bonding LARGE gas pipes

[brs73]

hello there
a quick question.
what methods would you use to bond a large (possibly 4inch?) gas pipe???
thanks

 

[NoSparks]

Same as a small gas pipe except I would use a couple of clips joined togther and both screwed up tight.
(Don't forget to burnish the pipe before connection)

Is there a pipe hanger near to where you are you could crimp and bolt in to that. Failling that you could use bandit tape.

 

[NoSparks]

I don't think I have yet seen a pipe hanger that I would guarentee to give a 0.01 ohm connection over a period of even say 3 years.

Pipe hangers arent generaly tightened round the pipe 2 Clamps round it or check wholesalers you may be able to get one big enough

Knock an earth spike through it.

Knock an earth spike through it.

just get your apprentice to do it job is that

Indeed, my local Newey's have a special on gas main earth spikes at the moment too. If they've sold out now there's always the drill and self tap option, you can stick a bolt in it as long as it's painted yellow.

If it's plastic I wouldn't bother, if it's in a commercial/industrial premises and the gas isn't connected yet why not get a stud welded to the gas pipe then fit a lug to cable.

exactly what i was about to say, if it's bigger than 3" it'll be welded rather than screwed so if the welder fella is still on site ask him nicely to put a stud on it for you.

As said get an inch of 8mm threaded bar welded onto the pipe, or use the longer size earth clamp.

As Lenny says.....
Re- Nosparks post... I'm certain I read somewhere that joining 2 standard earth clamps to go round a large diameter pipe is not considered a satisfactory means of termination,cant remember where,may have been in an NIC publication.

Why not use a furse BN175 pipe bond for pipes 50mm to 200mm

Or something from here perhaps?

Could the straight setscrew on Steves page be used instead on a ring crimp when bonding earth cables?
