--->With oil steam boiler what pipes are being used? galvanized steel? OR galvanized iron pipes?<--

LS123

hello all,

I was wondering what type of pipes are used with steam oil boiler.

(Q-1) Is it galvanized steel OR galvanized iron pipes?

Just wanted to know what type of pipes I may have in my basement. I am guessing these pipes been at my house since 1950 connected to the 70 year old steam boiler.

All the pipes seem to be in good shape (no leaks or noticeable rusting. I will get them inspected when I have a experienced, licensed professional specialized in Steam oil heating systems.

After the inspection,I would like to spray paint them (spray paint graded for heat) They are not insulated. I plan to insulate them with Fiberglass Pipe Insulation.

(Q-2) is it ok to paint them after the inspection?
(Q-3) I would painting the pipes and insulating them, it would extend the life span of the pipes. This seems logical question when apply to other things like wood etc, but I just wanted to be sure.

Thanks,
\-LS

The pipes are black steel, not galvanized. The fittings are either cast or malleable iron. Your new MegaSteam should be piped in with the same thing.

Most of the piping use is black steel. Galvanized would be a shiny aluminum color. I would not waste any time painting the pipes unless your basement is very damp. Insulation is a good idea. 1" fiberglass is what I would use.

@EBEBRATT-Ed , except winter, I run a de-humidifier 24x7 and keep the humidity level about 55. accumulated water from the
de-humidifier get pumped to out side. Thank you!

Look on the pipe for the name BYERS. If you see that name the piping is wrought iron and if that name is not there then it is as the other guys have said, "black iron". Wrought iron piping was used by some contractors in the 1950's and earlier. The contractors would sometimes use the wrought iron pipe for the steam supply lines but it was usually left for the return lines that were below the water line due to it's resistance to corrosion. Byers, went out of business sometime around 1955 so your piping could be either or a combination of both. Steam lines usually last a life time and the return lines last until they plug up or corrode/rust through.

Good morning @retiredguy ,

I looked at all the supply pipes from boiler to radiators, and the return lines. They do not have "Byers"
Most likely the all the pipes are black iron. Yes all the pipes are in good shape.

Thank you!
