gas pipe

[sijaysee]

anyone know if there are regs as to how close
a gas pipe can be an electric cable?

Yes, BS6891:2005 8.16.2

Separation of installation pipework from other services
Where installation pipes are not separated by electrical insulating material, they shall be spaced as follows:
a) at least 150 mm away from electricity meters and associated excess current controls, electrical switches or sockets, distribution boards or consumer units;
b) at least 25 mm away from electricity supply and distribution cables.

interesting!
job im on now has a gas pipe that runs from the boiler
and then horizontal (ish) for about 24" and then heads south
and eventually into the floor.

unfortunately the cables from a socket run underneath
the pipe as it goes along the wall

 

[sijaysee]

what would be considered as "electrical insulating material"?

 

[Pensdown]

Are you sure the cable is closer than 25mm to the gas pipe? And if it is, can't you move it a few mm?

 

[sijaysee]

well in all reality , the pipe is quite close to the surface
and so i could probably chase a bit more to achieve
the 25mm.

i was just wondering about the implications of anyone
drilling through both the pipe and the cable, or is
that not the issue as long as they are in the correct
zone where they cross?

am i right in thinking that i just have to wrap the
pipe in electrical insulating tape?

As far as I understand it, gas pipes shouldn't be chased in, but its out of scope for this forum... ask in the plumbing forum... my knowledge of the gas regs only extends to a quick soundbite about how close electrical stuff can be to them

internal copper gas pipes should not be enclosed unless within a purpose made conduit, ventilated at each end .

 

[sijaysee]

well these particular pipes are buried in the wall.
not much i can do about that!!

anyway i've made sure that theres 25mm between
the cables and the pipe

and i've wrapped the pipe in insulting tape

 

[ColJack]

oh heck...

i've just studded out the walls in my kitchen to hide the pipes for the rads and the gas..

will it conform if i drill some 20mm holes into the loft ( 1st floor flat.. ) and some at skirting level under the units?

AFAIK, this only applies to new builds. Correct me if I'm wrong.

 

[bengasman]

No. Any alteration made to a building needs to comply with building regs.
Just because it is an exising dwelling does not mean it is ok to construct an enclosure that is liable to gas accumulation.

gas pipes can be chased into walls as long as they are covered first with suitable protection from concrete/plaster (use duct tape) and then the chase must be filled in with either cement or plaster to ensure there are no air gaps. ( i am corgi reg)

Did it call you a f*cking b*stard?

Perhaps you could post your kennel club number and I'll pass this on to them ... You may not be registered for much longer

craigs4040 posted the correct way to do this earlier ...

This is also the safe way to do it.
