P&ID Blocks and Layering Conventions

[jbratcli]

Hi All,

Well firstly Im an old timer acad user, started back in 1987 and since I have mostly been working on Civils/ Architectural projects.

Because of the downturn I find myself working from home and being asked to set up symbols and layering conventions for P&ID drgs, the most urgent being steam, compressed air, HV and water.

Ive spend a day surfing thru Google and although I have found a few things there was nothing definitive.

Just wondered if someone can point me in the right direction, If I recall there is info but only if I pay a £600-£700 subscription fee which being the way things are I cant afford.

Many thanks in Advance

John

Look over at caddepot.com, search on PID, I found 9 different ones, I can't tell if they are all for money or not but worth a look.

Can be a funny topic.

There does not seem to be any national or international standards set down yet; probably because it is such a huge subject.

We have discussed this before and shared some info here-

But it seems to be down to your industry sector and company as to what you use.

In the US we have the ISA and many companies belong to and follow their standards for symbols, method, etc.

I agree, unless you want a bunch of phone calls from an engineer or site. I would get yourself some proper ISA guidelines for blocks, line types etc.. Save you a bunch of headaches
