Gas piping should not be bonded to the electrical grounding system. It should have a separate bonding connection that complies with local building codes. Bonding gas piping to the electrical grounding system can create safety hazards and is not recommended.
Piping material used for forming gas would be 316L stainless steel.
To get the electricity from where it came from to where it is going, Just like water piping, gas piping, sewer piping, etc.
No. Meters are set for different outgoing pressures. Higher pressure coming out meter allows for smaller piping to be used. A gas pressure regulator will be needed at each appliance to reduce gas pressure to required gas pressure for appliance. Gas company should be able to take care of meter. Gas company or plumber should know how to size piping.
Gas piping must be bond to the appliance it serves.
The purpose of a drip leg in the gas piping is used as a device to capture dirt and debris from entering the furnace.
Most codes do not allow Galvanized piping/fittings on gas piping. I have used galvanized pipe/fittings on exterior gas piping before in the state of Michigan but other states do not allows this. Check with your local code authorities.
Natural gas can leave a residue in piping due to impurities in the gas such as sulfur compounds or moisture that can react with the metal of the piping or form deposits over time. These residues can accumulate and clog the piping, leading to reduced flow efficiency and potentially causing operational issues. Regular maintenance and cleaning of the piping can help prevent the buildup of residues.
i dunna??
No it will not poison you. Copper piping is used extensively in Medical Gas applications. "TYPE L" signifies the wall thickness of the piping.
As far as I know, for underground piping use plastic, for above ground steel or copper. That is the practice in the UK, but I don't know about the US. I would be surprised if it is different. We did have underground steel pipes but these are now being replaced with plastic and all new is plastic (underground)
Yes, you can. You could also use pipe dope, according to my dad. He works for infra source installing natural gas piping.
