Can you use black gas pipe for above ground?
Black iron/steel pipe can be used, in most areas, for above ground piping. You cannot have threaded joints underground, they must be welded. Most areas do not allow copper inside the home for gas. Click to see full answer. Also asked, can I bury black gas pipe?
What type of pipe is required for underground gas lines?
Old thread, but for FWIW, check with the local AHJ; metallic underground gas pipe is usually required to be buried 12", factory coated, and the joints need to be coated with approved gas pipe paint primer and hand wrapped spirally with approved plastic tape.
Can black pipe be buried?
Black or galvanized pipe cannot be direct buried, unless they have a protective wrap, (I would not use black pipe even then). The epoxy coated black pipe is not much better than having paint on it, because the epoxy coating can be damaged during assembly or installation, and if the spot is not protected it can rust out in a couple of years.

What type of pipe is used for underground natural gas?
Polyethylene gas piping systems are specifically engineered and certified for the underground environment.
Can black steel pipe be used for natural gas?
To put it simply, black iron pipes can be used for gas under your home, in the crawl space or basement, inside the walls, or in the attic – basically where it is not exposed to earth or the elements (moisture). This is because of the lack of anti-corrosive coating.
What is the best gas line to run underground?
Polyethylene (PE) gas piping is the most widely used plastic piping material for the distribution of natural gas. PE has a well-documented inertness to both the external soil environment and to natural gas.
Can I run black gas pipe outside?
It is very common to see black pipe used for your natural gas line and sprinkler system lines. Since black pipe has no protective coating, it may rust easily in wet or humid environments. To stop the pipe from rusting or corroding on the outside, you should provide a layer of protection on the outside of the pipe.
Can galvanized pipe be used for natural gas line?
Unlike old galvanized pipes which were poorly coated with zinc, modern galvanized pipes are of a better quality. You can therefore use them for natural gas transportation without the zinc flaking off and clogging gas regulators and burner units.
Why is black pipe used for gas lines?
Black iron pipe is used to transport natural and propane gas in residential applications. Black steel pipe is manufactured as seamless which makes it a better type for gas transportation and fire sprinkler systems since it can prevent fire better than galvanized pipe.Mar 19, 2022
How long will black gas pipe last underground?
Answer: Black iron pipes coated with a protective layer, can last more than 10 years. If it doesn't have any protection it would last less than 10 years.Sep 11, 2021
How deep should a gas pipe be buried?
A gas service pipe should normally be laid with a minimum depth of cover of 375 mm in private ground and 450 mm in footpaths and highways.Oct 4, 2021
Will Natural Gas Corrode Galvanized pipes?
Would you rather have a leaking water pipe or a leaking gas pipe? I am sure you would be happy if you could avoid both altogether.
Black Pipe vs. Galvanized Pipe for Natural Gas
Black iron pipes and galvanized pipes are basically the same thing only that galvanized pipes have a zinc coating to protect them from corrosion. Black iron pipes are named as such due to the black iron oxide coating which forms when the pipes react with oxygen.
Why Black Pipes are Preferred for Natural Gas than Galvanized Pipes
If you check in many homes, you will notice that most natural gas pipes are black pipes and hardly galvanized pipes. Why is this the case though?
Can You Mix Galvanized and Black Pipe for Natural Gas?
Another question that troubles homeowners when installing natural gas pipes is whether it is a good idea to mix black and galvanized pipes or fittings in the connections.
What is black iron pipe?
What is commonly called black iron pipe is steel, NOT cast iron. They used to use galvanized here, but that also rusts out after several years. Today, around here, they use a lot of epoxy coated steel pipe, Click to expand...
How many pages are there in the fuel gas code?
There are over a hundred pages in the National Fuel Gas code that cover piping and fittings that can and can not be used for gas piping. I suggest you get a copy.
Does black iron last a year?
San Diego, CA. Black iron would not last a year underground , in wet soil. Cast iron soil pipes are deep, and are in fact CAST IRON, not steel. What is commonly called black iron pipe is steel, NOT cast iron. They used to use galvanized here, but that also rusts out after several years.
Can galvanized pipe be buried?
Black or galvanized pipe cannot be direct buried, unless they have a protective wrap, (I would not use black pipe even then). The epoxy coated black pipe is not much better than having paint on it, because the epoxy coating can be damaged during assembly or installation, and if the spot is not protected it can rust out in a couple of years. I once saw a section that was so bad it looked like a piece of Swiss cheese. Unless it is a very short run, I use polyethylene plastic. CSST has to be "sleeved" for underground installation.
How long have black iron pipes been in service?
There have been "black iron" pipes (actually steel pipes with the black oxide from the mill) in service underground for close to 100 years with little or no failure. Certainly there have been steel pipes with no protective coatings that have failed in one way or another with less than ten years in the ground.
What is gas piping made of?
Most distribution and service gas piping installed today is with special plastic piping but the main transmission piping is still made of steel pipe, albeit with a plastic coating and the welded joints are specially wrapped and sealed against corrosion.
Can galvanized pipe be used for natural gas?
Galvanized pipe is never used on natural gas, as the pipe contains galvanization on the inside as well, and can flek off and clog up orifices. Visit chandler's homepage! I "used" to believe galvanized could not be used for gas lines until I moved to Florida. It was code where I lived (Ocala).
Can copper be used on natural gas?
Any area which has high sulfur content in their gas, the local codes will prohibit the use of any copper on natural gas. Banned. Rule And/Or Policy Violation. Galvanized pipe is never used on natural gas, as the pipe contains galvanization on the inside as well, and can flek off and clog up orifices.
Can magnent stick to trac pipe?
Its a flex gas line with a plastic yellow coating on it specifically designed for gas, so yes, a magnent would stick to it.
Is trac pipe magnetic?
Tracpipe is not magnetic. The flexible pipe that you see in these kinds of installations (TracPipe, Gastite, Gasflex, etc.) is a type of CSST (Currogated Stainless Steel Tubing). It is not magnetic since it is stainless steel. Just because you aren't getting a magnet to stick to it does not mean it is non-metallic.
