The gas company might take a dim view of you screwing or soldering onto the
gas line.
Gas distribution (and all other underground pipeline companies) companies
spend considerable time/money on cathodic protection. Small amounts of
electricity is run through pipelines, whenever a new service, or main
extension, or any other significant addition or subtraction is made to the
piping system they will take readings between the pipe and adjacent damp
soil, and add large cathodic blocks as needed to bring the readings into
their allowable range.

You are right: When writing I was focusing more upon fastening a block to
the web of a WF beam than to the gas pipe. Clamping the block to the pipe
would be appropriate. The same technique would work for steel or iron pipes.
