I protect things that stick out, like water pipe connections from the tank, tank drain valves etc. I protect these because I did have one busted off on a stoney track many years back. I have never tried to protect water pipes etc. and never had any issues with them being damaged on stoney roads.

You could use some of that convoluted split automotive tubing to cover sensitive lines, it is pretty damage (and heat) resistant, easy to fit and you can buy it in different sizes from the likes of Repco, et al.

we have covered the vulnerable bits under our van with pool noodles - just slit then secure with cable ties. Actually made a metal guard for the tap

Would be a lot easier for ADR to allow steel gas pipelines like the rest of the world accepts as safe.

My gas lines are all sheathed in garden hose. It is a legal requirement to protect them from possible damage.
I would see fatigue as a potential issue with steel (as it is with copper). Plastic would be much more durable.

John Guest water pipe seems to be bullet proof.

Cheers,

Use garden hose, class B irrigation poly pipe, things that have some resistance to them from abrasion and doesn't cause other friction/rubbing issues.
Either fit it to the pipes/hoses with them disconnected, or split them length ways and attach/retain with things like zip ties.

Electrical cable plastic tubing and foams will get eaten rather quickly if your really going out into the boonies.

I have seen a caravan that had the gas line running inside garden hose from the bottle all the way to the fridge. Worked fantastic as far as protection goes. The owner was worried about the drain holes in the floor in the boot allowing bugs into the boot so placed a mat over the holes. The 2 X 9 KG bottles were also fitted inside the boot.
The problem was that he had a leak where the gas hose fitted to the gas cylinder ( due to poor machining at manufacture ).
Anyway the leaking gas filled the boot, travelled along between the pipe and garden hose to the 3 way fridge, where the pilot light provided the ignition source. The flame then flashed back inside the garden hose to the boot which promptly exploded.
New boot lid and chairs and one shaken owner.
Investigation by the gas authorities found the poor machining and the fact that the garden hose was one piece from inside the boot all the way to the fridge inside the van.
Solution was to replace bottle, cut garden hose and remove an inch of hose where the gas line exited the boot, and the mat that was blocking the drain holes disappeared.

First and single most important consideration here is.

Gass bottles should NEVER be installed in enclosed spaces without adequate ventilation.....there should always be adequate ventilation.

Adequate ventilatioon is not a couple of little holes or a pissy little vent.

Use the fart test.....if you farted where your gas bottles are housed......how long with the smell hang around.

Explosive gasses will hang around, just the same as the smell.

I have seen a number of campers and caravans where I have no idea how they comply with either gas or transport regulation due to the way the gass bottles are housed.

The garden hose was not the problem.....gass bottles in an enclosed space was the problem.

ALL gass systems are prone to leakage where the bottle meets the pipes....it must be assumed that any gass bottle will at some time leak.

cheers

I have also fitted mud flaps underneath the van for protection with a flap of rubber screwed next to to the tap like a mud flap except I call it a tap flap.

Cheers
