Hey Anton,
No… I guess that it really doesn’t make a difference in terms of actual piping… it’s more of a “tomato” vs. “tuhmahto” thing… but I’d really like to find out what other piping designers’ conceptions are.

When there is an actual lateral branch from a header (and the original header continues down the pipe rack, for example) the line number changes, as you say, and is this branch still considered a “header” or is it now a sub-header”?

I know that it may not matter… which is probably why I’m so OBSESSED with it (smiling)…
