RE: Re: Valve identification on P&IDs

Richard,

Identical numbers? You just did a lot of work for nothing.

In my experience, equipment, valves, etc. are assigned unique numbers. The reason for this is
that given a valve number for example, one would know exactly where this valve is located. This
method of identification would help you tremendously during installation and trouble shooting.

Sure it takes time to tag your P&IDs. It also takes time to physically tag the valves. But if you
have the resources (especially if you are a Design & Build Contractor), the return would
greatly offset the cost.

The spec call-out.

No sequential numbering. They will have the identical numbers underneath them.

Thanks. I'm getting really good feed-back here. Lots of food-for- thought.
