P&ID Symbol - Indentification help
P&ID Symbol - Indentification help
(OP)
Hi all,
I was going through a P&ID today and I saw an unfamiliar symbol, I think it might be an hydraulic actuator, but I'm not to sure. It's a circle with a curly tail. I had a look through the ISO standards but nothing came up. Can someone please provide an answer. I've attached a picture.
Thank you.

RE: P&ID Symbol - Indentification help
You have some opinions:
A- All projects are supposed to have a P&ID Legend Sheet showing all symbols and their description. Have you looked for the Legend Sheet for your Project?
-
B- Have you met the Lead Process Engineer for your Project yet? Go find him or her and ask them what that symbol means. If they don't know you are in real trouble.
-
C- Use the Internet to find what you need by doing simple searches. Such as:
https://www.lucidchart.com/pages/p-id-symbols-lege...
or
https://www.google.com/search?q=p%26id+symbols&...
Sometimes its possible to do all the right things and still get bad results

I did a web search and nothing came up. I also checked the legend but it wasn't on there either. I haven't spoken to the Lead Process Engineer, I'll do that first thing when I get into the office.
Thanks again.

In all seriousness though, adammal44's suggestion seems very plausible. And as pennpiper said, ask the process engineer. I've also had luck once in a while asking the CAD guys who actually modify the PIDs all day long, they usually have a decent handle on what everything represents.
RE: P&ID Symbol - Indentification help
I admit to never seeing that convention having viewed thousands of P&ID markups from dozens of companies.
