Laying buried ducting under cobble for future natual gas pipe/connection

mullingar

This summer I plan to lay 180m2 of cobble in front of my house and the estate that I live in is hoping to connect to natural gas later in the year/next year (all depending on Bord Gais)

PDF Bord Gais - gas pipework installations for residential properties (pg12) states that a "protective sleeve" must be installed in there is vehicular traffic over it.

I would like to use very strong 3" plastic piping/ducting with 2 x 45 degree bends where it comes out at the side of the house, shaped like this:

_________Ground level
! !

\ \
..\ \
....\ \_________________________
......\___________________________ >>>> to boundry


This piping/ducting will do 2 jobs, to protect the pipe and to be a duct to pull the gas pipe through.

For any RGI's out there, would this be acceptable for an new connection? (Also is 3" ok?)

Hi how are things,

There is this type of pipework called TracPipe (http://www.omegaflex.com/trac/home/) whick is basically a stainless steel flexable pipe covered in a plastic flexable pipe. I have used this a number of times through & it complies with all gas regulations. I know you can get it fron BSS in Dublin & I presume it can be got easily enough else where.

Regards,

Thanks for that link, great product.

However, I'm leaning towards running a ducting system as I don't know what length/fittings/pipe-size the installer would need/use on it.

It does look perfect for use in a ducting system as it seems nice and flexible.

Do you know how flexible the standard PE pipe is?

The thing is you dont need a ducting system with this product. Its a pipe within a pipe, so if you lay it down before you lay the cobble, that will be your job done & save on the cost of the plumber installing it later on. For a domestic house, 3/4 is more than enough & later on the installer will look after the connections

MMmm, As this pipe will be on the Bord Gais side of the meter, I assume its Bord Gais staff that will connect the meter up.

Would Bord Gais be happy with that model hose installed (non-terminated) ? - Naturally to their required depth etc...

Also, Are Bord Gais fitters allowed to make a mechanical joint deep under soil? - I would need to cut the pipe short of the boundary wall because I simply dont know how much length they will need where they will "T" off the gas-mains to connect it.

Bord Gais should be more than happy with this. I have done this on a number of commercial projects & never had any issues after laising with them. But before you do anything, check with bord gais. Its been a few years since I worked on a project with gas.

You would be better off cutting the pipe overlength & leaving it over length for the installer to connect to. Better safe than sorry

tracpipe is not a pipe within a pipe it is a seamless stainless steel pipe in a plastic yellow sleeve.

bord gais will bring their own PE pipe from the road main up to your meter, your intended duct may be ok best to contact them and get the spec off them directly

i don't think it's acceptable to bury trac unprotected but am open to correction.

i buy it from hevac where it is sold in coils only dunno about bss, hate shopping there

If you use tracpipe don't get any water in it, it can become a nightmare to clear it.
