Piping Spacing

RE: Piping Spacing

Looks like it's based on flange diameter and bolting up wrench clearance.

I hate Windowz 8!!!!

RE: Piping Spacing

Corgas,
That is a copy of a typical"Company Standard". The company I was with for most of my 45 years as a Piper had the same chart. I have seen the same basic chart with other company names in the title block and some with 2" or 3" between pipes where this one has 1". It is not a Copyrighted document.

I have never seen anything in any of the Piping Codes or Industry National Standards.

prognosis: Lead or Lag

RE: Piping Spacing

concur -- nothing in the Code Books.

RE: Piping Spacing

Pipeline codes require a minimum of 12" clear of foreign objects.

Which code will that be?

I checked ASME B31.3 and there was nothing in there.
