How bad are galvanized pipes for natural gas?

Well.......I, for one, don't agree. Here in Canada, we adhere to the CSA Standard B149.1-05, which indicates that steel gas piping needs to conform to ASTM A53, which is a standard for seamless and welded, black AND hot dipped galvanized pipe.

C'mon, if you're putting in your dirt pockets at the appliance, the internal issue is moot. If the piping is exposed to the elements and the ambient environment is harsh, (salt spray, etc.), then the benefit of galvanized outweighs any remote possibility of 'clogged orifices'. Honestly, I've been a pipefitter for 30 years myself - how many of you out there have even seen a clogged orifice? - Never, I'd bet

How bad are galvanized pipes for natural gas?

I'm buying a condo in Providence, RI. The place has old galvanized natural gas pipes. It seems like most houses in this area have the same type of pipes, and the real state agents / sellers say that it's fine to have them. However, the inspector say that it's really bad since the pipes...

There was a time when some jurisdictions did not allow galvanized because of the possibility of the zinc coating flaking off inside the pipe, and clogging orifices and valves. Most places do allow it now. Figure the drip legs take care of problems. Some areas still allow black outside but require it to be painted. The advantage of Black is that it is a little cheaper.

AT ONE TIME IN MINNESOTA GALVANIZED GAS PIPING WAS AGAINST CODE REQUIREMENTS BUT THAT WAS OVER 30 YRS.AGAO

IT'S A FAR BETTER MATERIAL THAN BLACK PIPE IF YOU'R NOT WELDING IT...I'M A 40 YEAR MASTER PLUMBER

Ask the local building code agency for the current requirement for new construction. Black iron pipe is almost universal however plastic pipe is allowed in some areas. It is legal to keep what you have if it met the then local building code at the time of installation.

the 2 previous are correct however if it is a high salt area ie coastline then galvinived pipe may be used as to help prevent corrosion.

It is alowed here in Oregon on the coast

first, i believe galvanized pipe is no longer acceptable for natural gas......natural gas has a high sulfur content along with methane - back in the days , this was ok - i believe your condo has this to avoid exterior corrosion.....at least in texas, it is not ok as a form of material -

i would look into change the gas lines from galvanized to black pipe. if you are worried about them rusting you can paint the black pipe with a good quality oil based paint.
