I believe that the plumbers can go further than 10' between supports.
For that matter we can too.
That looks to be about a 2" gas line, the NEC support requirements for 2" RMC are 16', 3" RMC and above the requirement is 20'.
Looks like we could run 2" RMC beside the gas line and make the chin-up bar into parallel bars for Olympic training.
I sure would not want to see this in my backyard.
