I guess "gas" pipe may be too generic. What they use for gas pipe around here is steel pipe that has a black coating (which can be sanded off). The galvanized version of the same basic pipe is used for water service. (Galvanized is not used for gas, since it has a tendency to flake off & clog up gas pilots)
In any case, what you get could (and probably will be) different from location to location. |
