Can someone tell me what this signifies on a P&ID?
Thanks

My guess is pipe lagging. Is there a note H on the drawing legend?

Thanks for the reply. No, there is no Note H. It makes sense although there is no insulation at this time on it. Except where it is in reach of people.

My colleague thinks insulation or a wall penetration

Another possibility is heat tape.

I would second Tom's answer. Looks like heat trace and insulation.

George,

From P&ID's I've seen before, it looks most like the common lagged pipe symbol.
It can vary from software to software somewhat. The H should represent either the medium flowing through the pipe, such as a chemical, or else it might represent the service, such as Heating. The 1" should denote the pipe diameter.

Attatched are a couple of examples of symbols that are similar.
