Underground lpg gas pipe

[Thoggy]

Hi
Got to put some lpg gas pipe underground and just weighing up mdpe gas pipe versus Tracpipe, just seen the cost of Tracpipe wow!!!
Only thing is it seems that the Tracpipe is going to be better to bend for when I connect abouts ground, I see the mdpe has electrofused joints which I wouldn't have a clue how to do so will leave that, has anyone used mdpe before for gas and how did you go on?
At the minute the safest bet looks to use the Tracpipe but it's extremely expensive.
Thanks for any advice

Have a look at gastite and if your doing elec fusion joints there's a separate qualification 😉

Use mdpe then when you come above ground put it through a hockey stick

to protect against uv and then use these

Any reason why you cant use coated copper ! if price of TracPipe is to expensive !

How bendy is the mdpe?

It's slightly stiffer than speedfit

Bring it up in a hockey stick and then use a transition coupling.
Why are you needing to bend it tight?

How much are you going underground you can buy tracpipe in 5m or 10m kits, i had to run a LPG pipe underground through 4 inch ducting and i used tracpipe 5m installation kit came with fittings for both ends cost me £80 and done within 15 mintues

It's about 20meters and need 28mm

Copper potentially get crushed underground even if coated. Make sure to lay at correct depth for foot or road traffic as required.
