FARO Polypipe for gas

I have started taking the bits out the MH before she goes and have been checking the state of the LPG fill hoses. They need replacing so thinking of FARO Polypipe and fittings. The inlet hose from the fill point to the bottle and a join pipe to the next bottle. Using these fittings is not much more expensive than the heavy duty rubber stuff. The saving comes next time round when / if you have to change the piping. You can just use new olives and change the pipe at a fraction of the cost of new high pressure pipes. Also means that you can get the exact length you need rather than having them specially made or just looping them round the locker. Cannot find any information about FARO piping but if its similar to the yellow gas pipes it is going to last years. Far better than rubber. Bought new lightweight fixed cylinders from these LPG Shop guys.

depending on bore size might it restrict filling ?

It will not matter if it takes a bit longer. I may cut an old pipe up and have a look. Most of the high pressure hoses seem to have very thick walls but a small internal bore. I think the 8mm refers to the internal diameter. We shall see.
 
Years ago I bought a large reel of nylon tube from a boot sale for next to nothing.
Over the years I’ve been cutting it up for various uses including hoses for running LPG.
The pressure is 10 Bar & it doesn’t degrade over time even with liquid gas.

Just curious. Where on that pipeline does it say you can use for gas?
 
It doesn’t! But I’ve been using for years & it does not degrade, I’ve been keeping a close eye on the condition.
It’s very handy for filling with liquid gas as I can see when the gas is running through the tube & when it has stopped.
I can’t see why liquid gas should have an adverse effect on nylon.

Lpg is extremely corrosive which is why pipes are different testing on manometers and pigtails have a british standard and replacement cycle ....the link earlier shows a standard...for the use you are putting pipe too

To be honest. I think you would struggle in a court of law to convince them by saying"I kept a close eye on it"

BS3212 states what is required for gas pipework. Manufacturers name, identification, month and year of production bore size low or high pressure etc
 
I don’t think 10 bar is sufficient. Propane at 32C exerts a pressure of 10.3 bar and by 38C, which can happen in S Europe, it is up to 11.9 bar. It is even worse if you are using it on a refillable bottle because the differential pumping pressures can be significantly higher. I seem to recall reading somewhere that the pressure relief valves on propane tanks are set to 25 bar.
