    At my old company the installers could put in a Boiler and leave no marks on the Round Black Iron. I asked how they did it and they just said very carefully. Some guys would paint the pipe after a Steam Install,but it would smell on the first few start ups. But it looked good.

    Don't have to be as careful with these.

    Black pipe is higher tinsel than galvanized pipe. Am I correct? Less carbons in the metal?

    Well, why black pipe in the first place? I see the gas company use black pipe and then paint it.

    Cheaper. Cost money to galvanize it.

    I always thought it was Code to protect all gas piping exposed to the elements. At the Gas Utility we had to prime and paint. And different Regs had different colors: Gray for 30#s and under. I think it was Red for 60#s and Green for 90#s of Pressure. But nobody seems to paint Rooftop piping. :dunno:

    Actually it is a very heavy coating they put on the pipe so they can run a millivolt charge down the pipe to stop corrosion

    We have a 10 and 16 inch pipeline that runs north and south through the middle of our place and last summer then had to dig it up because a "pig"the little thing they install between different products to clean all the old out before the new goes in. Any way the pig has electronics aboard that can tell a bunch of into about the pipeline, they thought there was a problem right between our place and the neighbor to the south so they dug it up

    It was a false alarm, but I was surprised at how good the pipe looked like after they peeled the coating back, looked like the day it was laid, and that was about 60 years ago

    What I have seen is that the pipe from the gas company does have cathodic protection and all is well. However, after the meter is fair game with no protection. The paint after the meter is only for aesthetics. The customers side corrosion happens at ground level.

    I recently replaced the steel LPG lines feeding my house. Some of it was on top of the ground and some was buried maybe 2 inches in the ground at the most. None of it had any protective coating on it just bare black pipe. It was all in surprisingly good shape. I was talking to my lp supplier and they had replaced some new steel pipe that was only in the ground 6 months. It was full of pin holes. Come to find out they had built the house on an old feed lot. Apparently cow s*** and steel don't mix.

    After it gets out of the ground the corrosion is much less of a threat, the air doesn't stay wet for months at a time, the ground can

    Live near a Power Plant,the Gas Pressures are 600 psi! When a Relief Valve Blows,usually at 2:00am,it sounds like a Train is running through the House. I Hope their Piping is well Protected!

    Now you see the Gas Utes replacing the supply's around the City where all the old bare steel is deteriorating with Plastic. Supposed to last a lifetime. We'll see.

    I suppose if you think about it the steel has lasted a "lifetime".
