The tubing shall undergo a seamless or welding process. Tension, bend, and flattening tests shall be performed to make sure that it must adhere to the mechanical properties of the standard. The hydrostatic test shall be applied, without leakage through the weld seam or the pipe body. Nondestructive electric test shall be made to make sure that the full volume of the pipe must be in accordance with the standard. The purchaser shall have the right to perform any of the inspections and tests set forth in this specification where deemed necessary to ensure that the pipe conforms to the specified requirements.

Does galvanized pipe comply with ASME B36.10-10M, 53/A53M, or A106? If so, approvable perI do not have a copy, but the title ofis "".Sounds like galvanized pipe to me.
The issue with gavanized pipe is the possibility of the coating flaking and then plugging valves and orifices.
If drip/dirt legs are present the risk is low but I would note the non standard use of the galvanized fitting in the gas piping system.
