Request the block representation in the PID diagram for the blind flange
Thread Content
In the process flow diagram, how should the 8-character blind flange be represented as a block in CAD? (This is for future use when new pipes are added to expand production capacity.) This post was last edited by fredom on 2007-12-10 15:32]
It’s very simple – it’s just an 8. If you’re not being careless, the previous circle is usually filled in with color; it’s a circular disc.
Well, thank you. But I think there should be certain drawing standards for PID diagrams; it can’t just be drawn arbitrarily, right?
