As you may or may not know, the installation of plumbing pipes and fixtures is governed by a set of rules, known as the Universal Plumbing Code (or “UPC”).  The UPC rules are rarely more important than when dealing with gas lines.  This is especially true for black iron gas lines.

What is a black iron pipe?

You may be familiar with “galvanized pipe for gas”.  Black iron pipe is, simply put, the same thing, but without the zinc coating.  The zinc coating on galvanized pipe for gas is meant to keep the pipe from corroding from contact with moisture.  While it does its job pretty well, over time, it still does corrode.

Since black iron pipe does not have the zinc coating, it will corrode very quickly if exposed to water.  For this reason, it cannot be used for water or waste piping.  It is, however, very popular for gas piping.  One reason is because it is less expensive than galvanized pipe for gas.  Another is that it is easier to differentiate it from water piping when crawling around under a home.
