Not in most places I've been. Once the gas line exits the meter and the relief, they really are not involved.
Federal law requires galvanic protection or Stainless piping in high pressure gas lines.
As fas as low pressure gas piping, we are talking what, 30" of water column? You have to do an awfully lousy job to not be able to hold 30" of water. Snoop's main advantage is the UV pigment. The best cheap stuff is to buy kids bubble blowing mixture. Next best cheap is dish soap mixed with water.
