Answer 1

There are several types of materials approved for gas work. The codes for the local jurisdiction should always be checked but in general

steel pipes
copper pipes
yellow brass pipe
ductile iron
aluminum pipe
PVC pipes
PE pipes may be used.

Steel Pipes
Steel pipes can be used above ground as long as corrosion due to the environment and the conveying gas is of no problem. Steel pipes together with copper pipes are the most common materials used inside buildings.

Copper Pipes
Copper pipes used in gas systems should be of type L or K and approved for gas.

Yellow Brass Pipes
Yellow brass pipes may be approved for inside installations.

Aluminum Pipes
Aluminum pipes should not be used in the ground. Aluminum is not approved in all jurisdictions.

Ductile Iron
Ductile iron pipes may be approved in some jurisdiction for underground work.

PVC Pipes
PVC - Polyvinyl Chloride - pipes may be used in pipelines buried outside a building.

PE Pipes
PE - Polyethylene - pipes may be used in pipelines buried outside a building.

Flexible Connectors
Flexible connectors are used to connect appliances to gas sources. Flexible connectors must be approved.

There should be a 'building code' for you area. (city, county, or state) Start with the 'Building Inspector' or the nice people at code enforcement, they can answer your question. To my knowledge, black iron is acceptable for natural gas. Copper is only acceptable for liquid petroleum, and lead needs to be removed.
Hope this helps.
Oh, for the water side of LOW pressure water heaters, copper or lead is okay, but you will find the lead a continual nuisance. Lead is not approved for any new or repair work in residential housing, just about anywhere in the US.
