process equipment.

Piping and valves

Different line and valve symbols show process connections, flow paths, isolation points, and valve types.

Instrumentation

Instrument bubbles, tags, and signal lines identify measured variables and control functions such as flow, pressure, temperature, and level.

Is EdrawMax a good P&ID tool?

EdrawMax is useful for creating and documenting P&IDs with editable symbols, templates, connectors, and export options, especially when ease of use and visual communication matter. For projects that require engineering databases, automated tag validation, plant-model integration, or formal compliance workflows, specialized plant-design software may also be required.

What our users say

Ethan Carter, Senior Process Engineer

I’ve been in the game for thirty years and I’ve used every clunky CAD tool under the sun. Usually, making a simple P&ID is a total headache—you're fighting the software more than designing the flow. Wondershare actually gets it. The drag-and-drop symbols aren't just "close enough," they actually meet the standards. It’s a breath of fresh air not having to build every valve from scratch. It’s snappy, doesn't crash every five minutes, and frankly, it saved my bacon on a tight deadline last week.

Ryan Mitchell, junior Design Associate

Real talk, as a new hire, I thought I was gonna be stuck doing the grunt work in some ancient, overpriced software. My lead told me to try out Wondershare for our new P&ID layouts and it’s honestly a vibe. The UI is super clean—not that cluttered 90s look most engineering tools have. It’s basically plug-and-play. Plus, the price point doesn't break the bank, which was a huge selling point for our small firm. It’s legit.

Jason Brooks, Technical Consultant

I’m constantly hopping between my Mac at the home office and the PC in the field, so I need something that doesn’t throw a fit when I switch platforms. This tool is spot on. The sheer variety of ISO and ISA symbols is impressive—it covers all the bases for my hydrogen plant layouts. No more "mucking about" trying to find the right pump icon. It’s streamlined my workflow massively. If you’re tired of the "industry standard" bloatware, give this a go. It’s a game changer.
